Apple Final Cut Pro 7 - Manual (Page 1507)

Improved Color Accuracy When Rendering High Definition Sequences
If you open an old project containing any rendered high definition sequences, or if you
have any SD sequences containing HD source media, a dialog asks if you want to open
the project and permanently delete the existing render files. If you want to preserve the
existing render files, do not open the project in Final Cut Pro. Deleting the render files
cannot be undone.
Note: If your project only refers to SD footage (ITU-R BT. 601), this dialog does not appear.
Updating Projects from Final Cut Pro 3.0 or Earlier
Clips in projects created with Final Cut Pro 4 and later have master-affiliate clip relationships
that did not exist in earlier versions of Final Cut Pro. When an older project is imported
into Final Cut Pro, this relationship is not automatically created, but you can manually
update your project so that every sequence clip becomes affiliated with an appropriate
master clip in the Browser. For more information about creating master clips, see
“About
Using Master and Affiliate Clips.”
To create master-affiliate relationships for clips in an older project
µ
After you open and update the project, choose Tools > Create Master Clips.
Master clips are created for every clip in every sequence, and placed in a bin called Master
Clips for [Project Name]. When multiple clips refer to the same media file, only one master
clip is created for those clips.
Updating Projects from Final Cut Pro 1.2.1
In Final Cut Pro 1.2.1 and earlier, sequences using the Apple DV-NTSC and DV-PAL codecs

video to RGB video whenever rendering was required. The conversion
sometimes resulted in subtle but noticeable shifts in color or intensity. Starting with
version 1.2.5, Final Cut Pro handled color space differently; however, old projects may
still have links to older render files that exhibit the color and intensity shifts.
If you open an old project containing any rendered DV-NTSC or PAL sequences, a dialog
asks if you want to open the project and permanently delete the existing render files:
• Update sequences for improved color fidelity: This sets the maximum white value to

Editor windows. All future rendering in the sequence is done in Y

Note: If you select this option, the “Always Render in RGB” option in the Sequence
Settings or Sequence Preset Editor window is not selected. For more information, see
