What’s new in Compressor?
What’s new in Compressor 4.1?
Compressor 4.1 introduces a new design and various new features, detailed below.
New interface
The interface in Compressor 4.1 has been updated with the following new features:
•
A dark, neutral background—identical to the backgrounds in Final Cut Pro X and Motion 5—to
enhance color perception and put the focus on your media
•
Three dierent interface views:
•
Current view—the default view—where you prepare transcoding jobs and submit
batches. In Current view, you can access the Settings and Locations pane, which contains
precongured transcoding settings, destinations, and save locations that you can assign
to your media les. In Current view, you can also access the inspector pane, which displays
information about your transcoding settings and jobs.
•
Active view, which shows information about jobs currently being transcoded.
•
Completed view, which shows information about jobs that have been
successfully transcoded.
For more information, see Interface overview on page 8.
1
Basic transcoding workow
Compressor 4.1 oers a simplied transcoding workow that speeds up common tasks. For more
information, see Transcode les on page 12.
Destinations
Destinations are transcoding instructions combined with a scripted job action, such as burning
a DVD disc or uploading to a video-sharing website. You can choose from a number of built-in
destinations, or create your own destinations for custom transcoding tasks. In Compressor
4.1, destinations replicate much of the functionality previously available in batch templates
in Compressor 4.0. For more information, see View and modify a destination’s properties on
page 50.
Distributed transcoding
Compressor 4.1 simplies distributed processing—the act of sharing transcoding work among
multiple computers or computer processors.
•
What was previously referred to as a “cluster” in Compressor 4.0 is now called a “group” of
computers. To congure a group of computers and set up distributed processing, you turn
on access to your computer and then create a set of shared computers. If you can’t nd a
computer on your network, you can manually add it to the computer list.
•
Options for turning on access to your computer, as well as setting up a group of shared
computers, are located in Compressor preferences. For more information, see Transcode
batches using other computers on page 101.
For more help and information about new features in Compressor 4.1, see the white paper,
Transition to Compressor 4.1.

What is Compressor?
Compressor is an application that transcodes media les into a variety of formats. You can use
Compressor to create les for many uses, including:
•
Viewing on Apple devices such as Apple TV, iPad, iPhone, iPod, or iTunes using high-denition
(HD) or standard-denition (SD) formats (including H.264)
•
Publishing to video-sharing websites including Facebook, Vimeo, and YouTube using
QuickTime
•
Burning to DVD or Blu-ray disc using H.264, MPEG-2 for DVD, and Dolby Digital formats
•
Podcasting using H.264, AAC, and MP3 formats
Compressor comes with built-in settings that you can use to transcode les into the most
common media formats. Compressor also provides precongured destinations that transcode
les and then perform actions on the transcoded les. For example, if you transcode a source
le using the built-in “Publish to Vimeo” destination, the destination outputs a high-quality
QuickTime movie le, and then automatically publishes the movie le to your Vimeo account.
In addition to transcoding source les, you can use Compressor to:
•
Create custom settings and destinations: You can use a variety of formats to build custom
settings and destinations tailored to your unique transcoding workows. For example, you can
create a custom setting with specic frame dimensions or with video and audio lters applied.
And when you create a destination, you can apply a job action that is performed after the le
is transcoded—such as sending an email message or running an Automator workow.
•
Create settings to transcode Final Cut Pro X and Motion projects: You can create a custom setting
in Compressor and then use it to transcode Final Cut Pro or Motion projects. For example, you
can create a setting that outputs a le with the bit rate of your choice.
•
Transcode les using a network of shared computers: If you need more processing power and
shorter transcoding times, you can create a group of shared computers to distribute and
speed the transcoding process.
•
Create Compressor droplets: If you need to provide a very simple workow for yourself or other
users, you can create a Compressor droplet, a standalone application that lets you transcode
media les in the Finder, by dragging and dropping.
6
Compressor workow
The basic process of transcoding les in Compressor is described below.
Import your media into Compressor
The rst step in the transcoding process is to add one or more media source les to Compressor.
You can add media les from your computer or a connected hard disk. Each media source le
in Compressor is called a job. Each transcoding session, containing one or more jobs, is called
a batch.
Apply transcoding instructions
After you add a source le, apply one or more transcoding instructions to it. Compressor provides
a variety of precongured transcoding instructions called settings, which you can use to convert
les to the most common media formats. If you want, you can modify the setting’s properties to
meet your requirements.
Compressor also provides a number of precongured destinations, which combine settings and a
post-transcoding action, such as uploading your le to YouTube or burning a Blu-ray disc.
Choose an output location
Designate a location on your computer or on a connected hard disk where you want to save the
transcoded media le. You can choose any of several precongured locations, including your
computer desktop, your Movies folder, or the source folder of the original media. You can also
choose a custom location.
Submit your media for transcoding
After you assign settings or a destination and specify an output location, click the Start Batch
button to begin the transcoding process. You can monitor the progress of the transcoding in
the Active view. After transcoding is complete, you can see information about the settings or
destinations you used in the Completed view.
Chapter 2 Compressor basics 7
Interface overview
Preview area
The Compressor window has three views: Current, Active, and Completed. You can switch
between these views by clicking a view button at the top of the window.
Current view
Current view is the default view in Compressor. Current view is where you prepare transcoding
jobs and then submit your batch. When you open Compressor for the rst time, Current view
displays two basic areas:
Batch area
•
Batch area: When you add source les to Compressor, they are displayed in jobs in the lower
half of the main window. Each job in the batch area displays information about the source
le, the job’s transcoding instructions (setting, output location, and output lename), and any
post-transcoding actions that have been added (or that are part of the destination assigned to
the job).
•
Preview area: Above the batch area, the preview area shows how your media le will look and
sound after transcoding. Here you can also add metadata and markers to be included in the
transcoded le.
Chapter 2 Compressor basics 8
You can expand the Current view to display additional areas:
Settings/Locations pane
Inspector pane
•
Settings and Locations pane: Click the Settings & Locations button at the top-left corner of
the Compressor window to expand this area, and then click Settings or Locations to display
the individual panes. The Settings pane provides quick access to all the built-in destinations
and settings, as well as to any custom destinations or settings that you created. Likewise, the
Locations pane provides quick access to all the built-in save locations, and to any custom
save locations that you created. You can add settings, destinations, and locations to a job by
dragging an item from these panes to the job in the batch area.
•
Inspector pane: Click the Inspector button in the upper-right corner of the Compressor
window to expand this area. The inspector pane has several views that change, depending on
the item that is selected. When you select a batch (by clicking the background of the batch
area), the Batch inspector appears, displaying basic information about the current batch.
When you select a job in the batch area, the Job inspector appears, displaying a summary of
the job’s transcoding instructions as well as controls for adding metadata and modifying job
actions. When you select a specic transcoding instruction in the batch area (one of the rows
under the job), the General, Video, and Audio inspectors appear. These three panes contain
adjustable properties that you can use to customize the setting or destination.
Chapter 2 Compressor basics 9
Active view
In Active view, the Compressor window displays status information about batches (and their
constituent jobs) currently being transcoded. In this view, you can monitor progress bars as well
as pause or cancel the transcoding process.
Completed view
In Completed view, you can view information about batches and jobs that have been
successfully transcoded, as well as information about items that failed to transcode.
A list of batches is shown on the left side of the window. Click a disclosure triangle beside a
batch to see its constituent jobs and output les. Select a batch, job, or output le in the list to
see additional information in the inspector pane (on the right).

Simple transcoding overview
When you add a source le to Compressor and apply output instructions (all done in Current
view), you create a transcoding job. You can add more jobs to the batch, and then submit the
batch for transcoding.
Each job in a batch has has several parts:
•
Source le: The media le that you want to transcode.
•
Setting: The transcoding instructions that specify how the le will be processed. Compressor
provides a variety of built-in settings that you can use to output les in common media
formats. Additionally, Compressor provides a number of precongured destinations—one or
more settings combined with an automated action that is performed after transcoding. For
example, if you use the Publish to Facebook destination to transcode a source le, Compressor
outputs a high-quality QuickTime movie le. Then the destination’s job action publishes the
transcoded le to your Facebook account.
•
Location: The place where the transcoded le will be saved. You can use one of the built-in
locations, or specify a new location.
•
Filename: The title of the transcoded le. You can use the default lename (the name of the
source le) or type a custom lename.
•
Job action: Optionally, you can add a post-transcoding action to a job, such as burning a DVD,
uploading to Vimeo or YouTube, and so on. Each of the built-in destinations already contains a
job action.
In the example below, two jobs make up the batch:
The rst job uses the built-in Create DVD destination to output a Dolby Digital audio le and an
MPEG-2 video le. The transcoded les will be saved to the source folder (the folder where the
source media is stored), and after the les are transcoded, they’ll be burned to a DVD (using the
Create DVD job action).
11
The second job uses two built-in settings (Small and HD 720p) to create a small QuickTime le and
a high-denition (HD) QuickTime le. The transcoded les will be saved to the desktop. Because
there’s no job action, the user will have to manually move or otherwise distribute each le.
Transcode les
This job will transcode the source
The easiest way to transcode media les in Compressor is to use or one or more built-in settings
or to use a built-in destination (settings that are combined with a post-transcoding job action,
such as uploading to Facebook or burning a Blu-ray disc).
Set up the rst transcoding job in a batch
1 Click the Add File button in the batch area.
Batch area
Add File button
2 In the le window that appears, select a media le and then click Add.
3 In the Settings window that appears, do the following:
a Select one or more transcode settings or a destination from the list.
The settings list contains basic settings, as well as destinations, grouped by category. To
choose a specic setting, click the disclosure triangle beside a destination or a setting group
(Podcasting, for example), and then select one or more settings.
Important: For destinations, always select the destination name. If you select a setting that’s in
the destination, the destination’s job action will not be used when processing the job.
b Choose a save location from the pop-up menu.
4 When you’re satised with your setting and location choices, click OK.
The new job is displayed in the batch area. The job includes a thumbnail of the source le and
the transcoding output instructions (setting, location, and lename). If you chose multiple
settings, or a destination with multiple outputs, each output appears in a separate row. If you
chose a destination, its job action appears in the upper-right corner of the job area.
To learn more about the built-in destinations and settings, see Built-in settings on page 16 and
Built-in destinations on page 17.

