Dolby Vision now possible through MP4 Mux.

[kazuma]

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?

Do you know the best way to move my coreelec cpm a14 build from the existing usb stick to another usb stick with all the settings intact?

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"

Hello @RESET_9999, could you provide more details about T1-T2-T3-T4 analysis and how it affects metadata, or point to a relevant source?
I tried googling it, quoting it with “resolve studio,” etc., and searching this topic, but I wasn't able to find anything except replacing L1, L2, L3, etc., which doesn't say much.

Thanks !

if it's a remux, it should be fine...
That list is only for the encodes and that guy ben the men encodes are ridiculously bad: https://slow.pics/c/Yp0F0UWf

The release of the recent dim movies (F1, Jurassic World Rebirth, and Superman) got me thinking... Is there any brightness (or lack of) where it would be better to watch the SDR release instead?

As my TV is not professionally calibrated, I think it's still better to go HDR in my situation, as I know the brightness will better match the artist's intent (as opposed to my SDR brightness, which is just eyeballed).

> That list is only for the encodes

Have you found that most releases labeled "remux" are truly lossless remuxes, or do you have to watch out for releases labeled as a remux, but that are actually an encode that has been labeled as a remux that may have some small changed like changing from P7 to P8?

@RESET_9999 do you always generate new Dolby Vision metadata even for CMv2.9 retail P7 with manually done trim passing?

These movies are only dim compared to SDR if you don't watch SDR at reference level (100-150nits). At reference level, the HDR in these movies still win, see my youtube comparisons.

if the filename says remux, it's most likely a remux. P8 ones are probably hybrid with metadata taken from web source.

only the 4000nits MDL ones

only the 4000nits MDL ones

Why is this?

only that causes an issue on my G5:
