Dolby Vision now possible through MP4 Mux.

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.

it doesn't matter how big the frame difference is. It's fine as long as your source scene cuts are in sync.

I just watched your corelect configuration tutorial. Why is L6 set to Discard instead of Source?

[RESET_9999]

L6 is useless

[HotFudge]

yes, L2 is always ignored with a cmv4.0 RPU + hardware, even without L8.

Hi Reset

So does this mean in order to use my generated DaVinci Resolve RPU
I need to save it as v2.9 for it to use the L2 generated trims since
if I save the RPU as v4.0 it will just use the "empty" L8 v4.0 trim and
ignore the L2 generated v4.0 trims?

[RESET_9999]

No, as I said, the generated L2 trim is meant to mimic the improved tone mapping of CMv4.0 on CMv2.9 devices.
CMv4.0 L1 + L3 is roughly equivalent to CMv2.9 L1 + L2.

Ah sorry RESET.

I think I get it now
For cmv4.0
if L8 is empty then it will use L1+L3 generated metadata otherwise it will use L1+L8.

Thanks very much for your continue help.

[RESET_9999]

if L8 is active, it will use L1+L3+L8. Check out these metadata video comparisons: https://drive.google.com/drive/folders/ ... dMiy2ka0mf

RESET you are MVP

Thanks again

L6 is useless

why is this metadata useless?

[RESET_9999]

it's not used in DV

[HotFudge]

Interesting. Thanks

Hmm then what's the point of making it a setting in cpm build?

[RESET_9999]

For the same reason my scripts automatically edit it when injecting XML even though it's useless, why not?
Just enable it if it makes you feel better...