of the source le.
3 Click the Add Outputs button inside the job in the batch area.
4 In the Settings window that appears, select one or more settings or destinations, choose a save
location, and then click OK.
Tip: Shift-click to select consecutive settings; Command-click to select nonconsecutive settings.
The output instructions that you specied appear in the job. If you chose multiple settings
or a destination with multiple outputs, each output appears in a separate row. If you chose a
destination, its job action appears in the upper-right corner of the job area.
Chapter 3 Simple transcoding 13
5 To change the name of a le to be output, double-click its name in the Filename column, and
then enter a new name.
The default name assigned to each transcoded le is the source lename appended with the
extension of the format used during transcoding (.mov or .mp4, for example).
Note: If you see an alert icon to the left of the lename, the lename assigned to that output
row has already been used.
6 To view the properties of a setting, select an output row, and then open the inspector by clicking
the Inspector button in the upper-right corner of the Compressor window.
Depending on the setting you're viewing, general, video, and audio properties are displayed in
the inspector. For information about modifying these properties, see View and modify a setting’s
properties on page 20.
Add and remove job outputs
You can add additional transcoding instructions to a job by adding one or more output rows.
You can also remove output rows.
Do one of the following:
m To add an output row: Position your cursor over an output row in the job, and then click the Add
button that appears at the end of the row. Then, in the window that appears, select one or
more settings, choose a location, and click OK.
m To remove an output row: Position your cursor over the output row that you want to remove, and
then click the Remove button that appears at the end of the row.
Chapter 3 Simple transcoding 14
Preview how a transcoded le will look and sound
After you’ve set up a job, you can preview how your source le will look and sound after it has
been transcoded.
Note: Retiming and interlacing property adjustments (that you make in the Video tab of the
inspector) are not displayed in the transcoding preview.
1 In a job, select the output row that includes the setting you want to preview.
2 If the Comparison button in the preview area isn’t already selected (highlighted blue), click it
to turn on comparison previewing.

You can also customize a built-in setting or create your own custom setting from scratch. For
example, you can create a custom setting to convert progressive video to interlaced video,
or to convert 29.97-fps video to 23.98 fps video. Before you create a custom setting, view the
related built-in settings to see if any of those meet your needs. If one does, or if it comes close,
duplicate that setting, and then modify any properties that you need to change. The advantage
of duplicating a setting, rather than creating a new setting from scratch, is that many of the
properties are already congured, and thus, you’ll need to make fewer adjustments to the
setting. For more information, see Create custom settings on page 21.
Built-in destinations
Destinations, available in the Settings pane, combine one or more settings and a post-encode
job action, which automates tasks such as emailing, copying, and moving transcoded les.

Advanced adjustments overview
For basic transcoding jobs, you can use the built-in settings and destinations that come with
Compressor. However, if you have complex or custom transcoding specications, you can make
adjustments to the built-in settings and destinations in a number of ways:
•
For a custom transcoding job that you will use only once, apply a built-in setting or
destination and then modify its properties in the inspector. See View and modify a setting’s
properties on page 20 and View and modify a destination’s properties on page 50.
•
For a custom transcoding job that you will use more than once, create a custom setting or
destination (by duplicating and modifying a built-in setting or destination). See Create custom
settings on page 21 and Create custom destinations on page 51.
You can also customize the various other components of a Compressor batch, including save
locations, job properties, job actions, and batch properties. See Work with locations on page 52,
View and modify job properties on page 54, and Work with batches on page 61.

To learn more about a setting’s properties, see About formats and settings on page 23.
The type of setting you modify determines whether or not the setting will be saved.
•
If you modify the properties of a custom setting, the changes are saved automatically.
•
If you modify the properties of a built-in setting, the changes are not saved.
In this case, if you want to save your changes, you can create a custom setting. For more
information, see Create custom settings on page 21.
Create custom settings
You can create your own custom settings, either based on an existing built-in or custom setting,
or from scratch. You can also create groups of settings.
Create a custom setting by duplicating an existing setting
To save a modied setting for future use, you must create a custom setting. The easiest way to do
this is to duplicate a built-in setting and then modify its properties in the inspector.
1 In the Settings pane (press Shift-Command-1 if it’s hidden), select the setting that you want to
duplicate.
To reveal individual settings in a setting category, click the disclosure triangle next to the
category name.
2 Choose Duplicate from the Action pop-up menu at the bottom of the pane.
A copy of the setting (appended with the word, “copy”) appears in the Custom area of the
Settings pane.
3 To modify the properties of your new custom setting, adjust the controls in the General, Video,
and Audio inspectors.
If the inspector is hidden, click the Inspector button in the upper-right corner of the
Compressor window.
For example, you can change a setting’s frame controls or add a video or audio eect to the
output le.
To learn more a setting’s properties, see About formats and settings on page 23.
Chapter 4 Advanced adjustments 21
Create a custom setting from scratch
You can also create a custom setting without duplicating a built-in setting. Because it’s easy to
accidentally introduce transcoding errors, this method is recommended for advanced users only.
1 In the Settings pane (press Shift-Command-1 if it’s hidden), choose New Setting from the Add
pop-up menu .
2 In the dialog that appears, choose a transcoding format from the pop-up menu, enter a name
and description for the setting, and then click OK.
The new setting appears in the Custom area of the Settings pane.
3 To modify the properties of your new custom setting, adjust the controls in the General, Video,
and Audio inspectors.
If the inspector is hidden, click the Inspector button in the upper-right corner of the
Compressor window. For example, you can change a setting’s frame controls or add a video or
audio eect to the output le.
To learn more a setting’s properties, see About formats and settings on page 23.
Create a group of custom settings
If you want to organize your custom settings, you can create a setting group. For example, if you
want to quickly add several settings at the same time, you can apply a setting group to a job.
1 In the Settings pane (press Shift-Command-1 if it’s hidden), choose New Group from the Add
pop-up menu .
The group appears in the Custom area of the settings pane and is selected by default.
2 In the dialog that appears, type a name for the group and click OK.
3 Drag custom settings into your new group in the Custom area of the Settings pane.
Tip: If you want to add a built-in setting to the group, you must duplicate the setting (as
described in “Create a custom setting by duplicating an existing setting” above) and then add the
duplicated setting to your group.
Rename a custom setting
You cannot rename a built-in setting; however, you can duplicate a built-in setting and name
your new custom setting as you choose.
Do one of the following:
m In the Settings pane, double-click a custom setting and type a new name.
m Select a custom setting in the Settings pane. Then, in the General inspector, type a new name in
the Name eld. (If the inspector is hidden, press Command-4.)

About formats and settings
Compressor provides a variety of transcoding formats to create les playable on a variety of
media platforms—from Apple devices to Blu-ray discs to websites, and so on. Each of the built-in
settings in the Settings pane uses a specic transcoding format compatible with the following
industry-standard platforms.
You can see which format a setting is based on by looking at the summary information at the
top of the inspector.
The setting is based
on this format.
Platform and/or useUse video settings based on
these formats
Devices like Apple TV, iPad, iPhone,
and iPod touch; and iTunes
Web delivery, including YouTube,
Facebook, and Vimeo
The built-in AIFF File, CAF File, and WAVE File settings use the Common Audio Formats
transcoding format. This format encodes AIFF (Audio Interchange File Format), CAF (Apple Core
Audio Format), or WAVE (Waveform Audio File Format) les. You can also create custom settings
that use the Common Audio Formats transcoding format.
The properties of built-in and custom settings that use this transcoding format are located in the
General inspector and Audio inspector. These properties are described below.
Important: When you add a setting (or a destination that includes settings) to a job, Compressor
analyzes the source media and then automatically assigns the most appropriate setting
properties (based on the setting’s transcoding format and the characteristics of your source
media le). It’s recommended that you use the automatically assigned setting properties.

