SUMMARY
When trying to motion-track a sequence, clicking "analyze to apply effect"
freezes the program and it crashes shortly after.
My current work-around is to render the section I need into an mp4 and replace
the sequence section with that and then apply tracking.
STEPS TO REPRODUCE
(I tested in brand new project)
1. Add 2 video clips on 2 video tracks
2. Select these 2 clips, right click and click "create sequence"
3. Click the newly created sequence clip and add a motion tracking effect (I
tested with algorithm MOSSE and every 1 frame)
OBSERVED RESULT
Kdenlive freezes and crashes in 5-10 seconds.
EXPECTED RESULT
Extracting keyframes with motion tracking should work with sequences as if it
was analyzing a normal mp4 clip.
