Converting profile 7 to profile 8

[AvihaiV]

Hi,

I have an MKV file with HDR and DV.
This is the DV info:
DOVI configuration record: version: 1.0, profile: 7, level: 6, rpu flag: 1, el flag: 1, bl flag: 1, compatibility id: 6

I am running the following comand to extract the audio and video:
ffmpeg -i input.mkv -map 0:v:0 -c copy video.hevc -map 0:a:0 -c copy audio.eac3

Then I am running the following command to convert the hevc file to profile 8:
dovi_tool -m 2 convert video.hevc --output video_profile8.hevc

Then adding all file to mp4 file:
MP4Box -add video_profile8.hevc -add audio.eac3 output_profile8.mp4

When checking the output file DV configuration it stays the same:
DOVI configuration record: version: 1.0, profile: 7, level: 6, rpu flag: 1, el flag: 1, bl flag: 1, compatibility id: 6

What am I missing here?

Thanks!

You didn't add --discard to the convert command so the EL is still present and MP4Box sees it as profile 7.

Thank you!
So the correct command is:
dovi_tool -m 2 convert video.hevc --output video_profile8.hevc --discard

I have another question, please.
When checking the original mkv file, I see all the metadata, but in the final mp4 I don't see anything, such as chapters and songs.

Is it possible that I am missing something along the way?

Thanks!

You're simply muxing the video and audio.
You need to find out how to retain the rest.

Ok thanks!
