Dolby Vision now possible through MP4 Mux.

So I just used the .ts video (https://drive.google.com/file/d/1hAv4eJ ... sp=sharing) you posted on avsforum to test on my c9.
The image changes very differently on the c9's internal player compared to the x700, for both L1 and L2. Even worse is during the brief black screen transition, it's completely black on the internal player, but on the x700 there are two grey bands on top and bottom (I notice that in your x800m2 + C2 video as well). I don't know what's going on here.

This sucks. Did I just watch the whole Dolby Vision library with sub optimal image quality? But there's no alternative either.

And people who are testing this on their tv, remember to set the same picture settings for both inputs: your tv's internal player and your bluray player. I'm using Cinema picture mode for both.

interesting result... Sorry for calling you @deadphil earlier, I mixed you up with someone else lol.
As for the grey black bars, it's because the pattern is cropped. You'll get the same issue if you play any cropped content.

Ah ok so the x700 shows grey bars with cropped contents, but the internal player doesn't?

On another note: If I go to the General>About This TV>TV Information and scroll down to Dolby Vision, it says 21.26 there. What is yours on the C2 and C8?

Are there any more tests that I can do? In the last few pages, it seems there are several test videos, quite confusing. Which one should I use?

Btw Jellyfin (opensource "Emby") was recently released for WebOS on 2021-2022 models in LG Appstore!
Install portable on windows:
- download combined portable zip from: https://repo.jellyfin.org/releases/serv ... ws/stable/
- follow: https://jellyfin.org/docs/general/admin ... ion-x86x64
- access the interface via: http://127.0.0.1:8096/
- if an auto connect server is there and you can't connect with it, then just delete that server and refresh the page

batch file:

Code: Select all

cd "%~dp0"
system\jellyfin.exe -d data

I only tried couple of files DoVi mp4 files, those worked, couple of test files didn't, and we can't set the color of subtitle, but nice to have options.

Here are the videos for comparison on my C9:
X700:
https://youtu.be/MC0HxMV3LXM
Small changes with L1. Noticeable changes with L2, except no changes with L2 trim_offset 0.75

Internal player:
https://youtu.be/28TkcoPaUzc
Noticeable changes with L1. Noticeable changes with L2, especially big change with L2 trim_offset 0.75.

I tried RPU p8.1 cmv29 file using Panasonic Oled internal player(new dolby engine) ,Fire Tv Max and Oppo

I noticed brightness deference in L1 and L2_trim_offset 0.75 with Oppo player the internal player and fire tv look the same

[ragico]

Tested cmv29 and cmv40 compatible with Apple TV 4k:

Tested on Lg CX 48" and on Panasonic JZ1000 55".

CMV29
CX internal player and Apple TV connected to CX (same results)
L1 ok
L2 ok (L2 saturation gain and ms weight better on Apple TV)

Panasonic internal player and Atv connected to it, same results as CX

CMV40
CX internal player and Apple Tv connected to CX (same results)
L1 ok
L2 no
L3 min pq offset=no
L3 max pq offset=ok
L8 Ok with exceptions:
ms weight, saturation vector trim 0/1/2/3/4/5 and hue vector field 0/1/2/3/4/5 NO

Panasonic internal player and Atv connected to it, same results as CX

I had a closer look at my C8 now that it's back in the pitch black room and there's also an L1 difference between the x700 and C8 internal player. It's just less obvious and not a night and day difference like on the C2 + x700.
I also tried the Shield + C8 and there's no L1 difference with the TV internal player.

So maybe that bug was always there and because the C2 is much brighter than the C8 now it's just more obvious???

[DiscoD]

Just so we have more data on all playback devices tried the cmv40 File on my Chromecast with Google TV (TV is Vizio m65-F0)
L1 - Good
L2 - Good
L3 - No Reaction at all
L8 - No Reaction at all

might as well get as much data as possible.

Have you guys ever tested convert those p8 to p7 MEL?
It seems only FEL compatible disc players are affected.
Would it be possible these deivices never expect P8 DV and their DV engine always assume there is an EL and treat them like P7?

L2 ok (L2 saturation gain and ms weight better on Apple TV)

That is strange, proper developed internal player should always have more accurate image than external.
Those engineers who built the TV have a much better grasp of the TV specs, therefore should be able to fine tune it.

What is the difference you saw?

[RESET_9999]

What is the difference you saw?

the light changes are slightly brighter on the internal C8 compared to the x700/x800m2.
Not as drastic as on the x700/x800m2 + C2 combo and that's why I didn't really spot it when the C8 was in a brighter room but now in a pitch-black room, I can definitely see a difference.

DoVi version on the G2 is (fw 3.11.35): 31.18
I uploaded the DoVi trim test files (mkv/mp4/ts) into one place (including the latest correct cmv2.9 ones):
https://mega.nz/folder/ehUWVChK#KmxRwARyFogmMWz4nkU6Kg

Yesterday I checked couple of DoVi things:
- internal player (Plex/Jellifyn) is definitely brighter than HDMI devices (Oppo and Shield as well!) with the same files: not just the mid part but also shadow details as well, not sure why
I thought maybe the 1dlut is different, but I used the same settings and the same preset, so the 1dlut should be the same.
I thought maybe Limited/Full (Black level) was the reason, but setting internal players to Full (with bscpylgtv, obviously) we get washed out colors, so that's not that; interestingly this setting didn't have any effect with HDMI devices using DoVi content.
So, not sure what's going on or how this can happen.
Setting AI Picture Pro for Internal players helps a bit to make them similar.

I also checked couple of shows:
Stranger Things s3e2 Plex vs Netflix (both internal): looked the same
Dickinson s3s4 Plex vs Atv (both internal): Atv was darker (this can be because of the metadata in the mp4 file)

So, who knows which are the correct ones

Just quickly tested all 3 files on my C9:

1) DoVi_L1_test_high_brightness_ojA5.ts
Internal player & X700 seem to behave the same

2) RPU p8.1 L1.L2_cmv29-ojmX.ts
Internal player: Noticeable changes with L1 & L2, especially big change with L2 trim_offset 0.75 where the picture looks very wrong - overly bright and oversaturated
X700: Small changes with L1, noticeable changes with L2, except no change with L2 trim_offset 0.75

3) RPU p8.1 L1.L2.L3.L8_cmv40_test.ts
Internal player: Noticeable changes with L1, L3 & L8, no changes with L2
X700: Small changes with L1, noticeable changes with L2, no changes with L3 & L8

So what do I make of this

[sofakng]

I don't want to change the subject, but can I ask a quick question?

Is it possible to convert a DV MEL UHD (dvhe.07.06) to DV 8.0 (or is it 8.1) without any loss of quality?

I'm trying to convert my rip of The Matrix (1999) which MediaInfo reports the following:

Code: Select all

Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2086, HDR10 compatible
