Working with Mixed-Format
Sequences
Final Cut Express allows you to mix formats in the
Timeline so you can combine and play back footage with
different codecs, frame rates, and image dimensions in
a single sequence.

About Mixed-Format Sequences
A mixed-format sequence is a sequence containing clips whose media files don’t
match the sequence format. Final Cut Express can play sequence clips in real time even
when the clips’ settings don’t match those of the sequence. Any number of formats can
be combined together in a single sequence.
You can use mixed-format sequences to:
 Combine standard definition (SD) and high definition (HD) footage in one sequence
 Mix PAL and NTSC footage in a single sequence
 Work with offline-quality and full-resolution footage together
 Mix video with different aspect ratios, frame rates, or codecs in a single sequence
