Using this Guide
This guide introduces you to Avid Xpress. It presents the essential features of the system; most chapters also contain hands-on tutorial
sections so you can practice what you learn.
Using the Tutorial
The self-paced tutorial sections included in this guide are designed as
guided Avid edit sessions using the basic features of the Avid Xpress
system. In the tutorial sections, youÕre going to edit a one-minute
sequence about a company in Amesbury, Massachusetts that makes
small Þshing boats called dories.
The footage for the sequence is on the Tutorial CD-ROMs that came
with your system. They contain digitized media that is ready for you
to use.
The instructions in this tutorial take you through each step of the edit
process:
¥Starting a project (in Chapter 3
¥Getting ready to edit (in Chapter 5)
¥Editing a rough draft (in Chapter 6)
¥ReÞning the edit (in Chapter 7)
¥Adding effects, titles, and other Þnishing touches to the sequence
(in Chapter 8 and Chapter 9)
¥Preparing output (in Chapter 10)
¥Backing up (in Chapter 11)
This tutorial assumes a basic familiarity with the Macintosh¨ computer. If you have never used a Macintosh system, please refer to the

What Y ou Need
The CD-ROMs packaged with your Avid Xpress system include all
Þles necessary to do this tutorial:
¥Read Me First Þle Ñ contains the installation instructions for each
of the Þles on the CD-ROMs. These instructions also appear in
ÒInstalling the Avid Xpress Tutorial FilesÓ on page 17.
¥MediaFiles folder Ñ contains the digitized Þles you need for the
tutorial. You need to copy these Þles onto your external media
drive.
¥Composer Projects folder Ñ contains the project and bins you
need for the tutorial. You need to copy these Þles onto your Avid
drive.
Turning on Your Equipment
Begin your edit session by turning on the various components of your
Avid Xpress system. If any part of your system fails to turn on, make
sure its electrical cord is plugged snugly into an appropriate electrical
outlet or power strip. See the Avid Media Composer Products Setup Guide
for information on setting up your system.
c
If you fail to follow the proper sequence for starting up your system,
you could damage your Macintosh computer and/or storage drives.
Always turn on the devices as follows:
1. Fixed-storage drives: Turn on Þxed-storage drives before starting
the computer. Allow 10 to 15 seconds for the drives to spin up to
speed before starting the Macintosh.
2. Other peripheral hardware: Turn on all other peripheral units
except the Macintosh. This includes:
(switcher, time-base corrector, and so on) if you plan to digitize or conduct an autoassembly.
¥Digidesign¨ audio interface hardware, if your system
includes these. Turn on the Digidesign hardware and black
burst generator in order to maintain proper sync between
audio and video while digitizing and editing.
n
For information on
Macintosh features,
such as the desktop and
icons, see your
Macintosh documentation.
The black burst generator that accompanies the Digidesign hardware should
already be turned on if it is connected to an active power strip.
3. The Macintosh: Press the Power On key located at the upper right
corner of the keyboard.
When you start the Macintosh:
¥You hear a tone that means the hardware is operational.
¥The computer goes through a self-check routine. If the
Macintosh passes all of its internal logic tests, the smiling
Macintosh icon appears.
¥The Avid startup screen appears and the initialization process
begins.
16
¥The Macintosh desktop appears.
c
To avoid damage, do not disconnect or turn off hard disks or individual disk drives while the Macintosh is on.
Installing the Avid Xpress Tutorial Files
The Avid Media Composer Products CD-ROM contains all of the Þles
you need for the tutorial sections of this guide. It takes about 30 minutes to copy the media Þles from the CD-ROM to the external hard
drive. You need to have approximately 970 MB of free space on your
external hard drive to accommodate the media.
The CD-ROMs contain several versions of the tutorial media Þles digitized at different Avid Video Resolutions (AVRs). You need to use AVR
70 for Avid Xpress. You also need to have approximately 110 MB of
17
free space on your external hard drive to accommodate the media. The
tutorial Þles for AVR 70 require two CD-ROMs for NTSC and two for
PAL. The procedure is the same for installing either type.
To install the tutorial Þles for AVR 70:
1. Insert the CD-ROM labeled Avid Media Composer Products
Online Tutorial (PAL) Disk 1 or Avid Media Composer Products
Online Tutorial (NTSC) Disk 1 and double-click its icon.
2. Double-click the folder at the top level.
You should see two folders labeled Composer Projects and
OMFI MediaFiles.
3. Do one of the following:
¥If there is an existing OMFI MediaFiles folder on the external
media drive, open the OMFI MediaFiles folder on the CDROM, choose Select All from the Edit menu, and drag the contents to the OMFI MediaFiles folder on the external media
drive.
¥If there is no existing OMFI MediaFiles folder on the external
media drive, drag the OMFI MediaFiles folder from the CDROM to the external media drive.
The Þles are loaded on the drive.
4. Do one of the following:
¥If there is an existing Composer Projects folder on the Avid
drive, open the Composer Projects folder on the CD-ROM and
18
drag the Boat Shop folder to the Composer Projects folder on
the Avid drive.
¥If there is no existing Composer Projects folder on the Avid
drive, copy the Composer Projects folder on the CD-ROM to
the Avid drive.
5. Eject the CD-ROM in the drive.
6. Insert the CD-ROM labeled Avid Media Composer Products
Online Tutorial Disk 2 and double-click its icon.
7. Double-click the top folder.

