Dolby Vision now possible through MP4 Mux.

Bitrate usually trumps anything else, but YMMV.

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.

That completely makes sense. Thank you.

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?

[RESET_9999]

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.

P7 FEL > P5 > P7 MEL = P8 > HDR10plus > HDR10 > SDR

P7 fel is 12bit so it is better than the P5 10bit colorspace.
P8 has the same dynamic metadata but only 10bit colors.

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

None.
I can play the original FEL P7 on my x800m2.

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.

For National Lampoon's Vacation 1983 one.

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

[fransalas]

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

[RESET_9999]

I guess you meant HDR to SDR? You should ask your question about that in the madvr thread.

Do you/we have any idea why they're doing this?
Is it better to just watch in HDR instead of DV for movies with FEL expansion if a FEL compatible player isn't an option?
Would it be possible to re-write the L1/L2 metadata so it's corrected/"unexpanded"?

4 options:
1- just watch in HDR10
2- bake the EL into the BL
3- generate a proper RPU in resolve for the BL actual brightness.
4- get a proper player

Expanding the brightness makes sense actually. It futureproofs the grade for when the TV will be brighter and it makes the content accurate on more type(brightness, HDR format) of display.

Because this way, people with brighter DV TV(G3) can enjoy brighter HDR and people with low nits DV TV can also get an accurate picture thanks to the trim pass and L1.
Then, people with HDR10-only TVs (low nits) can also get an accurate image with the 1000nits BL. If the BL was as bright as the EL, then those low-nits HDR10 TVs would look bad/clipped.

For a UHD BD like Back to the Future with both Expand Brightness FEL and HDR10+, do you feel it would be better to convert HDR10+ to DoVi with your tools or generate an RPU in Resolve?
