Dolby Vision now possible through MP4 Mux.

@RESET_9999 What do you think about Auto Generated Dolby Vision?
I mean, usually, behind every grade there's a human eye that checks the grade result often with the supervision of the movie director himself. So my question is: When we do custom grades (auto generated with DaVinci), is the movie director intent of watching the movie preserved? if so, is it really that better than having standard HDR10?

L1 metadata is generated by an algorithm(it just map the hdr grade) and only the L2 trims are done manually so the intended look is preserved.

@RESET_9999 I get an error when trying to plot DV metadata "error: The subcommand 'plot' wasn't recognized". I think I installed all the requirements and hdr10+ plotting works even though it uses the same subcommand. Is there something else I need to do or is this an issue with the script?

Sounds like you are using the old dovi_tool version .

I have an oppo clone and have been making TS files for my hybrids, but I had a thought this morning: Any reason to think that playback would be more reliable with m2ts files given that is the standard on discs?

I really wish we could convert the profile 8 to a profile 7, so we could do create ISOs with full chapter support. That'd be amazing.

Thank you, that fixed it!

nop, none that I know.

if you want to save some time, I already generated DV in resolve for most of the movies, here are over 600 RPU files ready to be injected

Code: Select all

I came across one RPU where the number of frames is 4 frames greater than the mkv I pulled directly off the UHD disc. I went through the Hybrid maker and removed four frames. Is there anything more to it than that? This is the first one I have come across that didn't match exactly, so I wanted to make sure I am not missing something.

By the way, thank you for sharing these. It is amazing.

nothing more to do... which movie is it?

Thanks for the reassurance.

Harry Potter and the Sorcerer's Stone. MKV file made with MakeMKV has 219173 frames.

So, is this generated Dolby Vision really better than having standard HDR10? well, I really though that it couldn't beat the quality of the source file.

Thanks, I just checked mine and it's in sync.
But it is better to always verify the scene cut when you inject someone else RPU.

Of course, you send brightness information(L1 min avg and max) about the content to the TV shot by shot.
So the tone mapping is a lot superior than what you get with the static HDR tone mapping curve because the TV knows in advance how the next shot will be.

When you say "verify the scene cut" do you mean verify the frame counts of the video file and the rpu, like I did? Or is that a specific process I can run with the tool?

Be careful. You need to use US UHD and not EUR UHD. The source for the DV WEB-DL is the American version with Harry Potter and the Sorcerer's Stone, EUR UHD is Harry Potter and the Philosopher's Stone. Some scenes were refilmed between the two versions and therefore DV from one wouldn't exactly match with another.
