Media Management and Project Interchange
Working with mixed formats in a sequence can present unique media management
challenges. The following section describes limitations in the following areas when
working with mixed-format sequences:
 Using the Media Manager
 Exporting EDLs
 Using Cinema Tools
Using the Media Manager with Mixed-Format Sequences
When you process media associated with a mixed-format sequence, keep in mind that
Final Cut Pro bases most of its functions on the frame rate of the sequence, not the
media file. If you are simply using the Media Manager to copy or move a sequence and
its associated media, your media is merely duplicated. However, if you choose options
such as Delete Unused Media or Recompress, you should check your results to make
sure nonmatching image dimensions, frame rates, and codecs did not cause
unexpected results. Processing mixed-format sequence clips with speed changes
through the Media Manager may also cause unexpected results.
Exporting an EDL from a Mixed-Format Sequence
All clips in an exported EDL are assumed to have the same frame rate as the sequence.
When you export an EDL from a mixed-format sequence, source timecode In and Out
points are shown at the sequence frame rate, not the source timecode rate. As a result,
you may not be able to use an EDL exported from a mixed-format sequence for
recapturing footage.
Working with Cinema Tools and Mixed-Format Sequences
Mixed-format sequences are not recommended for use with Cinema Tools. Mixed-format
sequence playback does not perform 3:2 pull-down removal, deinterlacing, or accurate
timecode or keycode tracking of your clips. If you are editing film-based media in
Final Cut Pro, you should use any of the suggested workflows described in the
Cinema Tools User Manual.
