Re: Dolby Vision now possible through MP4 Mux.
option 1 (lossless but can be unstable)
mkv P7 input: 7-2-3
bdmv input: 7-2-2
option 2 (quality loss when input is FEL but 100% stable)
mkv P7 input: 4-2-2
bdmv input: 4-1-1

Re: Dolby Vision now possible through MP4 Mux.
As far as I was aware, all DV layers are 1080p. I'm sure someone will correct me if I am wrong...hell001 wrote: ↑Mon Sep 26, 2022 3:46 pmHi all. Stupid question here, but is there a difference between a 1080p DV layer and 2160p DV layer? There is a release I am trying to hybridize and I have the 4K HDR, but only have access to the 1080p Profile 5 DV. Does anyone have any experience with something like that?
Cheers

bluray disc folder yes. 7-4-2 or 7-4-3 excellent. no problem.kazuma wrote: ↑Mon Sep 26, 2022 4:02 pmhow do i know when it is a profile 7 file?RESET_9999 wrote: ↑Mon Sep 26, 2022 12:51 pmif your input is a bluray disc folder yes. 7-4-2 or 7-4-3
if it's a P7 mkv then use 7-4-4 or 7-4-5
7-4-1 is only for when you want to mux raw P5/P8 HEVC,AC3,EC3,SRT...
But one mkv problem dvhe.08.06, BL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 7-4-4 after that, the green screen again. How do I fix it on profile 7? Thank you.
Re: Dolby Vision now possible through MP4 Mux.
For MEL discs I have been using this to discard the EL layer and create a base RPU for mp4 encoding.
This thread says that FEL discs need an additional step to remove_mapping that strips out the additional EL processing.
https://github.com/quietvoid/dovi_tool/discussions/168
Can anyone confirm this is needed on FEL discs?
I ran both approaches (discard vs remove_mapping) on a FEL disc and the json metadata was quite different.
Code: Select all
dovi_tool -m 2 convert --discard video.hevc

Can anyone confirm this is needed on FEL discs?
Code: Select all
fel_to_p81.json
{
"mode": 2,
"remove_mapping": true
}
dovi_tool --edit-config fel_to_p81.json mux --bl bl.hevc --el el.hevc --discard

Re: Dolby Vision now possible through MP4 Mux.
mapping removal is only for Profile 7 input. When input is P8, my script assumes that the mapping was already removed.
I'll check if i can add support for p8 that still have the mapping

Re: Dolby Vision now possible through MP4 Mux.
yes thats correct and you should always remove the mapping for FEL to p8

Re: Dolby Vision now possible through MP4 Mux.
I get you, you're right. These films of his were ready on 08.06, BL + RU, apparently there is a problem, and the other films that are there are working fine. It's most dvh.08.06, BL+RU someone did it wrong. I decide to download the Blu-ray disc, solely trusting myself.RESET_9999 wrote: ↑Tue Sep 27, 2022 3:45 pmmapping removal is only for Profile 7 input.

Re: Dolby Vision now possible through MP4 Mux.
You can just manually remove those additional mapping in that p8 file, saves the redownloading time.
Sometimes I find it difficult to remux Blu-ray disc when there is a single video stream that consists of multiple m2ts files.
So I actually prefer FEL remux version.
Only the first part and remove_mapping of that post is useful, the rest part regarding MMR and polynomial mapping discussion is just me being stupid, please ignore. But I would like to express my thanks to @quietvoid and @RESET_9999 and you all, really teach me a lot.Ibuprofen wrote: ↑Tue Sep 27, 2022 3:12 pmThis thread says that FEL discs need an additional step to remove_mapping that strips out the additional EL processing.

Re: Dolby Vision now possible through MP4 Mux.
You could manually fix it as @sw5163 said but starting from the original untouched disc is always the best workflow.
Well, that's a bad idea because most of the remux from seamless branching discs on torrent are done incorrectly with makemkv or mkvtoolnix.
The only way to properly remux seamless disc is with DGdemux or Tsmuxer.
btw in my script, you won't even know when the disc is seamless branching, the whole process is automated regardless of the disc.

Re: Dolby Vision now possible through MP4 Mux.
What do you mean by that? Are you suggesting that the way MakeMKV mashes segments together is wrong in some way?RESET_9999 wrote: ↑Tue Sep 27, 2022 5:56 pmWell, that's a bad idea because most of the remux from seamless branching discs on torrent are done incorrectly with makemkv or mkvtoolnix.

Re: Dolby Vision now possible through MP4 Mux.
yes unless makemkv was updated, It doesnt remove the gap in the lossless audio track which can cause some playback problems.

Yes, it has already been done, 7 profile is being executed after 7/4/4, the green screen is still again.RESET_9999 wrote: ↑Tue Sep 27, 2022 5:56 pmYou could manually fix it as @sw5163 said but starting from the original untouched disc is always the best workflow.