The built-in OpenEXR Image Sequence and TIFF Image Sequence settings use the Image
Sequence transcoding format. This format encodes a variety of image sequence le types used
in motion graphics, including TIFF, OpenEXR, JPEG, PNG, and more. You can also create custom
settings that use the Image Sequence transcoding format.
The properties of built-in and custom settings that use this transcoding format are located in the
General inspector and Video inspector. These properties are described below.
Important: When you add a setting (or a destination that includes settings) to a job, Compressor
analyzes the source media and then automatically assigns the most appropriate setting
properties (based on the setting’s transcoding format and the characteristics of your source
media le). It’s recommended that you use the automatically assigned setting properties.

dominance or a conversion to progressive scanning). There are four options:
•
Same as Source: Maintains the same scanning method used by the source media le.
•
Progressive: Scans complete frames (not frames divided into interlaced elds).
•
Top First: Scans interlaced elds, giving dominance (eld order) to the top eld, also known
as eld two, the upper eld, or the odd eld.
•
Bottom First: Scans interlaced elds, giving dominance (eld order) to the bottom eld, also
known as eld one, the lower eld, or the even eld.
•
Scale image to preserve aspect ratio: Select this checkbox to scale the output les to use square
pixels and maintain the original aspect ratio (which results in an increase or decrease in the
number of horizontal and vertical pixels).
Cropping and padding
Customize the nal cropping, sizing, and aspect ratio using the Cropping & Padding properties.
Cropping removes video content from an image. Padding scales the image to a smaller size while
retaining the output image’s frame size. For more information about these properties, see Modify
frame size overview on page 69.
•
Cropping: This pop-up menu sets the dimension of the output image. The custom option
allows you to enter your own image dimensions in the elds; other options use predetermined

•
Adaptive details: Select this checkbox to use advanced image analysis to distinguish between
noise and edge areas during output.
•
Anti-aliasing level: Sets the softness level in the output image. Double-click the value and
then manually enter a new value or drag the slider to the right to increase softness. This
property improves the quality of conversions when you’re scaling media up. For example,
when transcoding SD video to HD, anti-aliasing smooths jagged edges that might appear in
the image.
•
Details level: Sets the amount of detail in the output image. Double-click the value and then
manually enter a new value or drag the slider to set the value. This sharpening control lets you
add detail back to an image being enlarged. Unlike other sharpening operations, the “Details
level” property distinguishes between noise and feature details, and generally doesn’t increase
unwanted grain. Increasing this value may introduce jagged edges, however, which can be
eliminated by increasing the “Anti-aliasing level” slider.

output le: either faster and lower quality, or slower and better quality. Options include:
•
Single Pass CBR: This is the fastest MPEG-2 encoding mode. It provides good quality,
especially at bit rates between 5 and 9 Mbps.
•
Single Pass VBR: This mode aims to maintain constant quality (at the expense of constant bit
rate) for the transcoded video le. For most standard-denition (SD) media les at bit rates
of 3.5 Mbps and above, this mode provides good to excellent quality and transcodes quickly.
•
Single Pass VBR (Best): This mode provides the best possible quality output for SD video at bit
rates of 3 to 3.5 Mbps and above.
Chapter 4 Advanced adjustments 39
•
Two Pass VBR: This mode uses two passes—one pass to analyze the entire source video
stream, and a second pass to compress the le. This mode takes longer and provides a
better-quality le than the one-pass modes, and is recommended for source media les with
a substantial dierence between the most and the least complex scenes.
•
Two Pass VBR (Best): This mode provides the best possible quality output, and outstanding
quality at bit rates of 3 to 3.5 Mbps and above for HD and SD video.
•
Motion estimation: This pop-up menu sets the amount of motion processing that will be
performed on the le. There are three options:
•
Good: The fastest processing setting. Use this setting when there is relatively low motion
between frames. In general, use Good with the one-pass encoding modes.
•
Better: Provides very good results even in the presence of complex interlaced motion. In
general, use Better with Single Pass VBR (Best) and Two Pass VBR (Best).
•
Best: The slowest processing setting. Use for the most complex motion and for interlaced
source les. In general, use the Best mode to maximize quality when using Single Pass VBR
(Best) or Two Pass VBR (Best).
•
GOP structure: This property is available only when the “Frame rate” property is set manually
(does not use Automatic).
Note: Automatically determined properties, including the “Frame rate” property mentioned
above, are assigned by Compressor based on your source media le. Therefore, "Automatic”
properties are strongly recommended.
Compressor provides three methods of grouping frames, or “pictures,” in encoded video: as
I-frames (intra-frames), P-frames (predictive frames), and B-frames (bi-predictive frames). The
“GOP structure” pop-up menu includes several methods of combining frames:
•
IP: Use IP only if your media contains fast motion that isn’t encoded with sucient quality
using an IBBP or IBP structure.
•
IBP: Use IBP only if your media contains fast motion that isn’t encoded with sucient quality
using an IBBP structure.
•
IBBP: Recommended for majority of MPEG-2 encoding situations.
Note: For most MPEG-2 encoding situations intended for use on a DVD, choose IBBP as the
GOP structure setting, and a GOP size of 15 for NTSC, or 12 for PAL.
•
GOP size: This property is available when the “Frame rate” property is set manually (does not
use Automatic).
Note: Automatically determined properties, including the “Frame rate” property mentioned
above, are assigned by Compressor based on your source media le. Therefore, "Automatic”
properties are strongly recommended.
This slider species how many frames are contained within a GOP (group of pictures). The
values available in the slider are are determined by the GOP structure property (described
above). The maximum GOP size you can choose within Compressor is 15 frames (NTSC) or 12
frames (PAL and 720p). The minimum GOP size for all video formats is 6 frames (closed GOP) or
7 frames (open GOP).
•
Automatically select bit rate: Select this checkbox to have Compressor automatically compute
the best bit rate for the output le, based on the duration of the source le. To manually adjust
the bit rate, deselect the checkbox and drag the “Average bit rate” and “Maximum bit rate”
sliders (or enter values in the adjacent elds).
•
YUV 422 color encoding: This property appears in most built-in settings that output MPEG-2
les. Select this checkbox to use YUV 422 color encoding for superior chroma quality.

Automatic to have Compressor choose the key frame interval rate (the displayed value is 0
with Automatic on; the actual value is determined during the encoding process).
•
Data rate: Sets the number of kilobits per second (kbps) required to deliver your video le.
Drag the slider or enter a value in the eld. This setting is useful if you have a specic bit rate
(such as a DSL connection) or amount of space (on a DVD or CD- ROM).
Important: When you set a data rate, you override other codec quality properties because the
codec compresses the le as much as it needs to based on its data rate limit.
•
Multi-pass: Select this checkbox to turn on multi-pass encoding that uses additional analysis
of video frames to produce a high-quality output le. For faster (single-pass) transcoding, turn
this feature o by deselecting the checkbox.
•
Allow frame reordering: Select this checkbox to potentially provide a better-quality output le
by allowing Compressor to reorder video frames during transcoding.
Cropping and padding
Customize the nal cropping, sizing, and aspect ratio using the Cropping & Padding properties.
Cropping removes video content from an image. Padding scales the image to a smaller size while
retaining the output image’s frame size. For more information about these properties, see Modify
frame size overview on page 69.
•
Cropping: This pop-up menu sets the dimension of the output image. The custom option
allows you to enter your own image dimensions in the elds; other options use predetermined
sizes. The Letterbox Area of Source option detects image edges and automatically enters crop
values to match them. This is useful if you want to crop out the letterbox area (the black bars
above and below a widescreen image) of a source media le.
•
Padding: This pop-up menu sets the scaling of the output image while retaining the output
image’s frame size. The custom option allows you to enter your own scaling dimensions in the
elds; other options use predetermined dimensions.
Quality
The following properties determine how the video will be resized, retimed, and otherwise
adjusted when transcoded.
•
Resize lter: This pop-up menu sets the resizing method. There are three options:
•
Fast (Nearest Pixel): Provides the fastest processing time.
•
Better (Linear Filter): Provides a medium trade-o between processing time and
output quality.
•
Best (Statistical Prediction): Provides the highest output quality, but takes longer.
•
Retiming Quality: This pop-up menu sets the retiming method. There are four options:
•
Fast (Nearest Frame): Uses a copy of the nearest available frame to ll the new
in-between frames.
•
Better (Motion Adaptive): Uses deinterlacing on areas of the source le that contain
movement to produce good-quality output.
•
Best (Motion Compensated): Uses deinterlacing on areas of the source le that contain
movement to produce high-quality output.
•
Reverse Telecine: Removes the extra elds added during the telecine process to convert the
lm’s 24 fps to NTSC’s 29.97 fps. Choosing this item disables all the other Quality controls. For
more information, see About reverse telecine on page 74.

