Dolby Vision now possible through MP4 Mux.

[redoine322]

Could you plz explain to Me how to get an mp4 or mkv file to work on my LG C1 with DV please using your script From BDMV thanks for your hard Work Sir

Theres tutorial video in my scripts link. check out the bluray to profile 8.1 one.

MODE.P7 ----> MODE.1 ----> Workflow.1
then use tsmuxer nightly to mux the output file with audio. you can edit the bat file with notepad so tsmuxer popup at the end of the process
just make sure there is no pgs sub or lossless audio pre-selected at playback. You can use external SRT subs


You can also use the mp4_muxer mode but it will take much longer time to process and some files may stutter on your C1
MODE.M4 ----> MODE.1 ----> Workflow.3

Thank you for the Reply i did Try that but i got an error here is an Img ( there is plenty of space)

yeah DGdemux wont work if you place the folder on your C:\ drive... do you have another drive you can put the folder on?

Hi guys, Im kinda new to all this so here it goes:

I have some 4K files in p07 that I would love to convert to p8.1 or p5. I saw several messages here but Im kinda lost with this coding and muxes. I was able to instal ffmpeg in my mac (m1) but now i dont know what to do to convert a file. do i need to install anything else? Is there a tutorial for this?

[RESET_9999]

I took a look at the Dolby Vision metadata of The Batman itunes/movies anywhere/HBO and the differences are quite surprising. Itunes RPU is much larger even without L5 and L4. @Quietvoid, any idea why?
Also, why the hell are they all using the old Dolby vision algorithm CMV2.9... CMV4.0 is supposed to be superior, especially for the SDR trim passes. They can do the grade in 4.0 and then export in 2.9 for compatibility reasons though. Another interesting fact about HBO and MA, the colors are not the same(at least for HDR10) but they have the same L1/L2 DV metadata. https://slow.pics/c/axsHELui



The scene around frame 10625
iTunes:
- missing L5
- No L4
- No L6 maxcll/fall
- RPU is considerably larger than the other two
- no full range flag in the HEVC encode

mmmm Last night I watched half of the batman itunes DV WEB-DL and everything was fine.
Tonight I resumed the movie with the MA DV WEB-DL which as stated just above, has incorrect L5 metadata. It is set to 0 when it should be 276,276 (or 275,276 like hbo).

I noticed right away the black bars were not perfectly black like they were last night so I demuxed the rpu, edited L5 properly, injected it back, and voila, black bars are black again.
So this shows how important doing L5 properly is when doing the hybrid remux, especially if you play the movies on your TV internal player.

*** the raised black bars will only happen if a scene has L1 min_pq higher than 0.
*** My TV is in a projector room, so complete black velvet everywhere which makes this kind of issue easy to spot. I would probably never noticed that in a semi-bright room.

Hey whats up @RESET_9999

I've been lurking on here for a while now. I'm pretty much a novice to DV ripping/encoding stuff... With Yusesope's and your help I recently was successful in ripping my first DV movie (.m2ts file) file to DV profile 8 mp4. (So, that I can watch on my LG CX). Thanks!

Since then, Ive been examining a bunch different random DV movies and shows.

So, right before I saw this post, I myself noticed the different sizes of EL/RPU data. I've attached a screenshot of my file sizes. The 1st DV source that was leaked last night had an even larger sized EL/RPU data than the iTunes version. I'm not quite sure where that source came from though. You put down "iTunes, HBOmax, and MA" as the 3 sources you have. Forgive, my ignorance... but what source is "MA"?

Also, what do you make of HBOmax version being a few gigabytes larger in size? What do you make of that? Would that be the best version to watch?
I've attached a screenshot to show you what I got.
If anything that I'm saying is wrong or sound funny please dont hesitate to correct me

[quietvoid]

Itunes RPU is much larger even without L5 and L4. @Quietvoid, any idea why?

Don't know, the info you included is only part of the metadata.

I haven't the Dolby Vision versions (yet), but the Batman films show different aspect ratios in one movie.
I understand setting L5 to 276 would be beneficial to the black bars. But wouldn't it also negatively affect DV playback on where normally the black bars would be, so when video is full frame?
Or is L5 also dynamic, and be adjustable for every scene/frame? If so, forgive my ignorance. I haven't done other with L5 than setting it to zero a couple of times.

yes L5 is dynamic.

[chros]

Nice summary, thanks! I took a quick look at hmax version, but I wasn't blown away by the image quality

[quietvoid]

The iTunes stream has extra chroma reshaping, which makes reds slightly brighter.
https://slow.pics/c/Oa5JZnp6

So the reshaping params take a lot more bytes:

Code: Select all

"num_pivots_minus_2": [
      7,
      3,
      3
]

[RESET_9999]

interesting. thanks

but are you sure this is what's causing the difference in colors because I see kind of the same difference when I compare HDR10 MA with HDR10 HBO. https://slow.pics/c/axsHELui
MA looks closer to the SDR grade.
