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 .

update to the latest one:
https://github.com/quietvoid/dovi_tool/ ... /tag/2.0.2

Thank you, that fixed it!

nop, none that I know.

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.

Thanks for the reassurance.

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

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.

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.

Thanks for the tip. I have the US UHD.

oh by 4 frames you meant the script complained about a framecount mismatch when injecting the RPU??
if yes, then it is normal to have a framecount mismatch because it's rarely the same as the WEB-DL. What matter is if the rpu scene cut match your bluray scene cut.

Or is that a specific process I can run with the tool?

workflow is (2-4) and check the animated gif ("Verify DV synchronization.gif") in the tutorial folder.

No, I opened the created MKV in StaxRip to verify the frame count of the MKV. I also ran the 2-2 workflow to view the frame count of the RPU. I noticed the four frame distance and then when running the 1-1 Hybrd workflow, I re-synced the RPU by removing 4 frames.

Thanks very much, I will check that one out! I had no idea it existed. Thank you.

I see, then you didn't have to remove 4 frames. You still should always verify sync with (2-4)

Thanks again for all the help today. I will verify with 2-4 and try again. Thanks so much.
