Dolby Vision now possible through MP4 Mux.

Your video is missing the framerate at the bitstream level. You can fix it in 9-2
This used to be the case with all the Apple WEB-DL, but now, all the reputable groups fix it.

Hi RESET_9999 ,
Karate Kid Legends has got both DV8 and HDR10+
I want to remove HDR10+ and use your scripts workflow 2-2
Everyhting was done and the resulting file is "Karate Kid Legends_HDR10plus_removed". But why his framerate is 25.000 fps whilst the original movie is 23.976 fps?
Thanks

Reset which workflow to use for the making mp4 5 profile dolby vision from mkv 5 profile dolby vision ?

Dolby Vision can now be included in MP4 files using MP4 Muxing. This advancement allows for high dynamic range (HDR) video content to be distributed more easily while maintaining compatibility and superior visual quality across supported devices and platforms.

May I ask what HYBRID in the title actually means? I thought it meant this version already included DV cmv 4.0 from the web version but upon checking with dovi scripts it does not.

In this example HDR10+ was injected from WEB-DL to UHD Blu-ray remux, which includes DoVi as retail.

Thanks. Wonder why they didn't transfer cmv 4.0 from WEB-DL as well...

why are some movies 4000nits MDL on the disc? and other ones 1000nits? what are the differences?

@RESET_9999 In the case of How to Train Your Dragon (2025), why would the artist put all that effort into a detailed 100nit trim, only to cancel it at 300nits? Feels like a waste of time and effort.

Also, how do the saturation and hue fields work? Are they applied regardless of TV capabilities, or do they target a specific trim?

it's a studio decision to grade movies on 4000 or 1000 nits mastering monitor.

Because the 100-nit trim is delivered for the SDR Blu-ray release. Personally, I like when they explicitly cancel trim interpolation to other targets like that. It shows that the colorist knows what he’s doing and that he wanted the 100-nit trim to be more aggressive while keeping the higher targets intact, since most of this movie sits under 300 nits anyway and don't need tone mapping.

When they apply a strong 100-nit trim, if they push it too far, it can result in higher targets appearing brighter than the HDR master. That doesn’t really make sense, because with a 1000-nit MDL DV grade, those trims will be ignored on TVs with a peak brightness higher than the 1000 nits MDL. So if the 100-nit trim ends up brightening beyond the master, an 800-nit TV could actually show a brighter HDR presentation than a 1000-nit+ TV, which isn’t logical. The whole purpose of trims is to fine-tune tone mapping when the content exceeds the TV’s capabilities, not to make the image brighter than the HDR master itself.

Makes sense.

Do you mind explaining what saturation and hue fields are and how they work? I don't recall you talking about them in your explanation videos. The only thing I know is that they have something to do with colors... and they appear to be set by the colorist during some parts of movies.

[RESET_9999]

They’re essentially just extra fine-tuning colors controls for the colorist during the SDR trim pass creation. I don’t think I’ve ever seen a 600–1000-nit trim that actually makes use of them, but it’s possible.

but what is the benefit of 4000nits over 1000nits? do you get higher brightness on tv's that supports high nits?

[RESET_9999]

That's just the mastering display luminance capabilities used to grade the content. The colorist can grade it as bright as he wants.

Does CM v2.9 vs 4.0 matter for MEL if the max nits are below the capabilities of my display (LG G5)?
Since no tone mapping is occurring it shouldn't make any difference?

yes, cmv2.9 4000nits MDL dims at 150nits even on our G5. Also no black crush in 4.0
