We are almost there. I have two notes: > - the output file has different permissions (this way Plex could not read > it just after I modified perissions like other files have) > - my tv only plays it as HDR10+ instead of Dolby Vision, this is the main > point of converting. mk4s are played in HDR10+, if I change container it > played as Dolby Vision (with my win software, XMediaRecode). >
Hi, I'm going to answer in general, with several pointers: - First, please avoid top-posting on this mailing-list - see https://ffmpeg.org/mailing-list-faq.html#What-is-top_002dposting_003f-1 - Second regarding file permissions, again, this is not ffmpeg related. Please google "changing unix file permissions" and/or "setting default unix permissions for new files" - Finally, regarding the ffmpeg part, your command line specifically includes "-c copy" which is means "don't do any reencoding", so the output obviously uses the same codecs as the source. Only the "enveloppe" (wrapper) changes from mkv to mp4, but the actual streams it contains are untouched. To reencode video probably requires a combination of "-c:a copy" (meaning: avoid any *audio* reencoding) and "-c:v xxxx" (meaning reencode video with codec xxxx). Now admittedly I don't know which exact expression is required for HDR10+ encoding, or even if it is supported at all. Unfortunately, a quick Google search for this question leads to https://superuser.com/questions/1651568/how-to-convert-dolby-vision-hdr-to-hdr10 which starts with "Update January 2025: This remains an open question. Current answers below do not solve the issue." So I'll let more knowledgeable people answer on this specific point.
