Can someone share their experience of using FLAC in Dolby Vision mp4? I have a 2.0 PCM audio which I'd like to convert to FLAC.
eac3to does it perfectly, here's the result

Code: Select all

Then I feed it to Mp4Box for a final demux and the FLAC track looks like that MediaInfo

Channel(s), Channel layout, Compression mode, Bit depth values are not being displayed in final mp4. And the Codec ID may not be correct, I think it should be A_FLAC.

Does Mp4Box remove those values or structure of mp4 container doesn't like those particular metadata lines? All other audio formats (DTS, DTS-HD, AC3) retain their parameters within .mp4 container, but not FLAC?

New interesting sample
Totall Recall
Shuttle landing scene
This particular scene was encoded by disk makers with extremely low bitrate - about 1.5 mbits for base layer
BL+EL combined are about 40% more
You won't find such difference anywhere else!
Do you want to see EL impact? - Here it is

Files for testing: https://gofile.io/d/G4kmDd

using the v0.0.4_BETA_TEST_17102020 method for movies with truehd audio seems to work for now. It is a much longer process than v0.0.4_GAMMA_07112020 but no audio delay issues with truehd audio.

Yeah, but if you need a mkv at the end, I found with quite a few titles that the Dolby vision layers / dual video tracks end up out of sync with beta - which is a lot worse than the audio

making mkv using makemkv right ? after demuxing the MEL BL_EL_RPU file and muxing them in tsmuxer to iso?
how do you check that the DV layers end up out of sync or not?

Been hearing some pretty negative things about this release over at the blu-ray forums. It sounds like it wasn't a very good encode by the StudioCanal folks. Let's see what the Lionsgate release (assuming it's a different encode) in two weeks looks like.

Shuttle scene is atrocious indeed
But with this sample I see more film grain back in DV and it works like dithering for poor-encoded BL
DV looks noticably better than HDR10

Few observastion from sample without conclusions
DLST is identical to DLDT on UBP-X700
DLST on Shield has noticably lower PQ in compare to UBP-X700

Btw Lionsgate uses SC encode

And another sample
Grinch (FEL) https://gofile.io/d/WO2j3E
This is CG without any film grain to test gradient quality
There is a nice day time change around 1 min mark with red to blue sky gradient
Shield demonstrates pixalisation

Correct. Makemkv will tell you that the two layers are out of sync, seems to always occur at just after the 47 minute mark (duration of the file). If makemkv doesn’t warn you about it, you should be fine. It’s pretty obvious when it happens as makemkv suppressed the warning due too many of them.

It will still complete fine, but then when you try to watch the file, once you get to 47 minutes, as the layers are out of sync, the video just starts flashing constantly.

Has been discussed in one of these topics somewhere - the only way to avoid it for now is to use Gamma. That said, it only happened on 4/5 titles I tried so you might be okay with some.

ok thanks will keep an eye out for it, so far I have only done 3-4 titles total and all have turned out fine as I watched each of them from start to finish.

Hi guys,

just got the new lg cx.
it's still good follow the instructions in the begin #1 of this thread ? ac3 + mp4 method (works well with my c8). thanks

Afraid not. Dual layer playback in mp4 method on CX was removed / never even existed on CX to begin with.

We ran some tests a few weeks ago:

thats a shame... another way to run it ? or it's still not possible. thank you !

[userr]

is there a "step-up" variant of Sony X700? I guess X800M2?
Does either of these, or any other players that are similar/identical in playback, have plexintegration in any way?

ah that's a bummer if the lionsgate release will be using the same encode. SC is notorious for these kind of releases where the base layer is just plain bad and then they try to salvage it with these huge FELs

Hey there, I want to convert a DTDL MP4 to MKV, and I'm on a Mac with no Windows partition. Is this possible to do just in OSX or will I need to run a VM at some point? I tried to use some of the command line tools in this thread using Parallels but everything being mapped to virtual network drives made CMD uncooperative and I just couldn't wrap my head around how to fix it.

Also, I have a Sony A8H that will play MEL conversions fine through Plex, and a Shield 2019 Pro that plays the FELs, but obviously there's still issues to be resolved with the Shield. My 2nd question is thus, are FEL to MEL conversions played by a TV's onboard player known to be any more or less accurate in playback than a straight FEL .mkv via the Shield at this point?

Any intel is appreciated, thanks to everyone working hard in this thread to get this stuff working.