•
Adaptive details: Select this checkbox to use advanced image analysis to distinguish between
noise and edge areas during output.
•
Anti-aliasing level: Sets the softness level in the output image. Double-click the value and
then manually enter a new value or drag the slider to the right to increase softness. This
property improves the quality of conversions when you’re scaling media up. For example,
when transcoding SD video to HD, anti-aliasing smooths jagged edges that might appear in
the image.
•
Details level: Sets the amount of detail in the output image. Double-click the value and then
manually enter a new value or drag the slider to set the value. This sharpening control lets you
add detail back to an image being enlarged. Unlike other sharpening operations, the “Details
level” property distinguishes between noise and feature details, and generally doesn’t increase
unwanted grain. Increasing this value may introduce jagged edges, however, which can be
eliminated by increasing the “Anti-aliasing level” slider.

Add and modify job actions
A job action is an automated action performed on a media le after it's transcoded—such as
burning a DVD, uploading to Vimeo or YouTube, and so on. If a job contains a job action, a gear
icon is shown in the top-right corner of the job.
Create DVD job action.
You can add a job action to a job, as well as modify a job action’s properties, in the Job inspector.
Note: A job action is included in each of the built-in destinations provided with Compressor. For
more information, see View and modify a destination’s properties on page 50.

For information about the properties of each job action, see Job action properties on page 59.
Fix a job action that has an alert icon
If a job action displays an alert icon , there’s an issue with the source le or the action
properties. For example, you may need to provide your Vimeo account name and password in
the job action’s properties; without that information, Compressor cannot upload the transcoded
le to your Vimeo account.

Job action properties
Compressor comes with a set of job actions that are used in destinations as well as in jobs. The
job action assigned to a destination or job performs an automated action after transcoding—
usually copying the transcoded le to a new location.
For more information about adding or modifying a job action in a job, see View and modify job
properties on page 54. For information about choosing a job action that’s part of a destination,
see View and modify a destination’s properties on page 50.
The properties of job actions available in Compressor are described below.

for. You can choose Hard Drive to create a disk image (.img) le that you can burn to DVD
media at a later time using the Disk Utility application (available in the OS X Utilities folder).
Note: The items in this menu are determined by your system’s available options. For example,
when no Blu-ray or DVD drive is detected, only the Hard Drive option is available.
•
Layers: This pop-up menu sets the type of disc that will be created. There are three options:
•
Automatic: Detects the inserted disc’s type. For Automatic to work, you must insert the disc
before clicking Burn. Additionally, Automatic always creates a single-layer disk image when
Hard Drive is selected as the output device.
•
Single-layer: Creates output for a single-layer disc. You can use this option to treat a duallayer disc as a single-layer disc.
•
Dual-layer: Creates output for a dual-layer disc. When you choose Hard Drive as your output
device, the “Dual-layer” option creates a disk image in dual-layer disc format. Choosing
“Dual-layer” when using a single-layer disc may result in an error while burning the disc,
depending on the project’s length.

You can also use Compressor to output an image sequence. For more information, see Image
Sequence on page 33.
Chapter 5 Advanced tasks 63
Work with surround sound les
Import and modify surround sound les
There are two methods you can use to add audio les to a batch to create a surround sound job:
•
Manually assign audio les to surround sound channels.
•
Append audio lenames with channel identier codes and have Compressor automatically
map the lenames to the correct surround sound channels.
Each method creates a source le in a job to which you can add a setting that supports surround
sound audio outputs, such as a Dolby Digital setting or an AIFF setting.
After creating the surround sound source le, you assign output information to the job (one or
more settings or a destination and a location and name for the transcoded le) and transcode
the batch that contains the job.
Create a surround sound source le by manually assigning channels
1 Do one of the following:
•
At the bottom of the batch area, choose Add Surround Sound Group from the Add pop-up
menu .
•
Choose File > Add Surround Sound Group.
The channel assignment window opens.
2 To assign a source audio le to each channel, do one of the following:
•
Drag the source audio le from the Finder to the icon for a specic channel.
•
Click the icon for a specic channel, select a source audio le intended for that channel, and
then click Open.
3 To include a video le, click the Add Video button, select a video le, and then click Open.

Chapter 5 Advanced tasks 65
Create a surround sound source le using channel identier codes
You can add channel identier codes to the lenames of surround sound les in the Finder and
then add the les in Compressor.
1 In the Finder, append the lename of each audio le with the appropriate channel identier code:
For example, if the audio le for your left front channel is named “nal audio_left.ai,” you would
name the le “nal audio_left-L.ai.”
Note: Compressor will recognize source les with or without a le extension (.ai or .wav,
for example).
2 Drag all of the renamed source audio les (not the folder of les) to the batch area.
A new job appears in the batch area, and the Job inspector displays the audio channels that
have been assigned based on their channel codes. (If the Job inspector is not visible, make sure
the job is selected in batch area and the Inspector button is highlighted blue. If you need to
reassign a channel, you can do so by clicking the channel’s icon in the Job inspector.
You can optionally include a video le in the surround sound source le by clicking the Add
Video button in the Job inspector, selecting a video le, and clicking Open.

About audio channels
5.1 channels5.0 channels
Most of the audio settings in Compressor provide mono and stereo (left and right) channel
conguration; some provide additional channel output options, including surround (5.1) channel
conguration. Several of Compressor’s settings oer multiple audio channel congurations:
•
QuickTime Movie settings: QuickTime Movie settings include additional audio channel layouts,
including 3.0, 4.0, and 5.1.
•
Dolby Digital audio settings: Dolby Digital (AC-3) settings include even more audio channel

