Installing Final Cut Pro 1.2.5

Before you install Final Cut Pro, make sure you

m turn off any virus protection and security software installed on your computer
m install the version of QuickTime that is on the Final Cut Pro CD

If desired, unlock QuickTime Pro using the instructions provided in the update sheet that
came in your Final Cut Pro box.

The installation procedure has changed slightly from previous versions. To install Final Cut Pro,
follow these steps:

Insert the Final Cut Pro CD into your CD drive and double-click the CD’s icon to open it.

2 Double-click the Install Final Cut Pro icon and click Continue.

3 Read the Software License Agreement, then click Accept.

4 Read the Final Cut Pro 1.2.5 Read Me for important information, then click Continue.

5 If desired, select a location and folder where you want to install the software, then click Install.

6 Select your video capture method (DV or None/Don’t know) and the video format (NTSC or

PAL), then click Continue.

For specific information on various defaults that are set when you make your selections, see
“Defaults Set Based Upon Installation Options” on page 4.

7 When a message says installation was successful, click Restart.

Naming and Sorting Clips in the Browser

The Browser sorts clips in numerical order on computers using Western language script
systems (English, French, and German). Keep this in mind when you are naming files, so they
sort in the desired order. In earlier versions of Final Cut Pro, you needed to insert a leading
zero in a clip’s name in order to sort in numerical order.

If items in the Browser consist only of Roman low-ASCII characters (values of 32–127),
followed by a number, then these items are sorted in numerical order, taking the value of the
ending number into account. For all other text, the previous alphabetic-only sorting is used.
This means that double-byte fonts (Kanji) still need a leading zero in a clip’s name in order to
sort in numerical order.

m Current way of sorting: Clip 1, Clip 5, Clip 30, Clip 100
m Previous way of sorting: Clip 1, Clip 100, Clip 30, Clip 5

Specifying the Maximum File Size for Capturing and Exporting

A new option in the Scratch Disk preferences allows you to set the maximum file size for a
single capture or export session. If the maximum file size is reached during a capture or export
session, Final Cut Pro automatically creates another file and links these files together.

Note: For HFS volumes, additional files will automatically be created when the file size
reaches 2000 MB.

To set the maximum capture/export file size, follow these steps:

1 Choose Preferences from the File menu, then click the Scratch Disks tab.

2 Make sure there’s an X in the checkbox next to “Maximum size for capture/export file

segments,” then enter the desired file size.

To specify a maximum
file size, make sure there’s
an X in this checkbox.

Enter the desired
file size here.

Rendering in YCrCb (YUV) Color Space

Final Cut Pro 1.2.5 supports image processing, or rendering, in the YCrCb color space
(sometimes referred to as YUV ), in addition to the RGB color space. There are also various
options for white level processing. Both of these let Final Cut Pro preserve the maximum color
fidelity for processed images.

Converting Between YCrCb and RGB Color Spaces

Many digital video formats store data in a color space known as YCrCb. Three components are
stored for each pixel—one for luminance ( Y) and two for color information (Cr and Cb).
Typically, computers store data in RGB color space, which also has three components for each
pixel—one each for the red, green, and blue parts of the image.

Information can be converted from one color space to the other. However, since the color
spaces are not identical, there are many colors in each space which cannot be described in the
other. These colors get “clipped” to the nearest value during conversion. This can cause very
saturated colors to become less intense and is referred to as “chroma clamping.”

Another problem between the two color spaces occurs because of the levels at which some DV
cameras produce Y values. In YCrCb color space, values are typically defined from 16–235,
while in RGB they range from 0–255. Some cameras produce Y values above the 235 range,
even as high as 254 (also known as super-white). When these values are converted to RGB,
they can’t go higher than 255. When the RGB value is converted back to YCrCb, it will have a
maximum value of 235, less than the original value, causing viewing differences in the media.
This is known as “luma clamping.”

Final Cut Pro 1.2.5 eliminates these two problems by processing in YCrCb when appropriate
and eliminating the conversion to and from RGB color space.

Working With the YCrCb Color Space

You can specify settings to take advantage of the new YCrCb color space rendering. These
options are in the Preset Editor and Sequence Settings windows.

Note: To use projects created in earlier versions of Final Cut Pro, you need to update them for
the new color space. For more information, see “Updating Projects Created With an Earlier
Version of Final Cut Pro” on page 7.

To select settings, follow these steps:

1 Do one of the following:

m Choose Settings from the Sequence menu.
m Choose Preferences from the Edit menu and click the Sequence Presets tab. Select a preset,

then click Edit.

2 Click the Video Processing tab.
