Dolby Vision now possible through MP4 Mux.

All of my recent DaVinci Resolve generated RPUs have a min_pq value of 0. This includes variable aspect ratio files as well as cropped files. Am I doing something wrong?

Did you plot L1 ? because if you just look at a random frame with the dovi_tool it can be hard to find one.
If you did your blanking(or timeline resolution) correctly it should not be always 0

I can see the values changing within Resolve.

I'm still working on getting the script to run correctly.

reset_9999 deserves his own topic with his revolutunary tool. it's sad for newcomers to start in this topic that is already outdated.

I'm still working on getting the script to run correctly.

yes, it's not easy to install, I struggled myself.

you have to install python and a couple of modules.
https://www.python.org/downloads/

you can install a module(ijson in that case) by typing this in a cmd window

Code: Select all

pip install ijson

Got it! Thanks for your help.

@Reset_9999

Would it be possible to have a video.mkv.measurements file as an input file?

[RESET_9999]

6-2-2 can do that.

6-2-2 can do that.

This workflow allows an already generated .measurements file? It's asking me for a video file. I'll have to get back to my workstation to get the error.

[RESET_9999]

ha yes, I introduced a bug for that in the latest versions. you can try the older versions as 1.5.8, and it should work.
will fix next time

the muxing time of shooter and the godfather untouched bluray is very short, and the end TS file is only between 13GB and 17GB. what is the reason for this? (4-1-1)

i've selected the longest mpls file. i'm sure of that.

[RESET_9999]

i've selected the longest mpls file. i'm sure of that.

I doubt that because I just tried Shooter BD and there are two 20min small playlists and the main movie one.
I took the right one and got a normal 44gb TS.

So either you're out of HDD space on your output path or you selected the wrong playlist.

Does this comparison look typical? HDR10 Resolve generated DV.

yes, as you can see madvr min_pq is always 0 which makes avg_PQ inaccurate.
Resolve's scene cut detection is also substantially better than madvr. With madVR, there will be (sometimes) one shot very bright and the next one(within the same scene) darker. I never had this issue with Resolve.

I’ve come to the conclusion that if we re analyze a movie that’s already graded scene by scene technically we are producing a diff graded result as well.(bc color decisions are being decided by present graded elements)
& that’s why they are diff types of analysis modes some of us have only experienced 1type of analysis mode.

[RESET_9999]

100% non-sense.
L1 metadata generation is just pixels brightness measurement(this is what the dovi L1 plot is). When you set your resolve project correctly you don't touch the original grade. it's like working with the master.
You could export it to 422 and then re-encode it to x265 and it would still be the same grade(unless you start playing with the colors and brightness).