Chapter 5 Advanced tasks 67
The channel codes describe the location of the channel:
Note: It’s important to understand that Compressor cannot convert stereo audio les into 5.1
surround sound channels. If you want to output a 5.1 surround sound audio le, you must rst
create the six channels of audio required and then import those surround sound les into
Compressor. Then you can use Compressor to output the surround sound source media le. For
more information, see Import and modify surround sound les on page 64.
After you import a surround sound source le, you can transcode that le into any of the channel
layouts above.
Compressor analyzes audio les during import to determine the source le’s channels. When
you apply a transcode setting to the source le, Compressor automatically adjusts the channel
layout of the setting to provide logical results. For many settings, you can choose Automatic from
the “Channel layout” pop-up menu (in the Audio inspector) to have Compressor determine the
logical channel layout based on the source le.
Compressor also maps channels intelligently during output. For example:
•
If you assign a mono channel layout to a stereo source le: The output le will be
automatically downmixed.
•
If you assign a surround channel layout to a stereo source le: The output le will have only left
and right channels—mapped to the left front (L) and right front (R) channels of the source
le—while the other channels are unassigned.
•
If you assign a left front or left rear surround channel to a stereo source le: Compressor maps the
source le to the left channel (and ignores the right channel).
Chapter 5 Advanced tasks 68
Modify an output le’s frame size
Modify frame size overview
Although many of the built-in settings in Compressor contain properties that set the frame size
and aspect ratio of your output video le, you can customize the nal frame dimensions using
the cropping and padding properties in the Video inspector.
Cropping removes video content from an image. If the output le has a dierent aspect ratio than
the output frame size, black borders appear along the top and bottom or left and right sides of
the transcoded le. If the cropped image matches the output frame size, the image will still be
cropped, but no black borders will be seen.
Padding scales the image to a smaller size while retaining the output image’s frame size. Unlike
cropping, padding does not remove any of the source image. Instead, padding squeezes or
shrinks the image to force it to t into a dierent-sized frame. This can be useful for transcoding
les that are stored with incorrect pixel aspect ratios, such as widescreen DV les that are
incorrectly appearing in a non-widescreen format. You can also use the padding controls to
shrink an image and deliberately add black borders around the outside of the image.
Chapter 5 Advanced tasks 69
Crop or pad the video frame
There are multiple ways you can customize the frame size of a source clip during transcoding.
The cropping and padding controls allow you a great degree of exibility and versatility.
Remove part of the source image
To remove part of the original source image, use the cropping controls in the Video inspector.
Depending on the “Frame size” setting (in the Video Properties section of the Video inspector),
cropping may or may not reveal black borders around the edges of your clips.
1 Do one of the following:
•
In the batch area, click an output row to select a setting that’s been applied to a job. With this
method, the modications you make will be used for outputting only that job.
•
In the Settings pane, select a custom setting from the Custom group. (If the Settings pane is
hidden, press Shift-Command-1.) With this method, the modications you make will be saved
to the custom setting for future use.
2 In the inspector pane, click Video to open the Video inspector.
If the inspector pane is not visible, click the Inspector button in the upper-right corner of the
Compressor window.
3 In the Cropping & Padding section of the Video inspector, do one of the following:
•
In the Cropping property, manually type a number in the Top, Bottom, Left, and Right elds to
crop the source image by that many pixels.
•
Choose a preset aspect ratio from the Cropping pop-up menu.
Note: If the aspect ratio you choose does not match the aspect ratio selected in the “Frame
size” pop-up menu (in the Video Properties section), you may see black bars around the edges
of your picture after the le is transcoded.
•
Choose Letterbox Area of Source from the Cropping pop-up menu. This instructs Compressor
to detect the black edges around the image in your source le and automatically enter crop
values to match them. This option is useful if you want to remove the letterbox area (the black
bars above and below a widescreen image) of a source media le.
•
In the preview area, click the Comparison button and position the pointer over the edges
of the frame until the pointer changes to a Crop pointer, then drag inward from the edge to
crop the image.
Note: Cropped edges are visible only on the preview side of the preview area (the right side);
the side of the preview area showing the Source media (the left side) does not display the
crop eect.
Chapter 5 Advanced tasks 70
Force the source image to a dierent aspect ratio
1 Do one of the following:
•
In the batch area, click an output row to select a setting that’s been applied to a job. With this
method, the modications you make will be used for outputting only that job.
•
In the Settings pane, select a custom setting from the Custom group. (If the Settings pane is
hidden, press Shift-Command-1.) With this method, the modications you make will be saved
to the custom setting for future use.
2 In the inspector pane, click Video to open the Video inspector.
If the inspector pane is not visible, click the Inspector button in the upper-right corner of the
Compressor window.
3 In the Cropping & Padding section of the Video inspector, do one of the following:
•
In the Padding property, manually type a number in the Top, Bottom, Left, and Right elds to
pad the source image by that many pixels.
•
Choose a preset aspect ratio from the Padding pop-up menu.
Note: If the aspect ratio you choose does not match the aspect ratio selected in the “Frame
size” pop-up menu (in the Video Properties section), the image may appear squished or
squeezed after the le is transcoded.
•
Choose Preserve Source Aspect Ratio from the Padding pop-up menu. This ensures that
the source clip remains at its native aspect ratio. If the “Frame size” pop-up menu (in the
Video Properties section) is set to a dierent aspect ratio, black borders will be added to the
transcoded output le.
Modify an output le’s frame rate
Frame rate options overview
There are two ways to modify the rate at which a transcoded le plays back. You can apply speed
eects to slow down or speed up playback, or you can change the frame rate of the transcoded
le (which may or may not have an eect on playback speed). If you do change the frame
rate, there are special options for working with interlaced footage, including deinterlacing and
reverse telecine.
The controls that make speed modications are located in the General inspector and in the
Video inspector.
Retime video and audio output
To retime video, you make changes to properties in both the General inspector and the Video
inspector. (You can create some eects by modifying properties in only one of the inspectors.)
The Retiming section in the General inspector allows you to dene a new speed setting for the
clip. You can specify a percentage, such as 50% to create a slow-motion eect or 200% to create
a fast-motion eect; you can identify a precise number of frames and allow the software to
calculate the percentage for you; or you can instruct Compressor to renumber the current frames
into a dierent frame rate in order to convert a le from one frame rate to another without
adding or deleting any frames.
Those settings in the Retiming section are controlled by the settings In the Video Inspector. In
the Video Properties section, you can set a specic frame rate for the transcoded le. By default
this property is set to “Automatic,” which applies the frame rate of the source le to the output
le. Change this setting to create a le with a dierent frame rate from the source.
Chapter 5 Advanced tasks 71
If the source media le contains audio, retiming modies the audio speed as well, thereby
keeping audio and video in sync. Compressor also automatically corrects the pitch so the audio
does not sound articially high or low.
Important: If you modify retiming properties in a setting that uses the QuickTime Movie format
and choose “Copy audio tracks from source” in the Audio inspector, the audio speed is not
changed. Consequently, audio in the output le will not maintain sync with the video.
In the Quality section of the Video inspector you can set the retiming quality. The “Retiming
quality” control species the processing method used when you make changes to any of the
other settings that modify the speed or frame rate of the clip.
Modify timing and frame rate
You can modify the duration of a transcoded le by adjusting controls in the General inspector.
You can modify the frame rate of a transcoded le by adjusting controls in the Video inspector.
Choose a new duration for a transcoded le
1 Do one of the following:
•
In the batch area, click an output row to select a setting in a job. With this method, the
modications you make will be used for outputting only that job.
•
In the Settings pane, select a custom setting from the Custom group. (If the Settings pane is
hidden, press Shift-Command-1.) With this method, the modications you make will be saved
to the custom setting for future use.
2 In the inspector pane, click General to open the General inspector.
If the inspector pane is not visible, click the Inspector button in the upper-right corner of the
Compressor window.
3 In the Retiming section, modify the “Set duration to” property in one of the following ways:
•
Enter a specic percentage of the source footage in the percentage eld, or choose a preset
percentage from the pop-up menu (with a downward arrow).
Note: Selecting a setting from this pop-up menu does not change the frame rate of the
output le. If you want to create a le at a frame rate other than the source’s original rate, you
must change the setting in the Video inspector.
•
Click to select the button next to the timecode eld and enter a specic duration for the
outgoing le. (The percentage eld above will automatically update.)
Note: This option is available only when you are modifying a setting that is part of a job.
•
Click to select the “So source frames play at [frame rate] fps” button.
Note: The frame rate used in this option is the value set in the “Frame rate” property in the
Video inspector.
Chapter 5 Advanced tasks 72
Change the frame rate for a transcoded le
1 Select a setting that is part of a job in the batch area, or select a custom setting in the
Settings pane.
2 In the Video inspector, do one of the following:
•
Choose an item from the “Frame rate” pop-up menu.
Automatic, the default setting, matches the frame rate of the transcoded le to that of
the source le. You can also choose any of several commonly used frame rates, including
23.976 fps, 24 fps, and so on.
•
Type a custom frame rate into the eld to the right of the pop-up menu.
Note: Frame rate conversion can have a subtle or dramatic eect depending on how big a
dierence there is between the original and new frame rates, and also depending on the specic
nature of the footage being converted. Footage with a lot of movement yields a much more
visible change than footage with little movement in the frame. Frame rate conversion may also
add visible artifacts in the transcoded le; from stuttering (sometimes called “juddery”) playback,
to repeated frames, ghost images, or other unnatural-looking elements. These eects can be
somewhat mitigated by adjusting the “Retiming quality” property in the Quality section of the
Video inspector.
3 Select a value from the “Field order” pop-up menu to choose a progressive or interlaced frame rate.
If the current setting does not allow eld order modication, this control remains dimmed.
If you want to convert a le with an interlaced format into a progressive format, see About
deinterlacing on page 73.
Note: The properties in the Retiming section of the General inspector are always aected by the
“Frame rate” property, as well as the “Retiming quality” property in the Video inspector.
About deinterlacing
Video to be played on traditional NTSC or PAL televisions is encoded using an interlaced frame rate.
Each frame is actually made up of two half-frames called elds. Each eld contains half the frame
lines; the odd (or upper) eld contains lines 1, 3, 5, 7, 9 and so on, and the even (or lower) eld
contains lines 2, 4, 6, 8, 10, and so on. When the video is played back, the TV displays the elds in
an alternating pattern, which creates an eective illusion of smooth movement. Viewing interlaced
video on a computer screen that displays both elds simultaneously may reveal a combing eect.
Interlacing creates
a “comb” effect
when viewed on
a computer screen.

You can deinterlace, or remove the elds from an interlaced video clip, by converting it to a

progressive frame rate. The video settings provided in Compressor contain a “Field order” pop-up
menu in the Video inspector that you can use to turn interlacing on or o for the transcoded
le. For more information, see the topic that covers the format you’re using for transcoding, for
example, QuickTime Movie on page 47 or MPEG-2 on page 37.
About reverse telecine
Telecine is the process of converting motion picture lm to the NTSC video format used in
broadcast television. The most common telecine approach to converting lm’s standard 24 fps
frame rate to NTSC video’s 29.97 fps frame rate is to perform a 3:2 pulldown (also known as a
2:3:2:3 pulldown). If you alternate recording two elds of one lm frame and then three elds of
the next, the 24 frames in 1 second of lm end up lling the 30 frames in 1 second of video.

For editing and eects purposes, it’s often desirable to remove the extra elds and restore the
video to its original 24 fps rate. This process is known as reverse telecine. An additional benet of
restoring the original is that it’s easier to convert this to PAL, the European broadcast standard,
which uses a 25 fps frame rate.
The lower frame rate also has the advantage of requiring fewer frames per second of video, leading
to smaller le sizes. The reverse telecine feature in Compressor makes it easy to do this conversion.