CHAPTER 2
About Avid Xpress
Welcome to the world of nonlinear digital video editing, in which you
can create professional-quality video programs from your desktop.
Avid Xpress allows you to change any part of your video program at
any time, until you create your Þnal program on tape. With Avid
Xpress, you can be as ßexible and as creative as possible when editing
your video programs.
This chapter explains the basic concepts and terminology that you
need to be familiar with to edit video with Avid Xpress.
Video Editing with Avid Xpress
In traditional video editing, you electronically copy video from a
source tape to an edit master tape. The process is tedious, and changes
are difÞcult to make.
By contrast, when you edit with Avid Xpress, you donÕt have to dub
footage onto a master videotape. Instead, you manipulate Avid Xpress
ÒclipsÓ that reference your digitized audio and video material. This
allows you to experiment with every edit you make through multiple
generations. You can trim, move, delete, duplicate, or modify individual frames or entire segments, and immediately see the results.
24
When you play back your work, the system accesses and plays the
appropriate portions of the digitized video and audio.
The following is a summary of the Avid Xpress editing process:
1. Collect source material for your project
Collect your source video and audio. You can start with any video
format Ñ Beta SP, 3/4 inch, 8mm, Hi 8, VHS, S-VHS, or any other.
You can also incorporate still images or other computer-generated
Þles, including computer graphics, still-image Þles, animations,
sound effects, or QuickTime¨ movies.
2. Digitize your source material
Play your source videotapes on a video deck, and digitize them
right onto your hard disk. Import computer-generated Þles into
your project Ñ graphics, still images, animations, sound effects,
synthesized music, QuickTime movies, and special effects.
3. Create a rough cut of your video
Play your digitized source material in Avid Xpress. Organize your
sources, and lay out a storyboard using representative clip frames.
Mark sections of your digitized sources, and edit them together.
Reorder your material, cut and paste sections, and trim the transitions between shots. Immediately view each change you make.
Save the changes that you like; easily undo the changes that you
donÕt like. Experiment!
4. ReÞne your edits
Use Avid Xpress to enhance your program with special effects,
such as dissolves, wipes, Þlters, and video overlays. Add graphics
and animations, CD-quality sound, and a voice-over. Incorporate
titles and credits.
5. Record your Þnished program
Record your Þnal program from Avid Xpress onto videotape. Save
a copy of your program in QuickTime format for CD-ROM or network distribution. Modify and record a new version of your program at any time.
25
Avid Xpress Essentials
This section explains the terms and concepts that you will need to
know in order to understand the Avid Xpress editing process.
Media Files
Material is stored in
media Þles.
Clips
When you digitize source material from a video or audio deck, or
when you import computer graphic Þles into your Avid Xpress
project, the material is saved in media Þles on your systemÕs external
hard disk. One media Þle is created for each track of video or audio.
Three media Þles Ñ for one track of video and two tracks of audio Ñ
are created for a video with a stereo sound track.
PowerPC
Video deck
OMFI MediaFiles
Media drive
Master clips
Clips point to media
Þles.
You do not manipulate media Þles directly. Avid Xpress creates
another Þle, called a master clip, on your systemÕs internal disk when
you digitize media. The master clip is simply a pointer into its corresponding media Þle.
26
Subclips
While editing your video, you create other clips, such as graphic clips
and effects clips. You make your edits by modifying clips Ñ the corresponding media Þles remain unchanged. This allows you to easily create and undo edits without destroying your original material.
Because you work with clips instead of media Þles, you can create virtually unlimited versions of a program without creating multiple copies of the extremely large source material.
Subclips are sections
that you mark within
clips.
Sequences
Subclips are speciÞc sections of clips that you want to use in your program. You create a subclip by marking IN and OUT points in a clip
and then dragging this material to the bin. The subclip is composed of
the material between the IN and OUT points.
Clip
Subclip
A subclip points to a media ÞleÕs master clip. You must not delete the
master clip from which a subclip was created. If you delete the master
clip, you will lose the information in the subclip.
A sequence is a program created from one
or more clips and subclips.
You can join different clips and subclips to create a sequence. A
sequence can include edited material from source clips and subclips,
new clips created when you add effects during the editing process,
27
and material from other sequences. Your Þnal program will be composed of one or more sequences, depending on how itÕs most convenient for you to work.
Clip
Subclip
Sequence
Sequence in Timeline
Invisible frame
Visible frames
A sequence is composed of marked material from clips, subclips, and
other sequences. The material outside the IN and OUT points is invisible in the sequence. This invisible material is very important, because
you need it to trim cuts and create transition effects between segments.
See ÒTrimmingÓ on page 110 for more information about trimming
cuts. See the Avid Xpress Effects Guide for information about creating
transition effects.
Like a clip, a sequence contains pointers to media Þles. If you delete
one of the clips used to create a sequence, the sequence still works,
because the sequence contains its own pointers to the media Þles.
28
Sequence
Clip
Your Program
The program is your
Þnal video creation.
Bins
You organize your footage in bins.
Subclip
OMFI MediaFiles
A program consists of one or more sequences. You use clips, subclips,
and sequences to build a program. Your program is represented by the
Timeline. A program is your Þnal creation; you can output your program to tape when you are Þnished.
Even though your media Þles contain the actual source material for
the program, you never manipulate the media Þles directly. Instead,
you move, copy, and edit clips, subclips, and sequences.
Clips, subclips, and sequences are organized and stored in bins. Traditionally, a bin is a place where Þlm editors store reels of Þlm. In Avid
Xpress, bins are tools for organizing the material for a project.
Your Project
You edit within a
project. A project consists of one or more
bins, normally containing footage for a speciÞc
program.
You gather the material you need to create a program in a project. Each
project contains information about bins, clips, subclips, sequences, and
the program in the Timeline. You may have several projects on your
system, but you can only work on one project at a time.
29
The Attic Folder
Avid Xpress saves copies of your current project and its bins at a regular interval and whenever you save or close a project or bin. These
auto-save Þles are stored in the Attic folder in the Avid Xpress application folder. If at any time you lose work due to a power outage or system error, open the Attic folder and look for a project or bin of the
same name with the sufÞx .bakxx, where xx is the version number. For
example, the Þrst backup Þle for the bin Skaters would be named Skaters.bak01. Later versions would be named Skaters.bak02, Skaters.bak03, and so on.
The Avid Xpress File System
The following illustration shows the different kinds of Avid Xpress
Þles and where they are stored. Media Þles must be stored on an Avidapproved media drive, which is guaranteed to be fast enough to support real-time video.
30
The Avid Xpress application folder can be stored either on your computerÕs internal drive or on an external drive. It is common practice to
install it on the internal drive, as it is shown in the following illustration. The Composer Projects folder is stored on the same disk as the
Avid Xpress application folder.

