Description ryand45647457434 2025-11-27 15:30:56 UTC 
SUMMARY
Rendering crashes without any information when a video with rotation information is present. I don't know if this was already fixed in newer versions since I've reported a now fixed bug where rendering anything with rotation information crashes kdenlive entirely (newest kdenlive nightly build has some critical glitch that I will report in a separate bug).

STEPS TO REPRODUCE
1. Render any project or sequence that has a video with rotation information.

OBSERVED RESULT
Mouse cursor turns into "working in background", and rendering crashes without any information about it.

Started render process: C:/Program Files/kdenlive/bin/melt.exe -loglevel error -progress2 C:/Users/[username]/AppData/Local/Temp/kdenlive-[tempprojectexport].mlt
29	3	1
30	25	11
Rendering of [project].mkv aborted, resulting video will probably be corrupted.
Frame: 25

EXPECTED RESULT
Rendering should have succeeded.