Chapter 5 Advanced tasks 74
When using the reverse telecine feature in Compressor, consider these issues:
•
Because of the unpredictable nature of the processing when reversing the telecine,
segmented encoding does not work as eciently as it does when reverse telecine is not
being used.
•
If you pause the transcoding process, the transcode must start from the beginning when you
restart it.
When lm is telecined to NTSC video, it has a constant cadence. This means that the 3:2 pattern
is consistent and uninterrupted. It’s relatively easy to remove the telecine from a constantcadence clip because you need only determine the pattern once.
If you take these telecined clips and edit them as NTSC video, the result is a nal video le that
has a broken cadence with an inconsistent 3:2 pattern. It’s much more dicult to remove the
telecine from such a clip because you have to constantly verify the cadence to make sure you
don’t inadvertently choose incorrect elds when creating the 23.98 fps video.
The reverse telecine feature in Compressor automatically detects broken cadences and adjusts
processing as needed.
Perform a reverse telecine frame rate conversion
1 Do one of the following:
•
In the batch area, click an output row to select a setting in a job. With this method, the
modications you make will be used for outputting only that job.
•
In the Settings pane, select a custom setting from the Custom area. (If the Settings pane is
hidden, press Shift-Command-1.) With this method, the modications you make will be saved
to the custom setting for future use.
2 In the inspector pane, click Video to open the Video inspector.
If the inspector pane is not visible, click the Inspector button in the upper-right corner of the
Compressor window.
3 In the Video Properties section of the Video inspector, choose 29.97 from the “Frame rate”
pop-up menu.
4 In the Quality section of the Video Inspector, choose Reverse Telecine from the “Retiming quality”
pop-up menu.
5 If you’re modifying the setting of a specic job, click Start Batch to begin transcoding.
If you’re modifying a custom setting, there are no additional steps to take.
Chapter 5 Advanced tasks 75
Add video and audio eects
Add and remove eects
Compressor provides a variety of video and audio eects that you can use to improve the quality
of the video and audio in the transcoded le. Video eects modify specic visual aspects of your
source media, such as brightness and contrast, color, noise levels, and interlacing. Audio eects
modify sound aspects in your source media, such as dynamic range, peaking, and equalizer eects.
To add an eect to an output le, you add the eect to a setting and then use that setting to
output your source le. You can view both the source le and a preview of the transcoded le in
the preview area.
Important: As with other properties you add to a setting, eects you add to a built-in setting are
not saved for future use. If you want to save the eects you apply to a setting, you must create a
custom setting by duplicating the built-in setting that contains the eects. For more information,
see Create custom settings on page 21.
Add a video or audio eect
1 Do one of the following:
•
In the batch area, click an output row to select a setting that is part of a job.
•
In the Settings pane, select a custom setting from the Custom area. (If the Settings pane is
hidden, press Shift-Command-1.)
2 In the Video inspector or Audio inspector, choose an item from the Add Video Eect pop-up
menu or from the Add Audio Eect pop-up menu.
If the inspector pane is not visible, click the Inspector button in the upper-right corner of the
Compressor window.
After you choose an eect from the pop-up menu, its adjustable properties appear at the
bottom of the inspector. For detailed information about these properties, see Video eects on
page 77 and Audio eects on page 79. You can apply multiple video and audio eects. When you
add an eect, a checkmark appears beside the eect name in the pop-up menu.
3 Preview eects that you’ve added to a setting by clicking the Play button in the preview area.
Because eects may interact in unexpected ways, be sure to preview the transcoded le each
time you add an eect.
Note: Depending on your system, the source media le type, and the number of eects in the
job, the preview area showing the lter settings may update at a lower frame rate than the
source frame rate.
Change the order in which eects are applied to a source le
Because eects are processed one by one during transcoding—starting with the rst item in the
list—it’s important that you order the eects appropriately. For example, it’s sensible to place a
text overlay eect last in your list of eects so that its text color isn’t modied by other eects.
If you preview the transcoded le and don’t like the results of an eect, you can try reordering
the eects in the eects list to improve the results of the transcoded le.
m Select an eect and drag it to new location in the list of eects at the bottom of the Video or
Audio inspector.
Chapter 5 Advanced tasks 76
Turn an eect o or on
After adding an eect to a setting, you can turn its properties o or on. This can be useful when
previewing an eect.
m Click the blue activation checkbox next to the eect properties. When the checkbox is blue, the
eect is turned on. When the checkbox is black, the eect is turned o.
Remove an eect from a setting
m Choose a checkmarked item from the Add Video Eect pop-up menu (at the bottom of the
Video inspector) or the Add Audio Eect pop-up menu (at the bottom of the Audio Inspector).
The eect’s properties are removed from the list below the pop-up menu.
Video eects
Choose a video eect from the Add Video Eect pop-up menu in the Video inspector:
•
Black/White Restore: Compresses the solid black and white areas (luminance) in the video, such
as backgrounds. This eect can restore nearly black colors to pure black and restore nearly
white colors to pure white without aecting colors in the rest of the image. Drag the sliders to
set the black and white values between 0 and 100. (You can also double-click the values and
type new values.)
•
Brightness and Contrast: Brightens or darkens the overall color and luminance of the video. For
example, use this eect to counteract the darkening to video that some QuickTime codecs can
cause. It’s recommended that you avoid extreme settings, because they can make colors look
washed-out. Drag the sliders to set brightness and contrast values between –100 and 100. (You
can also double-click the values and type new values.)
•
Color Correct Highlights, Color Correct Midtowns, Color Correct Shadows: Correct white balance
inaccuracies and create color eects on the bright, midtone, or dark areas of the video. Drag
the sliders to set red, green, and blue values between –100 and 100. (You can also double-click
the values and type new values.)
•
Fade In/Out: Adds a dissolve and a matte color at the beginning and end of the clip. This eect
has the following properties:
•
Fade in duration/Fade out duration: Enter a time (use a decimal to specify tenths of seconds)
in the text eld to set the duration of the fade-in and fade-out eects.
•
Fade in opacity/Fade out opacity: Drag the sliders to set the opacity of the clip’s video at the
rst and last frames. (You can also double-click the values and type new values.) A value of
0.0 sets the clip video to be completely covered by the matte color; a value of 0.5 sets the
clip to be 50 percent covered by the matte color; and so on.
•
Fade color: Click the color well to set the fade-in and fade-out color.
•
Gamma Correction: Controls the range of brightness in an image. This eect can be used to
remove detail from an underexposed clip or to reduce the saturation of an overexposed clip.
Drag the slider to set gamma values between 0.1 and 4.0. (You can also double-click the value
and type a new value.)
Note: Computers using dierent operating systems have dierent monitor settings. For cross-
platform viewing, correcting the gamma will improve the image for all platforms.
Chapter 5 Advanced tasks 77
•
Noise Removal: Reduces random ecks of noise in the video le, including noise introduced by
codecs. This eect allows you to blur areas of low contrast while leaving high-contrast edges
sharp, creating results that are imperceptible to the human eye but that improve the nal
compression of the transcoded le. The eect’s properties include:
•
Apply to: This pop-up menu sets the channels from which noise is ltered. Choose “All
channels” to lter noise from all channels including the alpha channel. Choose “Chroma
channels” to lter noise from the two chroma channels (U and V) in the YUV color space.
•
Iterations: Choose the number of noise-smoothing passes (between 1 and 4) from this
pop-up menu. For instance, if you choose 2 passes, the noise-removal algorithm is applied to
the media le twice. The le resulting from the of rst pass is used for the second pass, and
so on, so that the more times a pass is performed, the fuzzier the image becomes.
•
Algorithm: Choose a noise-smoothing algorithm from this pop-up menu. Choose Average
to modify each pixel’s color by taking an average of pixels around it, including its own color
value. Choose Replace to modify each pixel’s color by taking an average of pixels around
it, while ignoring its own color value. Choose Merge to modify each pixel’s color by taking
a weighted average of surrounding pixels and itself (with the pixel’s own color value given
greater weight).
•
Sharpen Edge: Sets the contrast around object edges. This eect can counteract the softening
caused by noise removal or blurred source material and increase the perception of sharpness
in the video. However, note that too much of this eect can make video look grainy. Drag the
slider to set sharpening between 0.0 and 100.0. (You can also double-click the value and type
a new value.)
•
Text Overlay: Superimposes text onto the image. The Text Overlay eect contains the
following properties:
•
Position: Choose a position for the text overlay from the pop-up menu, such as Center, Lower
Left, Lower Left–Title Safe, and so on.
•
Alpha: Drag the slider to set the text opacity between 0 (completely transparent) and 1
(completely opaque). (You can also double-click the value and type a new value.)
•
Overlay text: Type text in this eld.
•
Text color: Click the color well to set the text color.
•
Font: Click the Select button to set the font, style, and size.

(completely opaque). (You can also double-click the value and type a new value.)
•
Label: Optionally, type text that you want to appear to the left of the timecode number.
•
Start timecode at 00:00:00:00: Select this checkbox to have the timecode start at zero. When
the checkbox is not selected, the timecode starts at the video’s timecode.
•
Text color: Click the color well to set the text color.
•
Font: Click the Select button to set the font, style, and size.
Chapter 5 Advanced tasks 78
•
Watermark: Superimposes a still image or a movie le onto the video. This eect contains the
following properties:
•
Position: Choose a position for the watermark from the pop-up menu, such as Center, Lower
Left, Lower Left–Title Safe, and so on.
•
Scale by: Drag the slider to set the watermark image’s scaling between 1 (actual size) and 10
(10 times the actual size). (You can also double-click the value and type a new value.)
•
Alpha: Drag the slider between 0 (completely transparent) and 1 (completely opaque) to
adjust the watermark’s opacity. (You can also double-click the value and type a new value.)
•
Repeat: If you are using a video clip for the watermark image, select this checkbox to loop
the playback of the watermark clip throughout the duration of the source le.
•
Watermark: Click the Select button specify a still image or video le to use for the watermark.

