H.265 HEVC is lossy codec. Period.
But that is literally what UHD Discs use..

Grencola, I recently got Atmos stuff. So back to this, any way to do DV with lossy Atmos? I know there is ATV4K solution, but I only have a Sony X700.
If you try what I said above, I bet the x700 would play it. the full uhd-bd bdmv rip, dvdfab, and tsmuxer is all you would need.

I’ve said that several times to you when we discussed on DV. It’s a common knowledge here.
Doesn’t change the fact that the codec is lossy.

Cool man. UHD Blurays are encoded with a lossy codec. I got it. 8) Anyway, imho, getting Dolby Vision AND 5000+ kbps Lossless audio+Atmos with a few megabits of video compression is waay better than having those 3 or 4 Mbps back but hearing 640kbps ac3, lol. If what I even said will work, I mean. Otherwise of course go with the lossless mp4 vs lossy mp4.

Yes, but you can't see the difference between this encode of 48,2 Mb/s or the remux of 52,7 Mb/s. I have been comparing it several times. Maybe this is a nice solution for tv's that don't play dual layer mp4.
Well, whether the difference is visible or not is different topic. And this is very dependent in viewing environment, equipment and viewer.
That's not true at all; HEVC is NOT just a lossy codec. It can be perfectly lossless. In fact, Blurays use HEVC :) This is also such minor compression, we're talking a few mbits, that he's right, you won't see that. Plus the benefit could be a HUGE; what's now stopping us from demuxing the new single layer dv video track, and then muxing it with the hd-audio + atmos track into a ts container to now get full playback we've been wanting without an Oppo?! Apple TV 4k running MrMC, the Sony X700 BDP, and some TV's with e-arc can playback dolby vision from single layer video files and they support hd audio. I'm pretty excited! :D
Tsmuxer doesn't reconize the single layer dvhe video track, so i can't mux it with the TrueHD Atmos audio track. Is there an other muxer to try with?

Do you mean when demuxing? This: https://github.com/DolbyLaboratories/dl ... 64bits.exe will demux your mp4 and give you the single-layer video.hevc track. Then add that to tsmuxer. If you did that and you meant it isn't recognized (weird cuz it should be) then ffmpeg should work.

I suggest using mkvtoolnix. Just change the extension to mp4 before muxing.

it would be something similar to this:

Code: Select all

 
ffmpeg -i <audio-stream> -i <video-stream> -async 1 -c copy test.ts
I haven't used ffmpeg much though, so those triggers might not be right

Hmm, I just thought all hope is lost according to Grencola's comment. I don't trust Sony and Kodi won't get license. However, if DVDFab can indeed convert dual layer DV into single layer DV, then Sony TV might have a chance. But, how is it possible?

the only method was needing a Dolby CMU Workstation with Dolby Encoder Suite and an official license from Dolby to reauthor the film into a different container. Not entirely sure how DVDFab achieves this. I personally haven't been successful yet, but I'm also only using the trial version as I didn't want to spend hundreds of dollars if it doesn't actually work.

If your TV can play the single layer LG DV demos files then you might have a chance..

Hi guys,

how to make an .mp4 dolby vision file from full blu ray iso using clonebd ?

Donpablo80 where is the compression mode in dvdfab?

I use the trial and have only 3 attempts and i used 2

1º time I used the Passtrought MP4 and create a MP4 with dual layer DV, the 2º attempt I used the MP4 Dolby Vision and is very very rare, it takes long time and is a Passtrought too.

Where is the option in the menu what do you say?
