Re: Dolby Vision now possible through MP4 Mux.

Post by Amused »

Hey guys,

I am newbie here and this is my first post on this forum.

I have the Sony x700 and the Zidoo Z1000 Pro. My tv is the Sony 77A80J OLED.

I am trying to play a Dolby Vision FEL encoded MKV file through the Sony X700, but it shows only Black screen and freezes up.

I then tried to convert the DoVi FEL MKV file to M2TS file via tsmuxer because I read somewhere that the Sony X700 can read DoVi FEL M2TS files, and then I tried to play that file on the X700. However it doesn’t play - black screen again. It works only if turn off Dolby Vision on the X700, but in that case I only get HDR10.

Is there a way to convert that MKV file to M2TS or some other type of file and then play it on the Sony X700 while utilizing the full fat DoVi format?

Assuming players are all Nvidia Shield, is there any benefit to converting P7 to P8?

The Shield discards the EL and plays back with RPU data when playing P7, which is nice. Does DoviScripts P7 to P8 conversion bring anything from the EL into the BL or is it discarded during conversion?

EL is discarded and P8 playback is much more reliable on the Shield.

you can use the script in my signature.
mux BL.hevc, EL.hevc and audio.THD+ac3 in tsmuxer and enjoy FEL DV on the x700.

Thank you, will do so!

The .gif you posted says that the workflow expects the first file to be video and the second to be audio (the Atmos track I assume). In my MKV file the second file is not the Atmos track. If that is the case, should I first recomposition the files within the MKV container and, if yes, which program should I use to do that?

Many thanks

Well, in that case, you could just select a workflow that doesnt convert the audio and convert the audio separately with eac3to.
https://www.videohelp.com/software/eac3to

The best workflow is to use the original BD in the first place instead of a P7 MKV.

FYI, audio conversion is only needed when TrueHD is in an MKV container.
So when your input has DTS-HD or if the input is an original BD, no audio conversion is required

Hello,
I've just ripped Westworld S01 UHDs and have several questions about it.
Judging by DV EL bitrate (120 kb/s) it looks like a P7 MEL release, but seems to be encoded as a P7 FEL (reported by MakeMKV and DoVi Scripts_1.4.7/dovitool). I'm not an expert in the DV metadata info and just demuxed the S01E01 track into BL+RPU+EL. RPU is 18mb and EL is 58mb. When converted to MKV and played back, the EL-only track seems to look like a standard MEL - just plain grey image for the whole duration of the file. I've uploaded EL and RPU https://www.dropbox.com/sh/154396onvqld ... mG1Ja?dl=0. Would appreciate it very much, if somebody more knowledgeable could take a look what's really going on in these DV layers and if it's safe to just convert it to P8 without loosing anything (for archival purposes). Thanks a lot!

Which workflow do you recommend in that case?

I couldn’t find version 1.4.8 of your script on the link in you signature, where can it be downloaded?

in each mode, there's always one workflow that doesnt touch the audio at all.
1.4.7 is the right version. I'm always one version ahead.

Westworld is MEL

Extract only the EL HEVC stream off any p7 UHD and put it into an mkv container and play it, if it's all green on playback it's MEL, if it's grey/white and you see motion artifacts (usually reddish and greenish squares here and there) it's FEL, as you did.

All p7 is FEL technically IIRC, it's the UHD DV delivery profile/package, MEL is a sub type of FEL between 'real' FEL and MEL, so to speak

Ok, I did another comparison. I can say for sure that there IS a difference between the internal player and the x800m2 with the MEL DV Spears and Munsil clip.
The internal player clearly pushes red and yellow more(similar to what we see on the shield with the red push and before you ask, there are no red spots on the doctor sleep sample :) ).
In some scenes, the brightness is exactly the same, in some other scenes it's a bit darker, and in other scenes, it's brighter which points to the L1 issue, I think.

So in this video, I recorded both clips separately with my DSLR camera using the same setting with the auto-exposure locked. Then I just synced and put them side by side in Premiere.
Left= internal player Right= x800m2
https://www.youtube.com/watch?v=KTsZqpOpO38

now, which one is correct? I still don't know but I'll compare a lot more content this way.
and here are a couple of screenshot comparisons from the original videos (easier to see the brightness difference):

I looked at the screenshot comparisons and to me x800m2 is only marginally brighter than internal player in some, and look the same in the rest.

Anyway, this whole Dolby Vision situation is sad. It's supposed to be the standard, yet inconsistency remains and it's very hard to get an answer out of Dolby. Have you heard about Dolby Vision gaming on Xbox? It upscales sdr/hdr games to fake Dolby Vision... What??? How can Dolby allow shit like that to happen? And don't get me even started on Dolby Vision support on PC.

What are the alternatives to the x700/X800m2 I wonder? Compared to other devices, those players seem to be the most complete solution - can handle all types of Dolby vision layer files and internal subtitles with very few drawbacks. I can't use PLEX because my internet speed is below 100Mbps. And do you know if this Dolby Vision issue is exclusive to usb playback or it expands to disc version as well?

Great, so FEL it is then. EL is grey and looks pretty static to me (no color squares or silhouettes to be seen), maybe it's doing very basic corrections ... My assumption was (because of ultra low bitrate of 120kb/s) that it is a FEL-encoded empty EL (like with MEL). Thanks.

hey guys

i have an interesting conundrum, i have got The Craft UHD and this one when i use the MP4 option it seems to choose the wrong audio format, the movie has a DTS-HD Master 5.1 and a 2 CH and it seems to only choose the 2 channel one and its frustrating me like crazy, how do i get around this and choose the 5.1 version,

do i have to use another option that i have to demux it and then compile or as a suggestion to add to the script, can we have the choice for the audio track before we choose the Subtitle before it then starts the composition?

I disagree, the difference is not marginal and this is exactly the kind of difference i was expecting. Of course it wont be as drastic as in the patterns because L2 works properly.
Now the color saturation is bigger problem I think and don't know which one is right.
sure the x700 supports FEL, but FEL is unnoticeable 99% of the time.
You dont need an internet connection at all to stream local rip, btw. The wifi is fast enough but i use an usb to giagbit ethernet adaptor.