the louder parts. This is also referred to as audio level compression. The Dynamic Range eect
contains the following properties:
•
Soften above: Drag the slider to set the level at which audio is reduced (softened) to the level
set by the “Master gain” control (described below). (You can also double-click the value and
type a new value.)
•
Noise threshold: Drag the slider to set the level at which the eect is applied. (You can also
double-click the value and type a new value.) Audio at and above the noise threshold is
dynamically boosted to the level set by the “Master gain” control (described below), and
audio below the noise threshold is not modied.
•
Master gain: Drag the slider to set the average level of the dynamically compressed audio.
(You can also double-click the value and type a new value.)
•
Fade In/Out: Adds an audio fade-in eect at the beginning of the clip and a fade-out at the end
of the clip. The Fade In/Fade Out lter contains the following properties:
•
Fade in duration: Enter a value in the text eld or move the slider to set the length of the
fade in seconds.

the level above which louder peaks are reduced. (You can also double-click the value and type
a new value.)
Add metadata
You can add metadata to your transcoded le in the form of job annotations and
closed-caption les.
Add annotations to a media le
Annotations are output with les transcoded using Apple Devices, MP3, and QuickTime settings.
You can annotate a source media le with information that is important for your workow or
for the person viewing your output le. You can add any of the annotation elds provided in
Compressor, or import metadata that’s used in another media le (like a QuickTime movie).
1 In the batch area, select the job that contains the source le to which you want to add metadata.
Tip: To select the job, rather than an output row under the job, click the source lename at the
top of the job area.
2 In the Metadata area of the Job inspector, do one of the following:
•
Choose an annotation type from the Add Job Annotation pop-up menu.
•
Choose Import from the Add Job Annotation pop-up menu, select a media le that contains
annotations that you want to add to your source le, and then click Open.
3 Type a description in the text eld (or in multiple text elds) for the annotation type you chose.
Chapter 5 Advanced tasks 80
Associate a closed caption le with a source le
Compressor can include a closed caption le (using the Scenarist closed caption format le)
when encoding les with the following formats:
•
QuickTime les: Compressor adds the closed caption le as a closed caption track to the
QuickTime output le. You can view the closed captions using QuickTime Player (version 7.2
or later).
•
MPEG-2 elementary stream les: Compressor embeds the closed caption data in an elementary
MPEG-2 video stream so that it can be used for DVD authoring.
•
MPEG-2 program and transport stream les: Compressor embeds the closed caption data in
program and transport MPEG-2 streams using the EIA-608 ATSC protocol.
Note: The timecode values in the closed caption le must directly relate to the timecode of the
source media le. If you need to see the timecode values in a Scenarist le, try opening it in the
TextEdit application that comes with OS X.
1 In the batch area, select the job that contains the source le to which you want to add closed
captioning information.
Tip: To select the job, rather than an output row under the job, click the source lename at the
top of the job area.
2 In the Metadata area of the Job inspector, click the Choose button in the “Closed captions”
property, select a Scenarist closed caption le in the window that appears, and then click Open.
Set a poster frame
The poster frame is a still image that represents a video or audio media le or a podcast chapter
in applications such as iTunes and in the Finder.
Note: When viewing the output le in iTunes, if no poster frame is set, iTunes automatically uses
the frame 10 seconds from the movie’s rst frame as the poster frame.
Set the poster frame for a job
1 In the batch area, select the job that contains the source le to which you want to set a
poster frame.
Tip: To select the job, rather than an output row under the job, click the source lename at the

m In the preview area, choose Clear Poster Frame from the Marker pop-up menu .
Add markers
Compressor can import and create the following types of markers:
•
Chapter markers: These markers allow easy access to index points throughout a DVD,
QuickTime movie, or video podcast. QuickTime Player can interpret any text track containing
time stamps as a chapter track. Chapter markers can also be linked to artwork and a URL,
which are displayed when a podcast is played.
•
Compression markers: Used for MPEG-2 encoding. These markers identify where Compressor
should generate an I-frame, one type of frame used in a GOP (group of pictures). For more
information, see MPEG-2 on page 37.
•
Edit/cut markers: These markers are used during transcoding to mark frames where MPEG
I-frames should be generated. The I-frames help improve compression quality. Edit/cut markers
are also known as automatic compression markers.
•
Podcast markers: Like chapter markers, these markers can be linked to artwork and a URL.
Podcast markers are usually used to provide a slideshow (with URLs) for users to view when
playing audio podcasts. However, podcast marker names do not appear in the slideshow, and
users cannot navigate to a podcast marker in the transcoded le.
Markers can be output when using settings based on the following formats:
•
H.264 for Apple Devices (For more information, see H.264 for Apple Devices on page 28.)
•
MPEG-2 (For more information, see MPEG-2 on page 37.)
•
MPEG-4, when congured for audio podcasting (For more information, see MPEG-4 on page 42.)
•
QuickTime Movie (For more information, see QuickTime Movie on page 47.)
Important: Although you can set and congure markers for all jobs, only jobs that use the
output le formats listed above will output a le that includes markers.
Chapter 5 Advanced tasks 82
Add a marker to a media le
1 In the batch area, select the job that contains the source le to which you want to add markers.
Tip: To select the job, rather than an output row under the job, click the source lename at the

frame in the source le, enter a dierent timecode value in the viewer that appears at the
bottom of the Marker inspector.
•
File: Uses an image le that you select via the window that appears. To change the image le
after you’ve already added it to the Marker inspector, click Choose, and then select a dierent
image le.
Chapter 5 Advanced tasks 83
Add markers using a chapter marker list
You can create a list of timecode points (using values that match the timecode on the track’s
video clip) and then use that list to create chapter markers.
The le containing the list of timecode points must follow these rules:
•
The list of timecode values must be a plain text le. For best results, create the list with
TextEdit and save the les using the .chp or .txt extension.
•
Each marker must be on a new line that starts with a timecode value in the format 00:00:00:00.
•
After the timecode value, you can include a name for the marker. You can use a space or tab
character to separate the timecode value from the marker name.
•
Any lines that do not begin with a timecode value are ignored. This makes it easy for you to
add comments to the list.
•
The timecode values do not have to be listed in chronological order.
After creating the list, you import it into Compressor:
1 In the batch area, select the job that you want to add markers to.
2 In the preview area, choose Import Chapter List from the Marker pop-up menu .
3 In the window that appears, select the chapter marker le and click Open.

Chapter 5 Advanced tasks 85
Common transcoding workows
Example: Create a le with burned-in timecode
This example describes how to create custom settings, as well as how to add video eects to
your settings through the example of creating a “window dub.” The general idea presented here
can be extrapolated to create custom settings for a wide variety of other workows.
When sending copies of an edited movie to colleagues such as composers, sound mixers, visual
eects artists, and other creative collaborators, it's often useful to add a timecode window visible
in the frame (traditionally called a window dub), so your colleagues can easily reference specic
frames and ensure accurate timing for the work they are completing.
This eect can be created within Final Cut Pro, but Compressor allows you to add the timecode
window at the transcoding stage as well. In Compressor, burned-in timecode (BITC) is added as a
video eect.
Add a timecode window to transcoded video
Because a window dub is not intended to be consumed as nal output, this task will create a
small le suitable for sharing, rather than a high-quality le intended for mastering.
1 In the Settings pane, choose New Setting from the Add pop-up menu .
2 In the dialog that appears, choose QuickTime Movie from the Format pop-up menu, type
“Window Dub” in the Name eld, type “Small H.264 with BITC” in the Description eld, then
click OK.
The new Window Dub setting appears in the Custom area of the Settings pane, and the General
inspector displays the basic properties for the setting. (If the inspector pane is not showing, click
the Inspector button in the upper-right corner of the Compressor window.)
3 In the inspector pane, click Video to switch to the Video inspector.
4 In the Video Properties area, choose “Up to 854 x 480” from the “Frame size” pop-up menu.
5 Click the Change button in the “QuickTime settings” property, and then make the following
changes in the Standard Video Compression Settings window:
a Choose H.264 from the Compression Type pop-up menu.
b In the Motion section, set the Key Frames setting to Automatic.
c In the Data Rate section, click “Restrict to” and enter 1000 kbits/sec in text eld.
Note: If you’re familiar with customizing compression settings, you can modify the setting’s
properties in this window to your liking. Otherwise, leave the rest at their default settings.
6 Click OK.

