Dolby Vision Support in JRVR
danbez:
Answering my own question:
I verified that JRVR does indeed consume the DV dynamic metadata for both profile 5 and 7. I used the samples from this link on my test:
https://www.avsforum.com/threads/dune-pro-vision-4k-dolby-vision-fel-and-rpu-response-other-random-stuff.3188469/
The only scenario not supported yet is FEL (full enhancement layer). @Hendrik any plans to support FEL in the near future? While in theory FEL shouldn't really be that important, some titles are taking advantage of FEL to fix problems with the base layer - elevated black levels, chroma issues, etc. Examples are Total Recall, Annihilation, Invasion of Body Snatchers among others.
Hendrik:
JRVR uses the metadata from all supported DV profiles - however, it does not use all of the data. It uses DV data to produce a better HDR image, but does not use the DV tonemapping data to create a better SDR image (yet).
FEL support is complicated, and not likely be "near future".
danbez:
Thanks Hendrik! It's interesting that the DV metadata is not yet used when tone mapping to SDR - using the DV7 samples I posted above, I can still see that the DV metadata impacted the SDR output (in a good way)- and a completely different result when the same file is tone mapped by a solution that is not DV aware (such as MadVR).
That led me to assume that at least some of the DV metadata was carried over to the SDR tone mapping process as well.
Cheers
Hendrik:
Well, it uses one piece of data - the current dynamic indicated brightness, which helps the tonemapping. But not the more advanced data.

Thinking of upgrading to MC29
I am not familiar with all the geek speak so please forgive my question.
Will MC29 play downloaded Dolby vision using bit streaming??
