Re: Dolby Vision now possible through MP4 Mux.

Still, I don't understand how it is possible to change MDL or MaxCLL/FALL without re-encoding the video, but if it doesn't practically impact playback at all i think I'll get over this thought. It's just SEI in the bitstream. There's been some other people asking me for a tool to do it, and I had s...

thanks for confirming, it makes sense.

What is the internal config for tmax in our C2
It's apparently 810 nits AFAIK. 990 nits for the G2.
Mine measures around 815-825 nits IIRC.

Re: Dolby Vision now possible through MP4 Mux.

I dont know much about calibration (i paid someone to calibrate my TV) but maybe in TV-LED, only the internal TV DV configuration is used and the EDID target brightness is ignored?? And the EDID is only useful to the player when it does LLDV? That would explain the odd result I see when I use high ...

Re: Witness 4K Timecode Issues?

Since it plays fine in players I doubt Arrow would do anything about it. MakeMKV is pretty strict with timestamps when merging Dolby Vision tracks into one, where it drops a lot data if the two videos don't match as they should. It shouldn't be dropping anything when possible but not much that can b...

Re: Witness 4K Timecode Issues?

The disc has authoring issues. It seems the timestamps in the m2ts are different for both tracks, but the underlying bitstreams have the same timestamps. So when MakeMKV remuxes, it uses/copies the container TS which are wrong. You can get broken timestamps by remuxing the m2ts with MKVToolNix as we...

Not true TV-LED and no 24fps support.
The new stick 4K Max 2nd edition (2023) does do 24 fps now.
But not much has changed otherwise, though others report all lossless passthrough to work with Kodi.

According to Plex it's supposed to support DTS too.

@quietvoid, can you explain your method ? Or send a link where I can learn about it? Thanks!
I don't provide support, it's in VapourSynth: https://github.com/OpusGang/awsmfunc/bl ... e.py#L1905

Re: Dolby Vision now possible through MP4 Mux.

Did you check the whole clip ?? its just some random frame that flashes. The first flash happens at frame 68. if yes then I don't see how its possible and why its happening ONLY with the transformers movies. As I said I checked hundred of movies with the same avs script. Yes I see them with DoviBak...

Re: Dolby Vision now possible through MP4 Mux.

strange that it's happening only with the two Transformers movies. I also tried directly from the untouched m2ts. It looks like the rpu mapping flashes with the homemade FEL test files. sample: https://drive.google.com/file/d/1BzPm7zZqWF0hq1Y3UWe9Rnit7IsObwix/view?usp=sharing I can't reproduce the ...

@quietvoid since you're using your own method and not the DV baker, have you ever had this issue?

this is Transformers.Dark.of.the.Moon.2011
No, sample?
FWIW DoviBaker is missing implementation details which make it unusable for profile 5 files, so it's possible some profile 7 also have issues.

Then don't forget to inject the original FEL RPU back into the HEVC file output from Staxrip/x265.exe after that compression process is complete.
Huh? No, you're supposed to be using a profile 8.1 RPU in the final video.

I think they just want to make sure that the DV logo pops up, even if the content is just SDR. The Ahsoka show, Barbie are below 400nits most of the time.
400 nits is not SDR, and the image doesn't have to be bright all the time to be HDR.
Ahsoka looks nice and it's graded to 600 nits.

Re: Dolby Vision now possible through MP4 Mux.

It's usually HDR10+ that has more random changes in the metadata, like flashes. Dolby Vision always relies on the shots and flashes don't cause new metadata because the shots are predetermined when editing/grading. I don't think HDR10+ actually lets you align everything to shots, the process is too ...

Re: Dolby Vision now possible through MP4 Mux.

It seems, for some reason, the dovi_tool can't generate a rpu from a Resolve hdr10plus json directly but if you just inject the resolve json to an hevc file and then extract it to a new json file, it works. Resolve generates HDR10+ metadata with SceneFirstFrameIndex starting at 86400, while it's cu...
