I have tryed to export the project as mp4 file and also as avi file. Current resolution is 800 * 600 (dividable by 2).
Exporting to animated gif files is working.

If I remove the sound level (which contains an mp3 file), everything is working fine.

Same result if I convert the mp3 file to wav.

Expected result

An MP4 or AVI file should be created

Actual result

FFMpeg crashes so a crash dialog appears.

Steps to reproduce

1. Create a new project
2. Import a wav or mp3 file in a new sound layer
3. Export the project as a MP4 or AVI file (Menu "File"-> "Export" -> "Movie")

Video or Image Reference

No response
