How can I rotate a video?

[propagare]

I have some videos (in Synology Photos) that are misaligned. Thank God I have ConvertX in Docker installed.

Is there a way to rotate them with ConvertX?

Maybe I can set the environment variable FFMPEG_ARGS to FFmpeg flags such as -vf transpose=1 (90° clockwise), -vf transpose=2 (180°), -vf transpose=3 (90° counterclockwise), or -vf hflip,vflip (mirroring?

for more advanced video editing I think the easiest is to download them and do it locally

Yes, but then I have to do it myself for the whole family! So it would be nice if there was a solution in ConvertX that would allow them to do it themselves.

Perhaps there is a way to pass individual parameters such as those above to FFMPEG in a field?

That is something that could be added, create a feature request in issues if you want :)

Done! :)
