"rotation" problem on export

[carnussien]

Hello,
On preview i can apply rotation on the video and see the rotated video.
BUT "export" does not keep the rotation.
The video keeps its initial orientation.
Can you help?
Thanks
PS: I forgot to add that i am using a lossless-cut appimage for linux (ubuntu)..

if you can provide a short sample file then I can look into it

Thanks for your sample. I just realized that MKV doesn't support lossless rotation (the rotate metadata). Correct me if I'm wrong!
If you try with an MP4 file it will work.

Exporting to MP4 instead of MKV does the trick, if you don't care changing the format.

@mifi please evaluate to make LC alerting the user in case of an attempt to rotate a MKV. Maybe a suggestion to change the output format to MP4 (or something) could help even more to improve the UX.
