Hello, I stumbled upon issue, maybe someone here might be able to help me.
I want to convert 4K DV+HDR10 MKV into lower bitrate MP4 to play DV on my LG Plex.
Normally, when I only want to change the container from MKV to MP4 I just use
Code: Select all
ffmpeg.exe -i "source.mkv" -map 0 -c copy -c:s mov_text -strict unofficial "output.mp4"
and all is nice and dandy. It triggers DV on my LG, but preservers the HDR10 metadata also, so all is OKay.
When I want to convert video stream I use:
Code: Select all
ffmpeg.exe -i "source.mkv" -map 0 -c copy -c:0 hevc_nvenc -cq 32 -preset p5 -c:s mov_text -strict unofficial "output.mp4"
and it also copy all DV/HDR metadata, it even triggers Dolby Vision playback on TV (DV logo appears in the top right) but brightness is like in SD material. MediaInfoGUI claims all is okay. I lose HDR10+ but I do not care for that.
First is original MKV file:
converted MP4:
Any ideas whit it triggers DV but plays in low brightness?
