Dolby Vision now possible through MP4 Mux.

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

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

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?

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 !

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.

1. I think you can use mkvtoolnix on mac to convert mp4 to mkv, then use MakeMKV to create your DV MKV.
2. Not entirely sure but from comments in these threads, I don't believe they are any/much different.

The MEL conversion played backed on the TV will be more accurate than the playback of the FEL file via the Shield. The Shield has color issues.

I don't know for certain that you can say that the MEL conversion will be more accurate. On the one hand, there are proven issues with color with the Shield even if it's capable of playing FEL. But on the other hand, you are literally removing picture information during the MEL conversion. So then it becomes a comparison of playing a trimmed down video with accurate colors vs playing a full video with inaccurate colors. Even then, it's still bit of a mystery on whether the Shield is really even utilizing all the information of a FEL. Until Nvidia and Dolby completes their investigation on what exactly is happening, just hard to say. I, personally, have just stopped worrying and looking for the color inaccuracies on the Shield. Makemkv and Plex have made things so much easier that I'd rather just enjoy the movie and the lossless audio

If anyone doesn’t believe the color issues on the shield, try Total Recall, it should be the ‘new reference’ movie for red push.
There is more than one clip where the fake frown lines on Johnny Cab are pure red.

On a Mac, one can use MKVToolNix or ffmpeg to remux a MP4 into a MKV container.

I kind of get what you are saying but people in this thread have already done comparisons between FEL and the converted MEL.

The converted MEL will be much closer to the original FEL title played back on a Blu-ray player than the already provenly inaccurate playback of the shield. Since the question is ‘what is more accurate’, I’m certain the converted MEL will be a more accurate representation of the original FEL played back on a Blu-ray player than whatever the Shield is throwing out. Now I suppose we haven’t tested every single title out there so things could still vary.

The shield is undoubtedly the easiest way to playback DV with lossless atmos audio at the moment, but I’d personally rather watch HDR than what the shield produces

I do agree though, at the end of the day we still have no way of playing back FEL DV in an mkv container with 100% accuracy - regardless of audio. All we can do at the moment is compromise to get as close to what the playback should be - that I guess could be a bit opinionated and also have the simplicity / audio requirements aspect added to it.
