Issues When Working with Mixed Frame Rates
When you add a clip to a sequence and the frame rates don’t match, Final Cut Pro
places the clip as accurately as possible in the Timeline. However, because of the
differences between some frame rates, there may be a one-frame shift on either the
In or Out point of the clip. This is normal behavior caused by the limitations of
mixed-frame-rate editing. After you add a nonmatching clip to a sequence, always
check to make sure your clip In and Out points appear the way you want, and adjust
them if necessary.
Copying and pasting clips from one sequence to another can also create
mixed-frame-rate scenarios. Frame rate errors can accrue if you repeatedly copy
sequence clips to new sequences with nonmatching frame rates. When possible, it’s
always better to edit with master clips from the Browser instead of dragging clips
Motion has a different frame repeating and frame skipping pattern than Final Cut Pro,
so you may see different frames repeated than expected when including Motion
projects in a Final Cut Pro sequence.
