Bug
1

What is your operating system?
Windows 10

What is your Shotcut version (see Help > About Shotcut)?
24.06.26

Can you repeat the problem? If so, what are the steps?

  1. Load Video file(430 x 240 is enough, 29.97 fps)
  2. warp_speed 10
  3. Add choppy, set to 10 frames - playback works
  4. Set to 2 frames - playback works, but it doesn’t show 2 frames chopped but faster
  5. Stop
  6. Play again on 2 frames choppy segment → crash

I did not reproduce it using a 1080p60 MP4 on the Timeline. Do you if you repeat your steps? Try it again. I am not sure if the Properties > Speed change is a required step, but you can check that. And if it is, a workaround might be to export with the speed change and no Choppy filter to an intermediate file and then use Choppy on that intermediate.
