Summary: Kdenlive freezes computer when exporting MP4
Product: kdenlive
Version: 20.08.2
Platform: Ubuntu Packages
OS: Linux

SUMMARY
Kdenlive crashes when exporting a MP4 video. Tried exporting WEBM and it worked
fine.
The file has a few mp4 videos that are joined in the sequence. When I select
the rendering type and it starts rendering, it keeps loading until about 70%,
then the whole computer freezes.
The first time it happened I was using the computer with other software (like
chrome). The other times the software was running withou my interaction. I
tried:
- Exporting MP4, crashed
- Exporting WEBM, succesful
- Exporting MP4 via scrip, crashed
- Exporting WEBM then MP4 via scrip, succesfull then, on MP4, crashed
Project settings: Vertical HD 60fps
Export settings: MP4 - the dominating format (h264/aac)
STEPS TO REPRODUCE
1. Load a few mp4 files into the project and organize them in the timeline
2. Hit export with the aforementioned configuration
3. Wait until the computer freezes
OBSERVED RESULT
Computer entirely freezes without any error messages, can't see any log, have
to reset.
EXPECTED RESULT
Video is exported succesfully