CHAPTER 3
Starting a Project
The Project window provides controls in three different display modes
for structuring and viewing important information about your current
project. These include a display of bins and folders associated with the
project, a list of all settings, and basic information about the format of
the project and use of system memory.
The overview topics are described in the following sections:
¥About Composer Projects and Avid Users Folders
¥Using the Bins Display
¥Using the Settings Display
¥Using the Info Display
Tutorial: Starting a Project contains the following sections:
¥Starting the Application
¥Opening a Project
32
About Composer Projects and Avid Users Folders
Composer Projects and Avid Users folders allow you to move whole
projects or selected project and/or user settings between systems by
copying and moving Þles on your desktop.
When you create a new project or user, the system creates the following Þles and folders:
¥When you create a new user, the system creates three items: a user
proÞle Þle, a User settings Þle, and a user folder containing the
two. Each item is given the user name you provide. This new
folder is stored in the Avid Users folder on the Avid drive.
¥When you create a new project, the system creates three items: a
project Þle, a Project settings Þle, and a folder containing the two,
each of which is given the project name you provide. This new
folder is stored in the Composer Projects folder on the Avid drive.
Your settings are initially set to the default values. As you work, the
Þles maintain current settings, while the project folder Þlls with bin
Þles.
33
Using the Bins Display
Bins are windows that storetitles, Òthumbnails,Ó and information
about the materials you digitize. These editable Þles are called master
clips. They refer to the actual media Þles created when you digitize
source material. While the physical media are stored on external hard
drives, the master clips that refer to that media reside in the bin. Bins
also store the sequences, subclips, group clips, and effect clips that you
create during a project. The Project window allows you to make a new
bin, close it, reopen it, and move clips among these bins. You can also
open bins created for different projects.
After you select a user and project in the Project Selection dialog box,
the Project window opens. To view a complete list of bins associated
with the project, click the Bins button in the Project window. A scrolling list appears.
Bins button
Open bin
From the Bins list you can examine the number, names, size, and location of bins, and you can also open bins. Dotted bin icons next to bin
names indicate bins that are currently open; solid icons indicate closed
bins.
34
Using the Settings Display
From the Settings display you can view, select, open, and alter various
User, Project, and Site settings, as described in this section.
To view the Settings display, click the Settings button in the Project
window.
Settings button
Settings type
About Settings
Three types of settings are displayed in the Settings scroll list, as indicated in the third column of information: User, Project, and Site
settings.
¥User settings are speciÞc to a particular editor. In general, User
settings reßect individual preferences for adjusting the way you
view Avid Xpress. Individual User settings are stored in each user
folder within the Avid Users folder on the Avid hard drive.
35
¥Project settings are directly related to individual projects. When a
Project setting is changed, it affects all editors working on the
project. SpeciÞc Project settings are stored in each project folder
within the Composer Projects folder on the Avid hard drive.
¥Site settings establish default parameters for all new users and
projects on a particular system. These can apply to particular conÞgurations of equipment installed at the site, for example, spec
and node settings for an external switcher. They can also include
other user or project settings that you copy into the Site Settings
window. Site settings are stored in a separate Settings folder in the
Avid Xpress folder on the Avid hard drive.
Reviewing Basic Settings
For a complete description of all settings and
their options, see the
Avid Media Composer
Products Reference.
The following list describes basic system settings to review at the start
of your project:
¥Bin settings
¥General settings
¥Interface settings
Double-click each setting in the Settings scroll list of the Project window to view the following dialog boxes:
¥Bin settings deÞne general system functions related to bins,
including:
-Parameters of the Auto-save function
-Maximum number of bin backup Þles stored in the Attic
folder
¥General settings deÞne fundamental system defaults, including:
-Starting timecode for sequences edited in Avid Xpress
-Setup default for either American NTSC or Japanese NTSC
video input (affects calibration)
36
-Whether the system uses the drive-Þltering function to auto-
matically target only the fastest drives when digitizing highresolution media
¥Interface settings determine the level of basic information dis-
played in the interface, including whether written labels are displayed beneath icons in the various command palettes.
Using the Info Display
The Info display in the Project window allows you to view basic
project information, such as the video format (NTSC, for example) or
frame rate.
To activate the Info display, click the Info button in the Project
window.
Info button
Fast Menu button
The items listed in this view are for information only and cannot be
changed from the Info list.
To see additional information:
1. Click the Fast Menu button at the bottom of the Info window.
A pop-up menu appears.
37
2. Choose one of the options from the pop-up menu. See ÒInfo
display of project informationÓ in the online help index for more
information about these options.
About Projects and Memory
The way a project uses memory has a direct effect on performance. As
a project develops, the number of media objects in use (clips, effects,
and other bin items) increases. Because the system keeps track of them
in RAM, they can be played back faster, but the memory requirements
can slow down the system in other ways.
The AvidXpress Release 2.0 Release Notes provide information about
system requirements for RAM. Occasionally you might need to adjust
the way your Macintosh uses its RAM in order to work efÞciently.
There are two factors that can affect the performance of your system:
¥If you opened and quit several applications during a session, or if
you opened and closed various Avid Xpress tools repeatedly, your
computerÕs memory may become fragmented. As a result your
system may be sluggish. To solve this problem, close all applications and restart your Macintosh.
n
¥If you need to open more or larger Þles within Avid Xpress, you
might want to increase the amount of memory allocated to the
application from the desktop.
To check and adjust the allocation of system memory (RAM), consult your
Macintosh documentation.
38
Viewing Memory
To view how Avid Xpress is using the system memory, choose
Memory from the Info window Fast menu. Also see the Avid Xpress Release Notes for information about memory requirements.
If the memory in use is already near the limit of the total memory, you
might want to consolidate Þnished elements and eliminate old material from the project, or break the project up into separate, segmented
projects. For more information on consolidating, see ÒConsolidatingÓ
in the online help index.

