Dolby Vision now possible through MP4 Mux.

No because when you bake FEL, it usually increases the brightness over 1000nits and if you keep the original MDL/maxcll, it will be clipped in HDR10 because the TV will use the 1000nits tone mapping curve with a higher roll-off point.

All of this depends on how the TV handles static tone mapping in HDR10 though but generally speaking, it's better to use the same MDL as DV.

Thanks for insight

If one watches the baked FEL encode on a non DV capable TV. Will using the maxcll and maxfall from the RPU be still correct?

[RESET_9999]

yes that's what I just said.
The HDR10 metadata doesn't matter for DV TV and FYI, Samsung TVs ignore maxcll, they only use MDL

You got that picture of the greyscale 10%?

sorry, the 5-10% grayscales are too dim. My camera cannot capture it... I have to raise ISO, which introduces noise that masks the issue.


EDIT: actually what I'm seeing is exactly like in this video:

For what it's worth I've been watching movies in DV on my 83" G5 for a few weeks now and have not been able to see the dithering effect in any content in the darkest of scenes from my seating distance of 10' away. And believe me I looked.

FYI, the dithering lines are totally visible in real content (dark scenes) and they look horrible at 8-10ft. Check this out, when she closes the door and turns around.

Not visible on the C2 on this same scene but the C2 also has those moving/falling lines on the 5-10% grayscale.

Is it normal for the DV P5 version of a given stream to be around 30% larger than the equivalent HDR10 version?
For example:
Andor.S02E04.2160p.DSNP.WEB-DL.DDPA5.1.DV.HEVC-PlayWEB.mkv: 6431381983
Andor.S02E04.2160p.DSNP.WEB-DL.DDPA5.1.HDR.HEVC-PlayWEB.mkv: 4305241410

I also notice that the hybrid P8 files people are posting are around the same size as the HDR10 versions. Is something being lost from the P5 files during that conversion?

[RESET_9999]

DV was just encoded at a higher bitrate. 15mb/s vs 11mb/s
Get the higher bitrate version, P5 basically like FEL DV anyway. So yeah, there is a loss in the P5 to P8 conversion.

how is the DV performance of jellyfin? is it incorrectly?

As long as you're not transcoding it's the same as playing direct from network

Yes DV5 versions of titles are always/almost always encoded at higher bitrates than HDR10 versions of some files from what I've seen - I imagine it's 'spec' or 'guidelines' by Dolby for DV certification/redistribution 'can't be below/must be at certain bitrate/threshold' in order to show 'how DV is the best' - Lord knows the streamers would love to reduce bitrate/transmission costs/storage/etc as much as they can get away with.

i want to know if the profile playback is correctly of the DV metadata?

That's going to depend on the device you're playing it on. On an Ugoos AM6B Plus running CPM build of CoreELEC with the Jellyfin Kodi addin, DV playback is correct.
