Dolby Vision now possible through MP4 Mux.

RESET_9999, I've seen and downloaded the new DoVi test files, but I don't know what means the L1, L2, L3, L8 terms, please could explain to me in short or redirect to any post which explain it so I could test in my Chromecast with Google TV.
Thanks in advance.

see: https://www.youtube.com/watch?v=hOhnxXnrauI and https://professionalsupport.dolby.com/s ... uage=en_US
check if you see a reaction for L1/L2/L8 in LLDV/TV-LED

Tests made on Chromecast with Google TV over both TV-LED and Player-LED modes.
I have played the eight "RPU p8.1/4 L1.L2..._cmv29/cmv40" files.

I can't see any change in picture in L2_trim_chroma_weight, L2_ms_weight, nor any L3 and L8 tests.

Please, can you explain to me what this means? It suposses any problem to Dolby Vision FEL/MEL processing on this device?

Thanks in advance RESET_9999.

We've just discovered a bug withe Zidoo Z9X Dolby Vision output. Using the DV test pattern from here:

https://www.biaslighting.com/products/s ... -reference

the Zidoo Z9X will only resolve black levels down to 85. The Nvidia Shield has been tested and it correctly resolves all the way down to 64, as does my LG C9 internal player. It would be interesting to see which devices pass the test and which ones don't.

Sadly real world viewing shows this problem as posterisation in dark scenes and is very distracting.

This is expected and it means the CCwGTV (or your TV, but unlikely as you said it's the same in player-led mode) only supports CM v2.9 Dolby Vision.

That pattern isn't free but we've had it for a while and it just shows some issues with HDMI input devices.
I thought the Shield also had the issue, though.
The FireTV Stick 4K (2018 and 2021) clips at 72 on LG C8-C2, assuming your pattern is the same as what we've had.

You can try the same pattern but with modified metadata from RESET_9999's test files: black.levels.pattern.modified_3079.ts
If that improves the black clipping, then it's the same issue.

interesting...
x800m2 is crushed/clipped at 72-73 on the C8 but on the C2, it's perfect, I can see 65/66.

@to anyone doing Hybrid P8 remux, I started an excel sheet listing the movies that can(or can't) be injected:

BvS Dawn of Justice IMAX should be good IIRC - 4K nits UHD

Death on the Nile (2022) No good 1k nits UHD

Black Widow UHD (with non-IMAX DV5) No good 1k nits UHD

i cant inject aquaman imax hdr10 with madvr. it cant played in my tv with mp4 dolbymux container.
Mastering display luminance : min: 0.0050 cd/m2, max: 4000 cd/m2

OK so with black.levels.pattern.modified_3079.ts the Z9X goes down to about level 67. What exactly does this mean and what does issues with the HDMI input devices mean?

Edit. Could adjusting the DV block in the EDID help?

It means you're dealing with the same issue we've seen before, and it only affects this test pattern.
It's probably a bug in the Dolby Vision processing of the TV, because the pattern uses 10 000 nits for the mastering display metadata.

In actual content, you would have similar black level to 67, so everything's fine.

Except that in real world content I can see the black crush. I’ll post up some photos to show what I’m seeing - this has been confirmed by others as well

Hi Guys!
Could someone pls tell me what i do wrong when trying to "repack" mkv p8 to mp4 p8 using RESET_9999's DoVi scripts?
I got smth like this

looks like it's trying to convert lossless audio to EAC3 but your file doesnt have lossless audio. I'll have a look.

right now you could just demux your file with mkvextract and then use workflow 1 and input HEVC + EAC3 + SRT

thx for a quick response!
i'll will give it a try a little later.

btw when i drop extracted HEVC file into mediainfo it says simple HDR. But after I remuxed it with tsmuxer mediainfo states DoVi.

I was hoping to play it in mp4 with internal TVplayer because the latter is too clumsy with m2ts (troublesome audio track changing and forwarding). And as we know Sony-800m2 in its turn does not give us eac3(

[realbabilu]

The Profile 8 dovi usually detected as HDR10 only when extracted using mkvcleaver.
To get detected as Dovi, it need mp4muxer or Dovi_script (that includes mp4muxer, and added srt as txt timed using mp4box), or subler if you have a mac.
Not all internal TV knew how to open the added subtitle inside mp4 (as apple standard).
For me, i still prefer using Dovi_script or mp4muxer alone to get only video and audio track as mp4 file, and leave the subtitle as .SRT extension, the other subtitle as .ASS extension, the other PGS as .SUP file extension, with same name file (diff extension), with nikse subtitle edit free software

I'm trying to convert MKV P5 to TS using DOVI_scripts so I can play it on LG CX.

I select 5 (MODE B) DOVI batch muxer then drag and drop a file.
Audio and video gets converted correctly, but SRT file gets converted to PGS format which is not supported by LG CX.

Is there any workflow which can accomplish what I can want or should I use tsmuxer manually?

[RESET_9999]

Audio and video gets converted correctly, but SRT file gets converted to PGS format which is not supported by LG CX.

ts/m2ts container only support pgs subtitles. You can demux all the SRT subtitles with mkvextract and name them the same as the TS file and PLEX will pick it up.