Digitize Preparations Check List
1. Check your hardware conÞgurations: power switches, cable connections, pull-down switch on the Video Slave Driver, and remote
switch on the source deck for deck control (see the Avid Media Composer Products Setup Guide for hardware conÞgurations).
2. In the Project Settings scolling list, make sure you have the desired
options selected in the General Settings, Deck Settings, Deck Preferences, Deck ConÞguration, and Digitize Settings dialog boxes.
3. Consider striping your drives in advance according to the
AVIDdrive Utility UserÕs Guide if you are working on a complex
project with multiple streams of video and high-resolution
images.
4. Insert a tape into the deck and set up the Digitize Tool for track
selection, target bin, target drives, source tape, and source deck.
5. Set up the Compression Tool for resolution (AVR) and color
compression (see ÒCompression ToolÓ in the online help index).
6. Use the Audio Tool to set the audio input levels.
7. Use the Video Input Tool to set the video input levels; save your
video settings for future use.
50
Digitizing
You can digitize your source material in one of the following ways:
¥Digitize and log at the same time
¥Batch digitize
¥Redigitize
¥Use Avid MediaLog and import shot logs
Digitizing and Logging at the Same Time
When you digitize without entering log information in a bin ahead of
time, the system creates clips and associated media Þles while you digitize. Digitizing in this manner involves manually cueing source footage with an Avid-controlled deck using the deck controls in the
Digitize Tool.
See ÒDigitizingÓ in the
online help index.
There are several ways to digitize and log at the same time:
¥Digitizing from a mark IN to a mark OUT. This method lets you
specify the exact timecode location to begin and end digitizing.
You can also specify only a mark IN or mark OUT, and enter the
other mark on-the-ßy.
¥Digitizing on-the-ßy. This method is easier than setting marks,
but it is more imprecise. It involves using the deck controls in the
lower left corner of the Digitize Tool to cue, play, and stop the
source footage manually while digitizing.
¥Autodigitizing. This method requires the least amount of supervi-
sion and effort, but usually calls for more digitizing time and disk
storage space. It involves playing each source tape from a cue
point near the beginning and letting the system digitize the entire
tape, automatically naming and entering each long clip into the
bin.
51
Batch Digitizing
Redigitizing
Once you have imported a log or manually logged a group of clips
into a bin, you can automate the digitize process by using the Avid
Xpress batch digitizing capabilities. In order to batch digitize, source
tapes must have timecode. For more information and procedures, see
ÒBatch digitizingÓ in the online help index.
Redigitizing is the process of capturing previously digitized source
footage based on existing clips and sequences. Redigitizing uses the
batch digitize process and does not require extra logging time because
the clip information for such things as source tracks, timecodes, and
compression settings already exists in the bin. For more information
and procedures, see ÒRedigitizingÓ in the online help index.

CHAPTER 5
Getting Ready to Edit
To get ready to edit, you need to understand how to organize your
clips and manipulate them. The overview is in the following sections:
¥About Bin Display Modes
¥Controlling Playback
¥Marking IN and OUT Points
¥Creating Subclips
Tutorial: Getting Ready to Edit contains the following sections:
¥Viewing Clips
¥Playing Clips
¥Marking Edit Points
¥Subclipping
53
About Bin Display Modes
You can use two display modes for viewing and working with clips in
a bin: Text mode and Frame mode.
The Bin Fast menu displays the same menu as
the Bin menu on the
toolbar along the top of
your screen.
Column headings
Object icons
Bin Fast menu
Frame mode
¥In Text mode, clips are displayed in a database text format using
columns and rows, with icons representing the various objects.
You can save various arrangements of columns, text, and objects
as customized views by using the Bins settings in the Project window and the Bin Fast menu.
Text mode
To enter Text mode, click the Text Mode button (labeled T) in the
lower left portion of the bin.
¥In Framemode, each clip is represented by a single picture frame,
with the name of the clip. You can play back the footage in each
frame, change the size of frames, and rearrange frames in any
order within the bin.
54
To enter Frame mode, click the Frame Mode button (labeled F) in
the lower left border of the bin.
Controlling Playback
There are several ways to play, view, and cue clips:
¥Instantly access frames or move through footage by using the posi-
tion indicator within the position bar under the Source pop-up or
Composer monitors
¥Play, step (jog), or shuttle through footage by using buttons
¥Play, step, or shuttle by using keyboard equivalents
Using Position Bars and Position Indicators
You can quickly access frames within a clip thatÕs been loaded into a
monitor or move through the footage by using the position indicators
that appear in the position bars under the Composer or Source pop-up
monitors, and in the Timeline when you are viewing a sequence.
¥You can move the position indicator within the position bar under
the Composer or Source pop-up monitors by clicking anywhere in
55
Position bar

¥In the Timeline, the position indicator shows your position within
the position bar, or by dragging the position indicator to the left or
right. The speed with which you drag the position indicator determines the speed at which you move through the footage.
the sequence. It is always in the same position as the position indicator in the Composer monitorÕs position bar, and works in the
same way: you can click anywhere in the Timeline to relocate the
position indicator, or you can drag the position indicator through
footage at varying speeds.
Position indicator in Timeline
Using Buttons
¥You can go directly to the beginning or end of a clip or sequence
by clicking at the far left or far right of the clip or sequence.
You can use the buttons that appear below the Composer and Source
pop-up monitors to play and step through your footage. You can also
use the keyboard to manipulate footage.
56
Play, Fast Forward, and Rewind Buttons
The Play, Fast Forward, and Rewind buttons work much like the buttons on any conventional VCR. With a clip loaded in a monitor, the
Play button plays your footage at a normal rate. The Fast Forward and
Rewind buttons instantly cue you to the beginning or the end of the
clip.
The Play button appears by default in the buttons below the Composer and Source pop-up monitors. The Rewind and Fast Forward
buttons appear in the Tear-off palette.
n
Video Monitor buttons
Audio Monitor buttons
Step Buttons
During playback, the Play button also acts as a Stop button.
When viewing sequences in the Composer monitor, you can play only
video and audio tracks that are currently monitored in the Track
Selector panel.
Track Selector panel
For more information, see the online help index.
You can also use the Step buttons under either monitor to jog or play
the clip backward or forward in 1-frame increments.
If you press and hold the Option key while clicking either button, you
can advance ten frames forward and ten frames backward.
57
Using the Tear-Off Palette
The Tear-off palette provides additional buttons for editing and
navigating.
You can view the Tear-off palette by pulling down the Fast menu
under the Composer monitor. Hold the mouse and drag the palette to
any other location on the screen for handy access.
Using the Keyboard
The default keyboard contains all of the buttons discussed so far.
Step buttons
Play button
Stop button
J-K-L Keys (Three-Button Play)
The J-K-L keys on the keyboard allow you to play, step, and shuttle
through footage at varying speeds. This feature, also referred to as
Play/Step/Shuttle buttons
58
Home key
End key
three-button or variable-speed play, allows you to use three Þngers to
manipulate the speed of playback for greater control.
To shuttle through the footage using the J-K-L keys on the keyboard:
1. Load a clip or sequence into the Source pop-up or Composer
monitors.
2. Use the following keys to shuttle at varying speeds:
¥Press the L key to move forward through the footage at nor-
¥Press the J key to move backward at the same shuttle speed
¥Press and hold the K and L keys together for slow forward.
¥Press and hold the K and J keys together for slow backward.
3. To pause the shuttling, press the K key.
4. To stop shuttling, press the space bar.

increments.
You can also use the Home, End, and arrow keys on the keyboard to
move through footage when a clip is loaded in a monitor.
¥The Home key takes you to the beginning of a clip or sequence.
¥The End key takes you to the end of a sequence.
¥The Left Arrow key moves the footage one frame forward.
¥The Right Arrow key moves the footage one frame backward.
59
Marking IN and OUT Points
You can mark IN and OUT points for your clips in advance, which
provides several advantages:
¥You can quickly build a sequence by splicing the marked clips into
place one after another.
¥You can use the process of rough-cut or storyboard editing, which
allows you to instantly splice several prepared clips into a
sequence (see ÒStoryboardingÓ on page 102).
¥You can play back and mark clips in the bin before loading a single
clip, saving several steps.
Even if your marks are not accurate now, Avid Xpress allows you to
trim the edit points and Þne-tune the sequence later without reediting
the material.
Creating Subclips
When you mark footage with IN and OUT points, you can either save
the entire clip along with the new marks, or you can create subclips
based on the marks you set to break up longer master clips into
smaller segments of selected footage.
You can also create subclips while digitizing, as
described in ÒSubclips:creating on-theßyÓ in the online help.
This is similar to creating selects of all your best footage before editing.
Unlike selects, however, subclips do not directly reference the original
media. Subclips remain linked to the master clips from which they are
created, and the master clips in turn reference the digitized media Þles
located on your storage drives. As a result, none of the original footage
is lost.
You can create subclips directly from the marked section of material in
the monitors by using one of the following methods:
60
¥Option key: Press and hold the Option key, then drag the picture
from the monitor to the bin in which you want to store the subclip.
¥Subclip button: Click the Subclip button located on the Tear-off
palette to create the subclip and place it into the active bin by
default. If you press the Option key while you click the Subclip
button, a dialog box allows you to choose the destination bin for
the subclip.
The new subclip is listed in the bin, preceded by a subclip icon and
identiÞed with a numbered .Sub sufÞx, as shown in the following
illustration.
For more information
on trimming, see ÒTrim
editsÓ in the online help
index.
Subclips do not limit your access to the original, digitized master clip
material when trimming. Therefore, if you must trim beyond the
marked IN to OUT boundaries of the subclip to make it longer or
shorter, your system does accommodate the boundary adjustments
during the trim.
61
Tutorial: Getting Ready to Edit
The following tutorial steps correspond to the clips and sequence in

Now mark the IN and OUT points for the ducks clip. This time,
instead of using the 5 key, use the J-K-L keys to play the clip.
1. Double-click the ducks clip to activate it.
2. Locate the frame where the second duck enters the right edge of
the frame behind the duck swimming in the foreground.
Use the 3 and 4 keys to locate the precise frame.
3. Mark an IN point by pressing the I key.
A white sawtooth pattern appears on the left edge of the Mark IN
frame.
4. Step forward to locate the Þrst frame where the same duck ßies
beyond the left edge of the screen.
69
5. Mark an OUT point by pressing the O key.
A white sawtooth pattern appears on the right edge of the Mark
OUT frame.
Marking the
draw knife cu
LetÕs mark another clip weÕll use in the sequence.
1. Display the draw knife cu in the Source pop-up monitor by double-clicking it in the Getting Ready to Edit bin.
When you edit the sequence, you want to show just three strokes
of the knife.
2. Place the position indicator around the midpoint of the clip, and
play forward until just after the Þrst fairly large wood chip falls
off.
Use the Play button (or J-K-L keys) to get close to the frame, and
then use the Step buttons to locate the frame you want to use as
your IN point.
3. Mark an IN point by clicking the Mark IN button under the
monitor.
A white sawtooth pattern appears on the left edge of the Mark IN

5. Mark an OUT point by clicking the Mark OUT button under the
monitor.
A white sawtooth appears on the right edge of the Mark OUT
frame.
70
Using Timecode to Find a Frame
You can mark IN and OUT points by using timecode as your reference
point. If you know the timecode for the frame you want to mark, you
can go to that frame instantly by typing it on the numeric keypad.
In this section, you will use visual cues to mark an IN point, and then
locate a speciÞc timecode. First, you need to display the appropriate
timecode information.
1. Double-click the chiseling clip to open it.
2. Place the cursor in the gray title bar area over the timecode information displayed above the Source pop-up monitor.
3. When the cursor changes to a downward arrow, click to display
the pop-up menu, then choose TC, V1 (timecode for track V1)
from the menu. A checkmark means it is already selected.
Timecode shows the following:
Hours
Minutes
Seconds
Frames
One second holds 29 frames.
The timecode references the frame displayed in the Source popup monitor.
4. Use the Play and Step buttons to locate the frame where the boatbuilder begins one of the Þrst strokes of the chisel.
71
5. Click the Mark IN button.
6. Read the timecode in the Timecode display at the IN point. Add 15
frames (13 frames PAL) to the timecode number. (Remember,
there are 29 frames in a second.)
For example, if the timecode is 04:11:34:15, adding 15 frames gives
you a result of 04:11:35:00.
7. Type the resulting number on the numeric keypad and press Enter
on the numeric keypad. The system inserts the colons for you.
As you start typing, a window opens in the middle of the Source
pop-up monitor, showing the numbers you type. When you press
Enter, the position indicator locates the speciÞed frame.
The Timecode window displays the current number.
n
To locate frames using the numeric keypad, you must show the appropriate
timecode in the Timecode display. For example, the timecode display must
show track V1 to go to a speciÞc frame on the V1 track.

