I created the dolby vision file using the remux mkv version. I’m downloading the full disc version and will try remuxing again using the m2ts file to see if it makes any difference.

Re: Dolby Vision now possible through MP4 Mux.
I tested with American Psycho and it wasn't as pronounced difference as I thought. Can you suggest me some titles?Grencola wrote: ↑Wed May 01, 2019 11:22 pmGlad you like it Yes, it keeps the original file.
let me know what you think of the lossy audio! I found that unless you have a high-end speaker system, it's really not that much worse, while the difference from hdr10 to DV is immense depending on the film.
I have a descent Klipsch 5.1 system with a SVS sub. The 640kbs limit is a little low for my liking. While I rarely hit the 20mbit with lossless, often it hangs around 3-5mbit. So no way to get DD+ with mp4 then and stuck to 640? It's not a show stopper as some Netflix titles I have seen are 192kbs but the DV was stunning.

Re: Dolby Vision now possible through MP4 Mux.
Ah, different firmware on the C6 than the C7 I guess :/ Also, you managed to convert Justice League from the remux mkv? everytime I try it gives me random errors that I've never seen before, figured I need the m2ts.

Re: Dolby Vision now possible through MP4 Mux.
yea American Psycho (and definitely some others) have lackluster DV (and hdr10 even for that matter), but others like Tomb Raider, Mission Impossible, and most movies that have quite dark / bright scenes etc. look amazing in DV.bgalakazam wrote: ↑Thu May 02, 2019 5:34 pmI tested with American Psycho and it wasn't as pronounced difference as I thought.

Unless you luck out and the movie contains an eac3+atmos track, the best you can put into these mp4's with public tools is non-atmos 1536kbps DD+ eac3 audio. my app can't do that conversion as the program needed doesn't run from a command line, but if you follow the steps at the beginning of this forum it's pretty simple to do it yourself. it does sound better, too. the 640kbps audio is more for people without surround systems or ones of low to avg sound quality..

Re: Dolby Vision now possible through MP4 Mux.
I just started following this thread, but why is exactly that you can't use the lossless atmos track with the video? Does something break if you add the audio to the muxed mp4 with ffmpeg?

Re: Dolby Vision now possible through MP4 Mux.
Thanks. I tried the Xmedia Recode per steps in page 5, but ended up with a single track .eac3 file and not a .dts so nothing to demux.
Can I use this file to mux with dlb_mp4base or do I need a .ac3 file? If the latter, can I just rename the file or I need to redo the whole process? (don't have demuxed HEVC streams right now to test).
Sorry for the silly questions, while IT and computers is my career field this is the first time I do deeper A/V mux/demux and recoding. End of the day, if I can get a 1.5Mbit DD+ with DV in MP4, I can live with that for those titles.
Code: Select all
Format : E-AC-3

Re: Dolby Vision now possible through MP4 Mux.
You should run the eac3 file through TSMuxer demux anyway just in case, it only takes a second. it will be an ac3 file, yet it secretly stores the original .dts track inside causing mp4muxer to error. it still may spit out two files, it always did for me anyway. unless you somehow managed to make XMedia Recode convert without retaining the original track, mediainfo does appear that way, but I could never find that setting. then ya, after that just use it with mp4muxer like you would an ac3 file since it can handle ec3 files just fine.bgalakazam wrote: ↑Thu May 02, 2019 8:50 pmThanks.

Re: Dolby Vision now possible through MP4 Mux.
The best an MP4 container can handle is Dolby Digital Plus, so lossless audio is a no go.mrhollywood wrote: ↑Thu May 02, 2019 7:08 pmI just started following this thread, but why is exactly that you can't use the lossless atmos track with the video?
ffmpeg doesn't support ddplus+atmos. There's currently no public software available to do it, either you get lucky and grab it from a movie that already has it, or you buy a licensed copy of Dolby Media Encoder (https://www.dolby.com/us/en/professiona ... lient.html) for a few thousand bux and author your own file.Does something break if you add the audio to the muxed mp4 with ffmpeg?

