Dolby Vision now possible through MP4 Mux.

Yes, any value over the MDL is ignored, and you cannot change the RPU MDL. Modifying it would make everything else inaccurate since Dolby calculates metadata differently based on the MDL.
Also, it ignores any positive lift offset (values over 2048). Used in almost all movies...

[powdeau]

So if the L1 values are higher than MDL, it is better to generate new DV metadata with higher MDL, right?
But what about the Mad Max Fury Road, since I cannot set MDL higher than 4000 in Davinci? Is it than better to watch it in HDR10?

Regarding the positive offset – isn’t it mostly used in 100-nit plots and thus doesn’t have much effect?

BTW Haven’t you changed something in your "Chroma Weight Bug" sheet, since I cannot scroll there anymore?

if the movie constantly goes over 1000nits with a 1000nits MDL, yes.
if it goes over 4000nits, there's nothing you can do about it, it will clip.

No, the positive lift is often found in the 600-1000-nit trim, and the example I just posted is a 600-nit trim.
Even if the positive lift were only in the 100-nit trim, the problem would still exist because the metadata is always extrapolated to any brightness target.

should be fixed now

Thanks, so from your experience, would it look better to watch it in DV with clipping or in just HDR10 without DV?

I don't know, it depends on your TV's handling of the static HDR10 metadata. On my C2, content over 1000nits with a 1000nits HDR10 MDL is also clipped.
Just get a Ugoos instead, it's 10 times better than the x700.

[powdeau]

Do you please have a clipping test in profile 7? Because when I tried your clipping pattern in profile 5, there was no clipping on x700.

[RESET_9999]

all the test files are here: https://drive.google.com/drive/u/1/fold ... JWcWoliuQ4

[powdeau]

Sorry for the wrong information, I have tested only the 1000 MDL file, which doesn't clip in any profile. The 2000 and 4000 do clip.
But it is still weird that the 1000nits MDL doesn't clip.

[RESET_9999]

you tested the wrong files or confused the filename.

white clipping 1000nits MDL (clipped at 1000nits): https://drive.google.com/file/d/1qQPnuB ... drive_link
white clipping 4000nits MDL (clipped at 4000nits): https://drive.google.com/file/d/1zzcrqy ... drive_link
white clipping 10 000nits MDL (no clipping): https://drive.google.com/file/d/10OT1bg ... drive_link
real content (clipped): https://drive.google.com/file/d/1QCxaJU ... drive_link

I have downloaded it again from these links and it is the same - no clipping with 1000nits MDL and neither with real content.
Maybe my TV (G4) completely ignores DV if the MDL is 1000 regardless the actual L1 values.

[RESET_9999]

This doesnt make much sense, the pattern is 10 000nits with 10 000nits L1 and the real content 3000nits with 3000 L1. Are you sure the files trigger DV? We're talking about the x700, right?
It wouldn't make much sense for your TV to clip 4000 MDL but not 1000 MDL. I have a 2 000nits TV much brighter than your G4 and it behaves exactly like the 800nits C2. L1 can only dim, it doesn't brighten the image like the trims can do.

[powdeau]

Yes I'm sure it triggers DV and yes, I play it on x700.

@RESET_9999

I just did cmv 4.0 transfer for A.Quiet.Place.Day.One.2024 and got this error. What is it?

[RESET_9999]

metafier doesnt allow some special characters in filename

[deadchip12]

Do I need to rerun the whole thing with different file name?