8. Click the Mark OUT button.
72
Using Frame Offset
Whenever you use the
numeric keypad, you
must press Enter after
typing the number.
When using frame offset, type one frame less
than the number of
frames you want to
advance.
You can also use the numeric keypad to move the position indicator
forward or backward a speciÞed number of frames, with the frame offset feature. LetÕs mark an IN point for the planing cu clip and then use
frame offset to locate the OUT point.
1. Double-click the planing cu clip to open it.
2. Click in the Source pop-up monitor to activate it.
3. Use the Play and Step buttons to locate the frame where the boatbuilder begins making the Þrst stroke of the plane.
4. Click the Mark IN button.
5. To advance two seconds, type +129 (+124 PAL) in the numeric
keypad and press Enter.
Since Avid Xpress counts the frame it is parked on, you type one
frame less than two seconds.
If you want to move back a certain number of frames, type a
minus sign (Ð) instead of a plus sign (+) in front of the number.
6. Mark that frame as the OUT point.
73
Subclipping
Now you will copy portions of one clip into shorter clips, called subclips. Subclipping is a great tool for organizing your footage into manageable units.
1. Double-click the tools clip in the Getting Ready to Edit bin.
2. Press the Home key to go to the start of the clip.
3. Scroll through the clip by pressing the Play button or dragging the
blue position indicator, and notice there are two separate actions
that can be copied into separate subclips.
4. Mark an IN point when the boatbuilder begins turning the auger
drill.
5. Mark an OUT point 14 seconds later by typing +1400 in the
numeric keypad and pressing Enter.
Actually, you have marked an OUT after 14 seconds and 1 frame,
but thatÕs okay because you need not be so precise here.
6. Press and hold the Option key, and drag the picture from the monitor to the Getting Ready to Edit bin.
As you begin dragging, the pointer changes to a hand attached to
a small box.
A new item called tools.Sub.01 appears in the Getting Ready to
Edit bin. The subclip has the name of the original clip, followed by
Sub.n, where n is the number of times the master clip has been
cataloged to that bin. The name is highlighted.
7. Type drilling and press Return (or Enter on the numeric keypad)
to name the subclip.
74
Clearing IN Points and OUT Points
1. With the tools clip in the Source pop-up Monitor, click the Clear
Both Marks button in the Tear-off palette to clear IN and OUT
points.
2. Mark an IN point in the clip when the boatbuilder begins hammering, after he takes a few practice swings.
3. Mark an OUT point at the end of the clip.
4. Press and hold the Option key and drag the clip from the Source
pop-up monitor to the Getting Ready to Edit bin.
The clip name is highlighted in the Getting Ready to Edit bin.
5. Type hammering and press Return (or Enter on the numeric
keypad).

CHAPTER 6
Editing a Rough Cut
Beginning to edit involves moving around in Avid Xpress. This is
described in the following sections:
¥Viewing Methods
¥Navigating in the Timeline
¥Displaying More or Less Detail
¥Using the Track Selector Panel
Tutorial: Rough Cut contains the following sections:
¥Making the First Edit
¥Splicing Video into the Sequence
77
Viewing Methods
You can work with clips and sequences in several different ways,
depending upon your needs and preferences. Each method has its
own uses and advantages, as follows.
¥Viewing in bins: Frame mode shows you pictorial images of the
clips in your bins; Text mode shows you the clips listed by name.
¥Viewing in the Source pop-up monitor: You can load clips and
sequences into the Source pop-up monitor to view and mark or
subcatalog shots for use in a sequence that you build in the Composer monitor.
¥Viewing in the Composer monitor: You can load a sequence into
the Composer monitor to view, mark, or modify an existing
sequence. You can Option-drag a clip or group of clips into the
Composer monitor to create a sequence.
¥Viewing in the Timeline: Use the Timeline to view individual
tracks for either a sequence or a source clip.
Navigating in the Timeline
The Timeline window provides various controls for quickly moving
through a sequence and adjusting your view of details displayed in
the tracks while editing. You can change Timeline views by using the
Timline fast menu.
Using the Position Indicator
The position indicator (the vertical blue line) in the Timeline marks
your place in the sequence. It also determines how some of your commands are interpreted. For example, when you perform an edit, the
78
system takes the location of the position indicator as the Mark IN in
the absence of established marks.
When you move the position indicator in the Timeline, the smaller
position indicator within the Composer monitorÕs position bar also
moves.
Using the Scroll Bar
The scroll bar functions like any standard Macintosh scroll bar. Click
the arrows or drag the scroll box to scroll left or right.
Scroll box
Scroll bar
Displaying More or Less Detail
The scale box in the scale bar stretches and contracts the Timeline area
centered around the blue position bar, allowing you either to zoom in,
focusing on a speciÞc area of your sequence, or to zoom out to see
your whole sequence. This is especially useful when you have a
lengthy sequence with many edits.
Scale bar
The Timeline always expands or contracts proportionally on both
sides of the position indicator.
¥To see more detail, click and drag the scale box to the right.
Scale box
79
As Timeline expands , a
shadow position indicator appears
As the Timeline expands, a second ÒshadowÓ position indicator
appears next to the blue position indicator showing the end of a
single frame, and the two continue to move apart as you expand
the Timeline.
The position indicator and its shadow mark the beginning and
end of each frame. The solid bar is the mark or edit point. You can
click on either the bar or the shadow to move exactly one frame
forward or backward.
¥To contract an expanded Timeline to see less detail but more of the
sequence, click and drag the scale box to the left.
Using the Track Selector Panel
The Track Selector panel provides numerous controls for working
effectively with multiple tracks. With this one resource you can select,
delete, monitor, enlarge, reduce, lock, patch, and move any video or
audio track.
The Track Selector panel also provides a quick display of track information. You can see which tracks (on the source or record side) are
available, active, patched, monitored, or locked. The conÞguration
shown below is just one example. The Track Selector panel may look
very different depending on the nature of the source material or the
work underway in the sequence.
80
Source track monitors
Source tracks
Track lock indicators
Record tracks
Record track monitors
Timecode track
The source side (left side) of the panel displays only those tracks available for the clip currently loaded and displayed in the Source pop-up
monitor. For instance, a clip that has audio digitized for track A1 only
does not display an A2 track in the Track Selector panel.
The record side of the panel displays only those tracks currently in use
for the sequence and displayed in the Composer monitor. However, if
you edit source material with a track selected that does not yet exist on
the record side (A3 or V2, in the previous example), by default the
track appears on the record side after the edit takes place.
81
Selecting T racks
You can select tracks on either the record side or the source side as
follows:
¥You can edit selected tracks on the source side directly into the
sequence, assuming you have selected parallel tracks on the
record side.
¥You cannot edit deselected tracks on the source side into the
sequence, regardless of record track selections.
¥You cannot edit deselected tracks on the record side, regardless of
source track selections.
There are three methods for selecting tracks:
¥Click any deactivated Track Selector button to select it. Click any
activated Track Selector button to deselect it.
¥Drag a lasso around multiple Track Selector buttons to select them
at once.
¥With the Timeline window active, choose Select All Tracks from
the Edit menu to select all tracks on the record and source side.
n
For example, you might select the source and record tracks for V1, A1,
and A2 to edit video and audio from the source clip into the sequence.
Select only V1 source and record tracks to edit the video without
sound. Or select only A1 and A2 to edit the sound without the video.
There are also keyboard equivalents for selecting tracks. Check your keyboard
or the Keyboard settings in the Project window Settings scroll list.
82
Monitoring T racks
You determine the monitoring of tracks by clicking the monitor column of either the source- or record-side tracks to activate or deactivate
the monitor icons.
Audio track
monitor
Monitoring Video
The video track monitor determines whether you see video during
playback. You can turn it off at any time to monitor only audio during
editing. When there are multiple video tracks, all tracks below the
monitored track are active during playback.
Video track monitors
Audio track
monitor
n
When you edit with multiple tracks, you can activate the monitor on a
lower track to monitor only the video on that track. This is especially
useful when you have multiple layers of video effects and need to see
one track without the additional layers.
If you reposition the video monitor, be sure to return it to the topmost track to
view, render, or record all the tracks together. Unmonitored tracks are not
included in playback.

