CMV4.0:
No idea why they completely changed the algo for avg_pq. max_pq is indeed higher but it doesn't make a big difference in reality.
raising the avg_pq floor from 2.5 to 10nits makes the low end slightly brighter but avg_pq almost has no effect when the RPU source_pq is 1000nits.
I wonder whether the contemporary mastering monitors at the time of Dolby developing the Content Mapping versions is related to the avg_pq floor being raised between specs... I'm guessing the standard mastering display was likely a BVM-X300 OLED when the CMv2.9 spec was developed, and then a BVM-HX310 LCD by the time the CMv4 spec was being developed.
Also, I'm guessing they raised the avg_pq floor for optimized viewing on uncalibrated consumer displays since most either crush or wash out shadows.
It would be amazing if Dolby were more open about this stuff.
I'm aware a much higher bit rate is better than a lower bit rate, but I was asking about HDR specifically.
Ignoring the bit rate, what HDR offers the best quality? Does P5 DV offer features P7 DV doesn't have (besides a slightly more efficient colour space)? Does P8 (HDR10/HDR10+ and DV) offer any features P5 / P7 doesn't have?
IPTPQc2 is better when it's encoded straight from the 12bit master. The colorspace is more efficient and retains more color information which in the end is the equivalent of 11.5bits YCbCr(exceeding our tv capabilities btw).
There's no point/benefit in going from 10bit YUV to IPTPQc2.
With the option to encode to SDR included in your script (6-9), do you still prefer to use Resolve? Is (6-9) SDR only for P7 DV that expands the brightness?

I prefer Resolve to tone map HDR to SDR because you can use the official 100nits trim pass from the rpu.
SDR encoding in 6-9 is very basic, it use libplacebo default settings.

As far as DV FEL that expands the brightness, do you prefer to bake in the EL or to generate DV with Resolve?

Does somebody knows if there's a list or sheet online which has information on all UHD DV discs including the amount of "nits" ?
Because some of them are mastered in 1000nits and some in 4000nits.
Hi, RESET_9999 any way I can contact you regarding a doubt on one of your grade/master check list as "not sure!" , I have the itunes WEB DV P5 untouched, and wanted to see about injecting it to an UHD.

I don't know, I measured the movie with Resolve and MadVR and the peaks max + avg look higher on the WEB-DL. It could be close enough (that's why it's in the ''not sure'' section).
Good afternoon, I'm using an online translator since my English is not very good, someone would be so kind to tell me where is the route to put the tools and tell me what tools I need because I think I need some ... if you could send me a private message I would appreciate it...... Thank you
Thank you very much for answering me RESET_9999 I do not know what happens to me that I can not send private messages. I have another question in the adtuality I have an NVidia 4090 I have to activate something if I want to pass an SDR to HDR10?.. Thank you