Tip: TCR is the Industry-standard abbreviation for “Timecode Reader,” and bright yellow is a good
choice because it will show against both dark and light backgrounds. Feel free to experiment
with other settings to suit your particular needs.
The custom setting is saved with the timecode eect applied.
When you apply the Window Dub setting to a media source le, the transcoded output le will
have a timecode stamp burned in.
After you apply this custom setting to a job, you can select the output row in the job and then
further customize the settings for that job by changing the values in the Video inspector. For
example, you can change the location of the timecode numbers, color, font, or other properties
of the job. Changes made to the setting for an individual job will not modify the saved
custom setting.
Tip: This is a great setting to save as a droplet. For more on creating droplets, see Create and use
droplets on page 98.
Example: Convert NTSC or PAL footage to 24p HD
Compressor is capable of extremely high-quality frame rate and frame size conversions that
are superior to the processing that occurs when simply combining dierent footage in a single
project in Final Cut Pro X. Use Compressor to convert your source les to ensure the highest
possible quality.
Create a setting that converts footage from multiple rates and frame sizes to a uniform rate
and size
1 In the Settings pane, choose New Setting from the Add pop-up menu .
2 In the dialog that appears, choose QuickTime Movie from the Format pop-up menu, type
“Convert to 24p HD” in the Name eld, type “Converts any le to 1080/24p” in the Description
eld, then click OK.
The new “Convert to 24p HD” setting appears in the Custom area of the Settings pane, and
the General inspector displays the basic properties for the setting. (If the inspector pane is not
showing, click the Inspector button in the upper-right corner of the Compressor window.)
3 In the inspector pane, click Video to switch to the Video inspector.
4 In the Video Properties area, set the following values:
•
Frame size: 1920 x 1080
•
Pixel aspect ratio: Square
•
Frame rate: 23.976
•
Field order: Progressive
Chapter 5 Advanced tasks 87
5 In the Cropping & Padding area, choose Preserve Source Aspect Ratio from the Padding
pop-up menu.
6 In the Quality area, set the following values:
•
Resize lter: Best (Statistical Prediction)
•
Retiming quality: Best (Motion Compensated)
•
Adaptive details: Select this checkbox.
Note: By setting these properties to the values described, transcoding may take signicantly
longer than if you use the “Better” settings. You might choose to experiment with some
sample les and judge for yourself if you think the quality improvement is worth the extra
transcoding time.
You can apply this custom setting to any type of source footage (any frame rate or size), and the
output will always be a 1080p HD le.
Note: The ultimate quality of the resulting les will be highly dependent on the format and
quality of your source footage.
Example: Create daily review copies of footage
Many multi-day video productions create copies of each day’s footage for distribution to
producers, clients, executives, and others. These clips are called “dailies” or “rushes.” The priority is
to rush to get them done quickly and then notify the recipients that they are available to watch.
This example will show how to use Compressor to generate such review copies for a variety of
distribution methods. The concepts presented here can be applied to creating destinations for
many other workows.
Note: The steps in the tasks below assume you are working with HD source footage.
Create dailies to be hosted on a private server
To create les to be stored on an internal server, or to be uploaded to a web server, follow the
steps below.
1 In the Settings pane, choose New Destination from the Add pop-up menu .
2 In the dialog that appears, do the following:
a Expand the Video Sharing Services group and select Large 540p.
Note: Alternatively, you can choose one of the other settings in this group based on the
bandwidth of the server where you will be hosting the video.
b Choose Send Email from the “Job action” pop-up menu.
c In the Name eld, type “Dailies output.”
d In the Description eld, type “540p output for daily review.”
e Click OK.
The custom destination is added to the Settings pane.
3 Click Locations to open the Locations pane, and then click the Add button .
Chapter 5 Advanced tasks 88
4 In the window that appears, select the folder where you want the video les to be saved, and
then click Choose.
Tip: To avoid unnecessary copying or duplicating of les, select the folder directly on the server
where the videos can be accessed by the intended recipients as soon as transcoding is complete.
The new location is added to the Custom section of the Locations pane.
Note: If you’re uploading to a folder on a web server, you may need to perform additional steps
(such as setting up a script or building an HTML page) to make the videos accessible in a web
browser. Consult your webmaster if you have questions.
5 When you’re ready to generate your dailies, Choose File > Add File (or press Command-I).
6 In the window that appears, navigate to the folder containing the day’s footage, select the le or
les you want to transcode, and then click Add.
Each clip is added as a separate job to the batch area.
Tip: You can also drag les from the Finder into the batch area.
7 Select all the jobs in the batch area, and from the Settings pane, drag the Dailies Output
destination onto any of the jobs.
Dragging to any one of the jobs applies the destination to all selected jobs in the batch area.
8 Switch to the Locations pane and drag the custom location you created in step 4 onto any of the
selected jobs in the batch area.
The location is added to all selected jobs.
9 Select the rst job in the batch area and, in the Action area of the Job inspector, ll in the email
To, Subject, and Message elds.
If the inspector pane is not showing, click the Inspector button in the upper-right corner of
the Compressor window. You can enter multiple email addresses in the To eld, as long as each
address is separated by a comma. Also, be sure to include a link to the location of the saved les
in the Message eld.
10 Select each of the subsequent jobs and repeat step 9, until each job’s Action section in the Job
inspector is lled out completely.
11 Click Start Batch (or press Command-B).
Tip: If you’re transcoding many les to be saved in one location, consider only sending an
email when the last le is completed. That way your recipients won’t receive an email for each
completed le. To prevent emails from being sent, set the Job Action pop-up menu to Do
Nothing for all but the last job in the batch area.
Chapter 5 Advanced tasks 89
Create dailies to be hosted on a third-party website
Some productions may prefer to use a public video-sharing service like YouTube, Vimeo, or
others to host their dailies.
The built-in destinations in Compressor are designed to automatically upload to some of
these sites. However, other sites require creating a custom destination. This example uses a
popular Chinese video-sharing service called Youku. The steps are nearly identical for other
video-sharing services.
1 In the Settings pane, choose New Destination from the Add pop-up menu
2 In the dialog that appears, do the following:
a Expand the Video Sharing Services group and select HD 720p.
b Choose Publish to Youku from the “Job action” pop-up menu.
c In the Name eld, type “Publish to Youku.”
d In the Description eld, type “720p dailies for Youku.”
e Click OK.
The custom destination is added to the Settings pane.
3 When you’re ready to generate your dailies, Choose File > Add File (or press Command-I).
4 In the window that appears, navigate to the folder containing the day’s footage, select the le or
les you want to transcode, then click Add.
Each clip is added as a separate job to the batch area.
Tip: You can also drag les from the Finder into the batch area.
5 Select all the jobs in the batch area, and from the Settings pane, drag the Publish to Youku
destination onto any of the jobs.
Dragging to any one of the jobs applies the destination to all selected jobs in the batch area.
Because Compressor automatically uploads the transcoded les to the video-sharing website
(Youku, in this example), the save location specied in the output row of each job is not
important. For this reason, you can leave the Location set to its default (Source) and then
manually delete the transcoded les on your computer after the jobs are completed.
6 Select the rst job in the batch area, and, in the Action area of the Job inspector, enter your
account information for the video-sharing service, as well as other details about the video clip
(such as title, description, and whether the uploaded le should be stored as private or public).
7 Select each of the subsequent jobs and repeat step 6, until each job’s Action section in the Job
inspector is lled out.
8 Click Start Batch (or press Command-B) to begin transcoding.
Note: In this workow, Compressor can’t automatically send an email to notify the recipients that
the les are available, so you’ll have to do that manually after the jobs are completed.

Customize keyboard shortcuts
View keyboard shortcuts in the Command Editor
Compressor provides a wide variety of menu commands and keyboard shortcuts that let you
control almost every aspect of your transcoding workow. You can use the Command Editor to
modify existing shortcuts, create new shortcuts, and save multiple sets of keyboard shortcuts
that you can export for others to use. You can also import a set of shortcuts that someone else
created. And if you’re more familiar with keyboard shortcuts from other applications, you can use
the Command Editor to substitute those shortcuts in place of the default set for Compressor.
The Command Editor provides a set of keyboard shortcuts for Compressor in English, Japanese,
French, and German. The language that is shown is determined by your computer’s operating
system. To learn how to change the language used by Compressor, see OS X Help, available from
the Help menu when the Finder is active.

Transcode Final Cut Pro and Motion projects using Compressor
If you have Final Cut Pro X or Motion 5 installed on the same computer as Compressor 4.1, you
can send sequences or clips from Final Cut Pro or Motion directly to Compressor for transcoding.
Transcode a Final Cut Pro or Motion project using Compressor
Do one of the following:
m Send a project from Final Cut Pro to Compressor: Select the project and choose File > Send
to Compressor.
m Send a project from Motion to Compressor: Open the project and choose Share > Send to Compressor.
Note: You can also drag a Motion project le to the batch area in Compressor.
For more information about using Compressor settings in Final Cut Pro, see Final Cut Pro Help.
For more information about using Compressor settings in Motion, see Motion Help.
After the Final Cut Pro or Motion le appears in Compressor as a source le in a job, you can add
a setting and other information to the job’s output rows and then transcode the batch.
Enable one or more instances of Compressor
You can increase the processing power of a single computer, and thus reduce the time it takes to
process batches, by enabling one or more additional instances of the Compressor application.
3 Select the “Enable additional Compressor instances” checkbox, then choose a number of
instances from the pop-up menu.
The number of instances available in the pop-up menu changes automatically based on the
amount or RAM and number of CPU cores in your computer. It’s recommended that you rst
enable all the additional instances, transcode several test batches, and then, if performance is
slow, decrease the number of instances to use fewer of your computer’s resources. You can use
the Activity Monitor application in OS X to determine how of your CPU is being used.
Note: If the computer has a hardware encoder, and if you enable multiple instances of
Compressor, the time it takes to process a batch can potentially increase, because the hardware
encoder can only be used with single-pass, nonsegmented jobs. If you nd that processing time
has increased signicantly, turn o additional Compressor instances by deselecting the “Enable
additional Compressor instances” checkbox.