clip into the Composer monitor.
If no points are selected,
the entire clip is edited
into the Timeline.
The clip is edited onto track A1 of the Timeline. The Þrst frame is the
IN point you marked in the clip; the last frame is the OUT point you
marked in the clip.
The audio track appears in the Timeline. The sequence also appears in
the Composer monitor.
Playing a Sequence
The Rough Cut bin contains your newly created sequence. By default,
Avid Xpress names it Untitled Sequence.01. LetÕs change this name.
1. Click the name Untitled Sequence.01 to select it; do not click the
sequence icon.
The name highlights in black and has a box around it.
2. Type Boat Shop Cut and press Return.

3. Click the position bar beneath the Composer monitor or anywhere
near the left side of the Timeline, then click the Play button to play
the audio.
The Audio Monitor
button appears when a
speaker is activated.
This audio track should run the length of the sequence, and its
duration should be approximately one minute.
Confirming the Duration
The next steps explain how to conÞrm the duration by displaying the
master timecode, which is the timecode of your sequence.
1. If Master timecode is not displayed, click and pull down the Timecode display from the gray area above the Composer monitor and
select Mas (Master) timecode.
The master timecode displays the location of the position indicator
in your sequence.
2. Move the position indicator in the Timeline or the Composer monitor to the last frame of the sequence.
The master timecode should read approximately 01:01:00:00.
Splicing Video into the Sequence
Play the whole clip
through once Þrst to get
a sense of the material.
Now weÕll start laying some video over the audio. For the opening
shot in the sequence, use the bridge clip.
1. From the Rough Cut bin, double-click the bridge clip to display it
in the Source pop-up monitor.
2. Mark an IN point midway through the clip, about 2 seconds after
the camera begins to pan left. Watch the timecode at the top of the
Source pop-up monitor to determine 2 seconds after the camera
pans left.
87
3. Mark an OUT point 3 seconds and 6 frames (5 frames PAL) later, at
approximately 01:13:43:23.

Splicing a Shot into the Middle of a Sequence
With nonlinear editing, you can splice a shot anywhere in your
sequence.
1. From the Rough Cut bin, open the kids rowing clip.
2. Mark IN and OUT points to mark 4 seconds of the camera panning from the girl to the boy.
LetÕs see what this shot looks like between the Þrst and second
shots.
3. Click in the middle of the ducks clip, between the position indicator and the bridge clip.
4. Press and hold k and click the mouse within the ducks clip in the
Timeline to place the position indicator on the Þrst frame of the
ducks clip.
5. Press the Splice-in (V) key on the keyboard.

Now, you will add two more shots to the sequence.
1. Open the kids in shadow clip.
2. Click the Clear Both Marks button on the Tear-off palette.
3. Mark an IN point in the Þrst half of the clip, one frame before the
second boat enters screen left.
4. Mark an OUT point 3 seconds and 17 frames later (PAL: 3 seconds
and 14 frames) by doing the following:
a. Choose I/O from the Tracking Information pop-up menu in
the gray area above the Source pop-up monitor.
The I/O option displays the duration from the IN to OUT
points. If you only mark the IN point, the I/O displays the
duration from the IN point to the position indicator.
b. Step forward until the I/O display reaches 3:17, and mark the
OUT point.
5. Move the position indicator to the Þrst black frame.
6. Press the V key on the keyboard to splice the clip into the Timeline
as the third shot.
7. Open the rowing forward clip and mark an IN point a little less
than halfway through the clip, when the dory is evenly centered
between the right and left edges of the frame.
8. Mark an OUT point 5 seconds later.
9. Splice the clip into the Timeline as the fourth shot.
10. Choose Save All Bins from the File menu.

