STEPS TO REPRODUCE
1. add video file
2. Add defish to the effect for entire track or to video clip. I set defish to 780 under amount.
3. Attempt to render video. I am using 4k video.

OBSERVED RESULT
Crash upon render

EXPECTED RESULT
Actually render the video

ADDITIONAL INFORMATION

Comment 1 erjiang 2022-12-07 04:23:07 UTC

It looks like you're using the Kdenlive packages provided by your distro. Distro-provided packages are known to often have incompatibilities between Kdenlive and its dependencies. Try using the AppImage provided on kdenlive.org to see if that resolves your problem.

If that does not work, try one of the following:
* Turn off hardware/GPU acceleration when rendering
* Turn off parallel processing when rendering

and report back on whether either of those two options resolves the crashing.

Please try with version 22.12.0. Make sure parallel processing is switched off in render -> more options.

Comment 3 Charles 2022-12-18 14:10:38 UTC

Turning off parallel processing fixed it. I always had that on without issues previously though. So the bug is still there. It may be something in my version of Manjaro/system kernel or kdenlive, I'm not sure. At least I can get the work I need done though thanks. Lots going on in software these days and I'm no genius in the world of PC.

Comment 4 emohr 2022-12-18 15:51:29 UTC

Thanks for confirming. Yes, parallel processing is still an issue.
