Sorry for not providing you with the information following the correct procedues (I'm no dev).
Here's my crash info - using Kdenlive: 21.12.0 in Windows 11:

Kdenlive is a really nice tool!

Thank you for reporting. It seems it crashed when you rendering. Please upload here the Kdenlive project file so we can have a look. What type of video do you use (out of a GoPro camera)?

File that crashes, including subtitle.

Comment 3 ad 2021-12-19 14:37:16 UTC

Thanks for replying!
Uploaded the file (with subtitle-file).

Comment 4 emohr 2021-12-19 18:56:18 UTC

The wipe effect on the end is not needed or should be between V1 and V2. Goto Timeline -> click "Disable Timeline Effects" -> render again to see if it still crash without effects.

Comment 5 emohr 2021-12-19 18:57:35 UTC

I could render the project with clip placeholders.

Hi emohr, here the newly rendered file (including log) - after applying the changes you suggested (no effects at all in this file).
Thanks again.

Comment 7 farid 2022-08-26 19:04:49 UTC

So this is fixed? We can close it?

Comment 8 ad 2022-08-27 05:57:12 UTC

Sorry Farid, for not monitoring the thread.
For some time I'm not working with videos now, so this made me negligent.
Yes, you can close the thread.
If in the future I pick video editing up again, I'll see what happens.

Thanks by the way for Kdenlive!
Greetings,
