• Remove existing render files: This deletes all render files on the scratch disk for the
sequences in this project. If you keep existing render files, the rendered media may
have color or intensity shifts. You should keep existing render files if the quality
difference is not a problem for your projects or if you need to get a project done fast
and don’t want to rerender files. If you keep existing render files and want
consistent-looking media, you’ll have to rerender the files because sequences in
previously rendered media may have color or intensity shifts.
Note: You cannot restore deleted render files with the Undo command.
Choosing these options will not rerender any material immediately. You need to open
any affected sequences and render them manually.
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

your sequence.
