Dolby Vision now possible through MP4 Mux.
Re: Dolby Vision now possible through MP4 Mux.
Hi! 7) MODE.M4= MP4_MUXER Workflows / 4) MODE.4= Apple iOS compatible MP4 after my iPhone 12 Pro max why is the screen green? https://radikal.host/i/photo.1wEtX
Re: Dolby Vision now possible through MP4 Mux.
It's most likely caused by the additional mapping data in FEL RPU.legosoff wrote: ↑Sun Sep 25, 2022 1:55 pmHi! 7) MODE.M4= MP4_MUXER Workflows / 4) MODE.4= Apple iOS compatible MP4 after my iPhone 12 Pro max why is the screen green? https://radikal.host/i/photo.1wEtX
I'm not sure if RESET_9999 's script supports "remove_mapping", you may need to wait for his guidance.sw5163 wrote: ↑Tue Sep 06, 2022 12:28 amI think those are caused by processing "reshaping data" in RPU (polynomial, and MMR mapping).
From my understanding, P5 RPU has "reshaping data" for ICtCp->YCbCr.
P8.1 RPU doesn't need "reshaping data" for HDR10->HDR10.
P8.4 RPU has "reshaping data" for HLG->PQ.
P7 RPU has "reshaping data" for processing the weird colour in EL (I'm not sure what it really does)
MPV can adapt those polynomial, and MMR mapping for ICtCp->YCbCr, HLG->HDR10 etc.
However, it can't process EL and merge that with BL like proper dolby decoding engine.
Resulting in wrongly processing those "reshaping data" on BL.
I think RPU consists ("reshaping data" for colour space transformation) + (Levels for brightness/contrast trimming)
So you can see some artifacts when scene/brightness change, but it's wrong.
And MPV just abandons all the brightness/contrast trimming.
It’s also probably the reason why it’s so important to “remove_mapping” when converting FEL->MEL
I'm not sure about this, please point out my mistakes, many thanks.
If not, you can also do it manually https://www.avsforum.com/threads/apple- ... n.3252865/

Re: Dolby Vision now possible through MP4 Mux.
yes, all the workflows except the manual one remove the mapping.( hevc input workflow 1: since I didn't expect someone to input raw p7 hevc, i dont even remember adding support for p7 there lol)
His file looks like a real profile 5 though. I don't have any apple devices so I can't help him.

Thanks for the reply.

Re: Dolby Vision now possible through MP4 Mux.
if 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...

Re: Dolby Vision now possible through MP4 Mux.
Hi 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?

Hi, I'm kind of new to this script, and every time I try to measure something (HDR10, HDR10Plus or DoVi) I get many errors. I don't know why, since I'm pretty sure I installed all the required py modules. Anyway, this is the log file:

mediainfo ( text view / HDR format):

you only need to know that information when you are using Workflow.1 (manual). the other workflows auto-detect the input profile.

Re: Dolby Vision now possible through MP4 Mux.
interesting, it fails when it tries to save the data into a graph, I have never seen that error and I didn't write that python script so I can't really help you here.( I assure you it's working on my PC)
did you install this version of color science?

Re: Dolby Vision now possible through MP4 Mux.
Sorry, can you clarify what you mean? The phrasing of your answer seems to imply that it doesn't matter that it's 1080p, but I was hoping to hear more about it.RESET_9999 wrote: ↑Mon Sep 26, 2022 4:18 pmyou only have to edit L5.hell001 wrote: ↑Mon Sep 26, 2022 3:46 pmHi all.

Re: Dolby Vision now possible through MP4 Mux.
You can use my script (Mode.I / Workflow.1) and choose the automatic L5(when the script ask you)...
or
manually:
You convert the RPU to profile 8 as usual and you edit L5 to match the 4k video. E.G. if the 4k video has an active area of 1600px then L5 is:
Code: Select all
{
"mode": 3,
"active_area": {
"crop": false,
"presets": [
{
"id": 0,
"left": 0,
"right": 0,
"top": 280,
"bottom": 280
}
],
"edits": {
"all": 0
}
}
}

Re: Dolby Vision now possible through MP4 Mux.
Thank you, I'll check that out. I've made hybrids before, but not one where the quality on the DV source is different, so I was thrown off. Out of curiosity, what would be the difference if I simply had the 2160p DV layer? Would both layers produce the exact same thing, or is there slight quality loss with the 1080p layer?RESET_9999 wrote: ↑Mon Sep 26, 2022 4:34 pmYou can use my script (Mode.I / Worlflow.1) and choose the automatic L5(when the script ask you)...

i'm now always converting my mkv file to ts and then i use you' re program, if there is only one hevc file in the container. is this the correct way? (4-2-3)
