SUMMARY

When rendering a video, Kdenlive provides me a message notifying me that the renderer crashed and that content of the short may be corrupted after the last frame. The video has not had any issues after reproducing this across 2 different videos 5 times between the both of them.

STEPS TO REPRODUCE
1. Set up a project with the included custom video setting of "Vertical HD 60 FPS" and your project folder as a custom folder.
2. Add a clip to your project timeline with title clips layered on top of the main clip video.
3. Add the "Transform" and "Crop, Scale, and Tilt" filters to your main clip video.
4. Render your clip and have it set to export your rendered file to a different folder than your project folder. 

OBSERVED RESULT

Crash error from the renderer, but the resulting video is without noticeable issues.

EXPECTED RESULT

No renderer crash.

To check if this is a packaging issue please try with the official flatpak or AppImage: https://kdenlive.org/en/download/

I have installed the official flatpak and rendered 2 different projects to test for this issue and it has not happened. I'm still glad I caught the issue in the RPM though.

Thank you for testing. Glad to hear it works. 
Then it’s definitely a packaging issue, most probably by Fedora. If you like you can report that upstream. 

I close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
