Dolby Vision now possible through MP4 Mux.

[FLarnhill]

Are you using some newer MediaInfo version or some old version?

I'm using the MediaInfo provided by my MPC.

For people using DGDemux: when you demux a DV disc, do you retain or not retain the EOS/EOB NALUs? 95% of the time I replace with a cm4.0 RPU, but in some cases, I use the retail RPU. Any recommendation around what to do with EOS/EOB NALUs retain option? Thanks!

EDIT: Another question: Does anyone know what MakeMKV or MKVToolnix's behavior is in this regard? Do they retrain the EOS/EOB NALUs or are they removed from the merged streams?

I do not retain them, so I do not use "-keepeos" flag.

Do we know what is most recommended for ugoos playback?

[FLarnhill]

Hmm, the back of the retail box shows Dolby Vision for sure, so unless it's weird authoring mistake, maybe you should also try and remux from .m2ts using mkvtoolnix or latest DGDemux to confirm?

So, I've done all of this and the same outcome: no DV. Given the fact this movie has a Dolby grade for disc, should it be easier to make a hybrid? Or should I still check the brightness and frame delays?

Could you check the .m2ts file with BDInfo?

Dolby Vision 2

https://www.techpowerup.com/340580/dolb ... y-vision-2

Dolby Laboratories, Inc., a leader in immersive entertainment experiences, today announced Dolby Vision 2, a groundbreaking evolution of its industry-leading picture quality innovation. Hisense is the first TV brand to announce it will bring Dolby Vision 2 to its lineup of premium televisions, such as RGB-MiniLED TVs. This is complemented by the leading French media and entertainment company CANAL+, which has also announced its commitment to support Dolby Vision 2.

For over a decade, Dolby Vision has pushed picture quality forward as the gold standard for premium HDR. Dolby Vision 2 builds on this success and is designed specifically to meet the evolving opportunities of television experiences today, serving as one piece of Dolby's broader mission to advance picture quality across all entertainment and devices, from the biggest to smallest screens.

After reading the entire article, sounds like (from what I can discern so far) more of a beefed up DV IQ - two way tone mapping is (assumingly) talking about matching content to the screen traditionally, and then matching the screen to the environment via camera/light inputs etc. Besides the new things they talk about like auto black/white matching? and motion control!

@RESET_9999

how long does is take to make a RPU for a movie?

[RESET_9999]

With my pc i9 13900ks + RTX 3070 + pci-e gen4 7gbps drives for a 1h30 movie:

prores encoding: 20-25min
scene cut detection: 10min
DV analysis: 10min
injecting remuxing: 6-8min

If I decide to do trim pass(es), then it can take me hours to monitor each shot one by one and make target adjustments

wow, i didn't know it was time-consuming like this with your high-end pc.

Will you implement AV1 codec support in your excellent dovi tool?

no idea, ask on the avsforum thread

May be a dumb question, but I've done a fair amount of research and still don't 100% understand.

In the Dolby Vision Stuff google sheet I see chart "ENCODER GROUPS TO AVOID BECAUSE THEY DONT ENCODE DV FEL PROPERLY"

I have a AM6B+ so I can playback DV Profile 7. I wanted to confirm that I understand encoding correctly. If the group that created an mkv left the file as a Profile 7 release instead of baking the FEL / encoding it into Profile 8, is no encoding actually occurring when the MKV is created from the original bluray disk files? Wouldn't this be a lossless packaging of the data directly into an MKV format?

For example, if a release is titled "███.2025.2160p.UHD.BluRay.REMUX.DV.P7.HDR.ENG.TrueHD.Atmos.7.1.H265-BEN.THE.MEN", does it matter that the release group is in the "avoid" list?

Mediainfo shows "HDR format : Dolby Vision, Version 1.0, Profile 7.6, dvhe.07.06, BL+EL+RPU, no metadata compression, Blu-ray compatible / SMPTE ST 2086, Version HDR10, HDR10 compatible"
