Apple Final Cut Pro 6 - Manual (Page 1511)

28 Part I Media and Project Management
If you upgrade a project or sequence created in Final Cut Pro 1.2.1 and the codec used
for the sequence is not found by the system, the codec in the Sequence Settings is
listed as “Unknown” and “Always Render in RGB” is selected in the Video Processing tab.
If you want to render the sequence in Y´C
B
C
R
(YUV) color space, you need to change
this manually.
To enable YUV processing in a sequence with an unknown codec:
1 Choose Sequence > Settings, then click the General tab.
2 In the QuickTime Video Settings section, choose DV-NTSC or DV-PAL (whichever you
are using) from the compressor pop-up menu.
3 Click the Video Processing tab, then select the YUV rendering option you want to use
for your sequence.
Unless you are doing high-end video processing, you will probably want to select
Render in 8-bit YUV.
For more information about rendering in RGB and Y´C

color spaces, see Volume III,
Chapter 29, “Rendering and Video Processing Settings.”
Note: These options are available for codecs that support Y´C

R
color space.
Keeping a Copy of Your Project in an Older Format
When you open an older project, Final Cut Pro updates the format to the current
version. However, the updated project only exists within the Final Cut Pro application,
not on disk, until you save it. This means you can save a copy of the project in the
current version and still keep the older one on disk.
To keep a backup of your project in its original format:
1 In the Finder, choose a project from an earlier version of Final Cut Pro, then choose
File > Duplicate (or press Command-D).
If you want, you can rename both the original or the duplicated project to indicate its
version number. For example, you can add “_v5” to the end of a project file associated
with Final Cut Pro 5.
2 Open the duplicated project in Final Cut Pro, then choose File > Save.
You can open and use projects created with earlier versions of Final Cut Pro and
Final Cut Express, but you need to specify how you want Final Cut Pro to handle the
color space in these files.
