I didn't check HDR10, only Dolby Vision profile 5 for iTunes and HBO Max.RESET_9999 wrote: ↑Tue Apr 19, 2022 2:22 pminteresting. thanks
but are you sure this is what's causing the difference in colors because I see kind of the same difference when I compare HDR10 MA with HDR10 HBO. https://slow.pics/c/axsHELui
MA looks closer to the SDR grade.

Re: Dolby Vision now possible through MP4 Mux.
yes, you're right. I've compared the 3 streaming services P5 web-dl tonemapped to SDR and on itunes, the red looks more orange/brighter. I prefer how it looks on MA and HBO... https://slow.pics/c/MrSz6BQ4
So iTunes does something different in their RPU( i wonder why) and it explains why we couldn't get a match with @manix Atomos Shogun appleTV samples here viewtopic.php?p=111073#p111073
The HDR10 color mismatch from MA and HBO is something else.
Sorry for my English.

I'd guess just 'artistic intent' for whoever authored the DV grade for iTunes encode
Just like they're responsible for their own encode/bitrate level output from what they receive from the studios, places just do what they want with the DV grading too so to speak I suppose

Re: Dolby Vision now possible through MP4 Mux.
Would be true if only this movie had this special re-shapping but its not case, they do that for all the appleTV content as shown here viewtopic.php?p=111073#p111073
Also, a while ago, the ATV4k(itunes) used to tone map DV to HDR10 instead of streaming the HDR10 encode and I always wondered why the red always looked more orange than the other sources. Now i know why.

Re: Dolby Vision now possible through MP4 Mux.
is it just 'artistic intent' across all apple stuff by whoevers authoring it there, title by title; or is it the same exact red push only, same exact metadata values each time, across all their content?RESET_9999 wrote: ↑Thu Apr 21, 2022 3:29 pmWould be true if only this movie had this special re-shapping but its not case, they do that for all the appleTV content as shown here viewtopic.php?p=111073#p111073

Re: Dolby Vision now possible through MP4 Mux.
I didnt check the metadata but yes it is the same red shift on every movie/show. That's why I don't see it as an artistic intent.
But I'll take a look at the metadata now that @quietvoid pointed out where to look.

Re: Dolby Vision now possible through MP4 Mux.
Yes, it looks static for all Apple TV content I've tested.
Usually the pivots are 7, 3, 3 (or really 9, 5, 5), and the value for chroma components is always 0, 288, 224, 224, 287 (pred_pivot_value).
The coefficients for all components also appears to be the same all the time, so Apple might just be doing a static reshape for all their content.
This is also why the non decoded image looks very different to other services.

Re: Dolby Vision now possible through MP4 Mux.
thanks, @quietvoid for confirming, that is what I expected.
IMO it is better to convert any itunes/appletv profile 5 DV to profile 8 .

I'm sure you have already covered this, but whats the benefit of converting to profile 8?

Re: Dolby Vision now possible through MP4 Mux.
I also found another very niche reason but applicable to me - if you use Phillips Hue lights and Hue Sync with your TV (I use Hue Essentials on my Shield in lieu of an official Sync Box) - it works with unprotected DV content like through Plex but it samples just the base layer without any of the color transformation in the DV metadata so it incorrectly just mimics red and greens for p5 files, for p7 and p8 files with HDR10 base layer, appropriate matching colors are output