ReÞning the Edit
ReÞning edits tightens and improves the relationship between pictures and sound. This is described in the following sections:
¥Using Segment Mode
¥Basic Trim Procedures

¥Trimming
¥Working with Audio
93
Using Segment Mode
Segment mode provides editing controls for moving, deleting, marking, and editing entire segments in the Timeline. A segment is a portion
of the sequence that includes two or more transitions. There are two
modes for editing segments or adding shots: Extract/Splice-in, indicated by a yellow arrow, and Lift/Overwrite, indicated by a red arrow.
Unlike traditional editing, Segment mode allows you to instantly
reposition entire segments using visual controls as though you were
physically ÒdraggingÓ portions of your sequence around on a tape.
You can move shots separately or together, on one track or across
tracks.
Editing in Segment Mode
Observe the following guidelines when editing in Segment mode:
¥Transition effects on either side of a moved selection are deleted.
Transition effects inside the selection are preserved.
¥You can track the audio while moving segments by pressing the
Caps Lock key to enable audio scrub.
¥When you are Þnished, Segment mode continues to affect your
editing unless you click the active Segment Mode button to
deactivate it.
Distinguishing T wo Types of Buttons
In Chapter 6, you used the Splice-in button. The Splice-in button and
the Overwrite button (see ÒOverwriting Shots into a SequenceÓ on
page 101) take clips from the Source pop-up monitor and put them
into the Timeline. The Segment Mode buttons, Extract/Splice-in and
Lift/Overwrite, move segments around within the Timeline. The
names are similar but you use them for different purposes.
94
Basic T rim Procedures
For illustrations of the
various types of trim
edits you can perform
in Trim mode, see the
Avid Xpress Quick
Reference.
You can enter Trim mode in several different ways, depending on the
type of trim you expect to perform. Once in Trim mode you can:
¥Select additional tracks
¥Toggle between trim sides
¥Perform and play back the trim
Entering T rim Mode
There are three methods for entering Trim mode:
¥Clicking the Trim Mode button in the Tear-off palette. By default
the system enters Trim mode and selects the tracks nearest the
position indicator for dual-roller trimming. This method is useful
for selecting straight-cut transitions on one track or across video
and audio tracks.
Transition selected
for trimming
When you deselect one or more tracks in the Track Selector panel,
by default only the transitions in the highlighted tracks are
selected for trimming. If the transitions are not straight cuts (overlap cuts or L-edits), the system highlights the topmost track nearest the position indicator.
95
¥Lassoing the transitions in the Timeline. Draw the lasso by click-
ing at a point above the top track in the Timeline and dragging to
surround the transitions. This method is useful when you need to
select multiple transitions staggered across parallel tracks (overlap
cuts) for simultaneous trimming.
Lasso drawn across three tracks
Transitions are selected for dual-roller trim
You can drag from right to left, or left to right, and you can lasso
single transitions across several contiguous tracks. However,
avoid lassoing more than one transition on a single track, because
this activates Segment mode.
n
To select transitions located below several track layers, draw a lasso within
the Timeline by pressing the Control key while you drag.
¥Pressing the Go to Previous Edit or Go to Next Edit keys
(A or S). By default the system selects the nearest transition in
either direction of the selected track for dual-roller trimming.
If the transition is a straight cut, the system selects all edited
tracks. If the transition is an overlap edit with staggered transition
points, the system selects the topmost track.
96
Exiting T rim Mode
You can exit Trim mode at any time in one of several ways:
¥Click the Effect Mode button.
¥Press the Escape key on the keyboard.
esc
¥Click a speciÞc location in the Timecode (TC1) track at the bottom
of the Timeline to exit Trim mode. The position indicator moves
to that location.
Click in the TC track at a
selected location
Selecting Between Trim Sides
A-side B-side
A and B
To select sides of a transition to trim, click the outgoing (A-side) or
incoming (B-side) monitor to deÞne which side of the transition to
trim. Notice that the pointer changes to a single-roller A-side, singleroller B-side, or double-roller icon depending on position.
The system exits Trim mode and
relocates the position indicator
A-sideB-side
Highlight indicates
active sides
The selected parts of the transition are highlighted, and the corresponding rollers appear in the Timeline. Also, one or both of the frame
counter indicators below the monitors are highlighted to reßect the
active trim sides: A-side, B-side, or both. The number indicates how
many frames have been added or subtracted (-) from the transition.
97
Performing a Basic Trim
With your transitions and trim sides selected, you can perform a basic
trim using one of the following procedures:
¥Use the Trim buttons to trim forward or backward by one- or ten-
frame increments.
1 frame
10 frames
¥Use the numeric keypad at the right side of the keyboard, as fol-
lows:
-To move the transition a speciÞc number of frames, type a
plus sign (+) or minus sign (Ð) and the number of frames (from
1 to 99) you want to move forward or backward. Then press
Enter. If the number of frames is larger than 99, type an F after
the number to indicate frame count. For example, to enter 200
frames, type 200F and press Enter.
-To move the transition to an exact timecode, type a timecode
number larger than 99, including frames. For example, type
102 to enter 1 second and 2 frames.
¥Use controls in the Timeline by clicking a roller at the selected
transition and dragging forward or backward in the sequence.
Click and drag a transition in the Timeline
¥For greater control:
-Press the Option key as you drag to move one frame at a time.
-Press the Command key to snap to other transition points.
98
As you trim, all selected transitions in the Timeline move in unison.
The Frame counter displays the frame count backward or forward for
one or both trim sides, and the monitors display the new incoming or
outgoing frames.
n
Audio Editing
To trim successfully, the clips must have available frames on either side of the
IN and OUT points. These frames must be more or the same in number as
frames you are going to trim.
The Avid Xpress system provides audio scrub features and waveform
plots speciÞcally designed for frame-accurate cueing, marking, and
editing of audio. You can use these features any time during editing or
while making adjustments with the audio tools.
You can use the Audio Mix Tool to adjust volume (level) and balance
(pan).

Overwriting Shots into a Sequence
In addition to splicing, you can overwrite shots into a sequence. An
overwrite edit replaces a section of a sequence with other source footage. An overwrite edit does not affect the length of the sequence.
The rowing forward shot is too long. In this section you will edit the
next shot into the sequence before the end of the rowing forward clip.
1. Make sure the Composer monitor is active.
2. Place the position indicator in the Timeline on the Þrst frame of
rowing forward.
3. Advance 3 seconds by entering +229 (+224 PAL) in the numeric
keypad, then pressing Enter.
4. Mark an IN point.
5. Open the dories passing clip.
6. Mark an IN point in the Þrst half of the clip, 18 frames (15 frames
PAL) after the tips of the two boats seem to touch in the middle of
the screen.
7. Mark an OUT point a few frames less than 7 seconds later, when
the girlÕs oars are both out of the water, and her left oar just catches
the light.
