Hello, -Forgive meI will do my best. This complete system is strange for me and I am stil learning. -Permissions: I could not deicede if ffmpeg was doing it or it was mysystem. I just faced this was the permission problem, other way I did not. I will check it, but this was the smallest problem. -exactly this is the goal. Just to change container, without reencoding. My harware is not too heavy duty, and if it can work withpout encoding, I would choose that. The working solution is given by Ferdi just after your letter, adding "-strict unofficial" solved the problem. - So as I (somehow) have some other versions that the latest installed I must call the latest with specifying the complete path - "-c copy" for just changing container - "-c:s mov_text" for transforming the subs the format valid for mp4 - "-strict unofficial" to keep the DolbyVision part of the mkv /volume1/@appstore/ffmpeg7/bin/ffmpeg -i input.mkv -map 0 -c copy -c:s mov_text -strict unofficial output.mp4 Thank you for helping out.
