Dolby Vision now possible through MP4 Mux.

Another DV thing I noticed recently. If L5 is missing, the trim's positive lift is ignored on the TVs internal player (and energy player). So it means positive lift will not work for all the AppleTV web-dl on TVs internal player. On the ugoos, it doesn't matter because CPM build generates L5 when it's missing. On all the other HDMI devices, it's always ignored regardless of L5, so positive lift never works.

Positive lift test files:
missing L5: https://drive.google.com/file/d/1QvEgEE ... drive_link
proper L5: https://drive.google.com/file/d/1pQYCYs ... drive_link
L5 set to 0: https://drive.google.com/file/d/1pQYCYs ... drive_link

So CPM build always generates L5 - even when it's missing L5 ?
What does it generate exactly ? Does it use 0 (zero) value in those cases ?

Yes, it sets L5 to zero when missing.
The fact that Positive lift doesn't work is proof that a release without L5 is wrong.

I'm confused, genuinely as I don't know if this is a specific topic for something or if there is something to learn.

I've always used makemkv for movies so far, and have always had DoVi and Atmos support withing the mkv container and just Jellyfin on Shield. Using a Hisense w/ eArc.

Is there something I should be aware of in the future when I want to upgrade to an LG or similar? Seems from the comments the answer is yes.

Or is this about reducing the disc size down and maintaining it?

Do yourself a favor and get the ugoos am6b+. No other player can match its DV quality/capabilities.

I finished adding DV to Avengers Endgame using your best version rpu. Watched the movie and there wasn't any issue. So should it be removed from the Not Sure! yellow table now?

You won't notice any visual defect or anything but when the metadata does not match the BL actual brightness, over-dimming will happen, and unless you know exactly how a specific shot is supposed to look, you won't notice anything wrong.

I explained and showed what would happen and why it is important to check the grades when doing P8 hybrid from two sources.

I see. So will you recommend me continue doing this? Because i'm considering it for the few Chris Nolan movies. They are all hdr10 and in the yellow table.

[RESET_9999]

When in doubt, it's probably safer to use generated DV rpu or watch in HDR10.

I just rewatched your "Transfer CMv 4.0 Dolby Vision from WEB streaming to Profile 7 Bluray disc" video and it only took you less than 2 minutes to extract the rpu from a movie? How is that possible? Mine took like more than an hour.

Hi Reset

Quick question regarding NVidia Shield Pro w.r.t v2.9 and v4.0

Resolve generates automatic L2 100,600,1000 v2.9 compatible trims
but the L8 100 trim equivalent in v4.0 is "empty" (set to 2048).

Will my Shield Pro take the L2 trims? or does it use the "empty" L8 trim.

If your TV also supports cmv4.0, it won't use the L2 trims. The generated cmv2.9 L2 trims are here just to match the newer/updated cmv4.0 algo on cmv2.9 devices; you don't want your player/TV to use them.

Hi Reset

Thanks for your answer

So the L8 trim is used to make manual adjustments to the L2 trims
which are used aslong as it is all in v4.0.

Do you also maintain a list of v2.9 and v4.0 devices and TV's

[RESET_9999]

No, but any hardware made after 2019 should have the cmv4.0 engine

I just did the transfer of cmv4.0 for the movie The Iron Claw (2023). Frame difference is +574. Seems pretty high. Other than that, watched the movie and there wasn't any problem.