I almost done the DV versions for 30+ files, but i did it mostly from m2ts (i think 90%).
The only problem is that sometime tsmuxergui (2.6.12) is unable to extract 2hevc+1audio tracks at the same time.
The solution for this is to extract one by one all the tracks you want to use.
Re: Dolby Vision now possible through MP4 Mux.
ok thx, I'll use the m2ts for justice league I guess.
Nicely done! Have you tried it with a file on a usb hdd? Although my hdd is usb 3.0, I only have usb 2.0 port and it takes over 10hrs sometimes using my internal hdd takes less than 2 hours.I almost done the DV versions for 30+ files, but i did it mostly from m2ts (i think 90%).
That's why I stopped using tsmuxer and switched to eac3to.. or you know, just use my app and click one button: https://bit.ly/2WbHZR0The only problem is that sometime tsmuxergui (2.6.12) is unable to extract 2hevc+1audio tracks at the same time.

Also, I see that French is your preferred language, let me know if you'd like French subtitles as I can write you a quick mod to add an srt file along with the new mp4

Usually i extract the hevc and audio files from m2ts to my system disk (SSD). This takes about 15-20 minutes.
Then for a standard movie (2h15 50GB) it takes less than 30 minutes to mux the mp4.
Then 10 minutes to move the mp4 file to the nas.

Re: Dolby Vision now possible through MP4 Mux.
EDIT: had to rename .eac3 to .ec3 and it worked. No need to demux after the DTS -> DDP recode with Xmedia, just rename the file.
Grencola, I need your advice if you have actually gotten DD+ to play correctly. Running eac3to or your program plays DV and 640 DD no issue. When I did a DTS track convert, my receiver Denon X2100W detects the DD+, Sony X700 detects and shows the 1.5mbit rate, but there is no sound. My process was: rip DTS -> Xmedia to DD+ .eac3 file -> TSmuxer demux same track to .ac3 -> mp4base to mux to MP4.
Was my error demuxing .eac3 to .ac3? If that is it, should I have just renamed the file for mp4base to take it correctly?
Have you successfully muxed a 1.5 DD+ track with DV to a MP4 that played back correctly? If so, can you give me the exact steps? If not, I am back to choosing between lossless audio + HDR10 vs 640kbit + DV

Re: Dolby Vision now possible through MP4 Mux.
Of course I've 'actually' gotten it to work :p I would never give detailed steps on how to do something without making sure it works first. it sounds like you're doing it right, I'm not sure where you went wrong. you don't rename any extension, you just demux the dts file Xmedia spits out and it should split apart the dd+ ac3 track from the dts one so you can just delete the dts track and mp4mux the dd+ audio. maybe it's an AVR / BDP glitch? this guy seems to have an AVR doing the same thing:bgalakazam wrote: ↑Fri May 03, 2019 8:31 pmGrencola, I need your advice if you have actually gotten DD+ to play correctly.

My AVR is an Onkyo, maybe it's one of the lucky ones that can decode 1536kbps eac3?
Also you should do this though anyway, as Xmedia doesn't blend the rear channels in so you technically don't get true 5.1, I never got around to trying it:
if Xmedia worked from cmd line my program would already do this method.Mouth_of_Sauron wrote: ↑Thu Feb 21, 2019 1:35 am
- eac3to will mix the back channels into the surrounds when creating a 5.1 track from a 7.1 original, however it doesn't appear to be able to encode to EAC3. So the best you can get is 640kbps AC3.
I'm new to this stuff but I believe the following will work to create a proper 1563kbps 5.1 track from a 7.1 TrueHD original:
- Xmedia Recode can encode to 1536kbps 5.1 EAC3, but doesn't mix the back channels into the surround channels when converting from 7.1. As a result you lose the back channels.
Use eac3to to create a 5.1 lossless FLAC file with the -down6 switch which appears to mix the back channels into the surrounds, you can then convert the 5.1 FLAC to 1536kbps 5.1 EAC3 using Xmedia Recode with direct channel mapping.
Obviously you still lose Atmos, but it at least gives you high bitrate EAC3 with a proper mix down of the side and back channels.
Presumably this would work the same with a 7.1 DTS-HD MA original too.
