Re: Dolby Vision now possible through MP4 Mux.

Haven't used MP4Muxer in a while, and for some reason now it finishes "processing" immediately and just creates a 0KB file (no error messages). OK, so this just seem to be a problem with The Invisible Man . This is a Universal release with FEL, but Back to the Future is also a Universal r...

Re: Dolby Vision now possible through MP4 Mux.

If you give me such a mp4 I´ll try! I'll make one of these and provide a link, just having a little trouble at the moment though. Haven't used MP4Muxer in a while, and for some reason now it finishes "processing" immediately and just creates a 0KB file (no error messages) - so need to fig...

Re: Dolby Vision now possible through MP4 Mux.

The HDR10 plays without Errors. If you play the EL alone (Ryan) on MPC you see the brightness flashing. Don't know how the RPU can make the brightness pumping playing the DV without EL. Buy private Ryan and test yourself! If U don't believe me. It's not that I don't believe you, and I don't have a ...

Re: Dolby Vision now possible through MP4 Mux.

With the new Firmware CX9 plays DV DL mp4. Tested with James Ryan. I think it's a little dark. edit: it is the same as when I create a DV SL from Private Ryan -> it plays only BL+RPU, not the EL. Picture is falsified :x I think that the TV is not able to decode 2x HEVC at the same time. So the purc...

Re: Dolby Vision now possible through MP4 Mux.

100% Sure. In (rare) films with FEL, such as Private Ryan, omitting the EL leads to errors. In this case, the brightness pumps into bright scenes and dark scenes are far too dark. Otherwise I might not have noticed. where do you get the information from that it can play 2x hevc? But wouldn't leavin...

Re: Dolby Vision now possible through MP4 Mux.

...only the LG OLEDS (mixed report on the current X-generation ones) will be able to play FEL mp4s. @shawnc22 are you able to elaborate at all, or provide a link to more information, about the compatibility of the LG OLED X-Generation? I currently have a C8, but am looking at getting a CX. But I'll...

Re: Dolby Vision now possible through MP4 Mux.

I checked out this thread early on (in the first 10 or so pages) and had success in remuxing DV to MP4, it's been a while and was wondering if anything had changed (without reading all 275 pages). 1. Is this still the only tool that can do this, and when was the last time it was updated? 2. Is there...

Re: Dolby Vision now possible through MP4 Mux.

When I use the Dolby Vision MP4Muxer I find there is heavy HDD activity for a couple of minutes, then a long period of high CPU activity (but little HDD activity), followed by a final period of heavy HDD activity. It appears that it's doing more than a simple remux because of the long period of high...

Re: Dolby Vision now possible through MP4 Mux.

seems like it should work as it remains lossless right up until eac3. I can already make eac3's in XMedia recode but I can't seem to find that surround blending I thought I saw. so your flac trick might be the ticket. and I can do it all from command line so I'd upgrade my code, and make it the ult...

Re: Dolby Vision now possible through MP4 Mux.

OK, from what I can tell the following applies (correct me if I am wrong): 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. Xmedia Recode can encode to 1...

Re: Dolby Vision now possible through MP4 Mux.

When the core is lower than 640 kbps, the encoding is done from the uncompressed track - truehd/atmos, not from the core. So -core is not needed, only -640. Because if the core is already 640 kbps it will be extracted, but if it's lower e.g. 448 or even 224 (Hunter Killer) the output will be encode...

Re: Dolby Vision now possible through MP4 Mux.

I think for higher bitrate eac3's XMedia Recode has a - ex tag where it folds in rear backs? I have to look again I can't remember. I wonder if it too can all be done from a command line because I would definitely change my program to use higher bitrate eac3 instead of lower ac3 and have better sou...

Re: Dolby Vision now possible through MP4 Mux.

Like others, I'm hoping that in the future we might be able to get DV in MKVs. For this reason I'd like to be able to demux the DV MP4s in the future, but when I try tsMuxer doesn't recognise the DV stream so only demuxes the base video and audio. How can I demux a DV MP4 back out into the 3 indivi...

Re: Dolby Vision now possible through MP4 Mux.

You're partially correct however since dolby vision is a 12-bit video and the hdr10 track is only 10-bit I believe that dolby is merging both tracks to turn the 4K track from 10-bit to 12-bit using the dv layer track. The metadata is also there in that track. As for others finding that the dv track...

Re: Dolby Vision now possible through MP4 Mux.

fyi if you type eac3to.exe file_name.m2ts it will list all the tracks. hd-audio is always track 3 if there's dv, otherwise it's track 2.. you would just type: eac3to.exe 00005.m2ts 1: base.hevc 2: dv.hevc 3: audio.ac3 -core -core extracts the core audio, yes.. but naming it a .ac3 file means it wil...
