You can't really resync FEL though.

Yeah, but seems I am not able to fix this one. I have MadVR installed, Lav filters and all.

This is not a fun error to deal with, as I had it before and took me a long time to resolve, lots of uninstalling/re-installing and troubleshooting. From what I recall, the key was to ensure I had 32-bit (x86) version of LAVFilters installed and registered, as well as AviSynth+ (may or may not be related to your specific IMeasureHDR error msg), as madMeasureHDR.exe is actually quite an old executable that has not been updated by madshi for a while and it does not play nice with 64-bit anything. Make sure not to use any weird paths and consider making a new Windows user account to confirm it's not an issue with your user profile/registry. Good luck!

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?

I'm just curious, why do you want to convert to lower bit-rate?

And second, I like to save place. I am happy with some quality downgrade when I can reduce video size. I can not afford hundred TBs of storage.

This is precisely what "optimized versions" feature in PLEX is for, have you considered trying that? It transcodes and saves a smaller version of any movie in your library, so that it is compatible with all devices/situations, and doesn't have to do real-time transcoding. Just a thought.

then idk, show me the log with ''echo'' set to ''on'' maybe.
you can also try it manually:

D:\DoVi_Scripts\tools\madvr\madMeasureHDR.exe "D:\Interstellar.2014.iMAX.HDRg 2.9 itunes (4000nits).mkv"
Measuring video file "D:\Interstellar.2014.iMAX.HDRg 2.9 itunes (4000nits).mkv" using D3D11 (native)...
