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.
