Hello, I've tried latest DoVI scripts (1.4.6).

Did the following:
1. Extracted all scripts and tools to C:\Temp\Dovi_Scripts
2. Commented out Dolby Encoder because I don't have it (line 59) ::set DEE_path=D:\other\DEE5.2.0\dee.exe
3. set tsmuxer.popup=YES and mkvtoolnix.popup=NO
4. Started .bat file and pointed it to network share

I did the following workflow 1-7-2-2

What happened is that whole TEMP folder was completely deleted.
This was an error message:
The process cannot access the file because it is being used by another process.
The system cannot find the path specified.

I didn't have anything critical in Temp folder so complete disaster was avoided (thank god I didn't run it from Program files).

But why it did delete the folder below where scripts are run (it also deleted scripts and folder itself).
yeah do not place the dovi_scripts folder into a folder named TEMP because the script will always delete it. The script make a folder called TEMP for the temporary file in the same drive you place the doviscript folder and when the script is done, it delete the temp folder.

C:\Dovi_Scripts or C:\folder.not.named.temp\Dovi_Scripts
(thank god I didn't run it from Program files).
lol

I've read the source of the script and seen that it's hardcoded to temp folder for every workflow.
I think you should put disclaimer in the readme that temp folder will be erased.

And it would be great if temp folder could be parametrized like output folder :)

The only problem I see with this method is that the static MDL metadata seems messed up now.
What's that? Will that cause a problem in DV play? If it doesn't affect final image, I wouldn't bother to change it.
Mastering display luminance : min: 19.6608 cd/m2, max: 4000 cd/m2
MasteringDisplay_Luminance_Original : min: 0.0050 cd/m2, max: 4000 cd/m2
Use hdr=none when muxing.
Unfortunately, "hdr=none" cause the LPCM audio to play as stereo so I guess Apple users will have to live with the messed-up static MDL.
the ATV is REALLY picky!!!

I think I found a huge bug on the x700/ x800m2 / C2, even worse than the red push or the lack of FEL support :(
The L1 brightness changes are totally different than the C2 internal plex and the Shield(which have newer DV engine) but L2 looks exactly the same on all the devices.
By different I mean they are much much less noticeable on the x700/ x800m2 . like 400% difference, no exaggeration. Even less noticeable than Windows 10 HDR10 P8 playback lol.

If you take the out-of-sync version of the Spears and Munsil clip, because the trim passes are active with L1 at the same time, you can barely see a difference between all the devices.
But if you strip out the trims by generating new metadata with madVR (just L1), then again a big difference in the L1 brightness changes.
Tried MP4 / TS, and it makes no difference.cmv2.9, cmv4.0, old mp4muxer, new mp4muxer.

maybe the newer DV engine of the C2/shield vs the older one from x700/x800m2 cause the issue?
I guess I have to connect my old C8 to find out...

pattern to reproduce:
quietvoid's rpu test: https://drive.google.com/file/d/1hAv4eJ ... sp=sharing
SM clip out of sync original: https://drive.google.com/file/d/1BxsK7- ... sp=sharing
SM clip out of sync no L2 (madvr): https://drive.google.com/file/d/1CuWlHK ... sp=sharing

########################################################################################################################
EDIT: no issue on the C8 + x700/x800m2 vs internal player, L1 changes as pronounced as on the C2/shield.
so it looks like there's something going on when using a CMv2.9 HDMI device to a CMv4.0 TV... Or maybe just something with my C2, I hope people with C1,CX will do the same test
I guess I just lost fel and lossless audio support :(

bug confirmed on:

LG C2 + x700 + x800m2
LG G2 + oppo: viewtopic.php?p=124746#p124746
LG C1 + x800m2: viewtopic.php?p=124868#p124868
LG C9 + x700: viewtopic.php?p=124959#p124959
Sony X900H + x800m2 https://www.avsforum.com/threads/offici ... t-61832553

This stuff is incredibly confusing...

If you can explain the test I can test using both an LG CX and LG C1.

Regardless ... does this mean the "chinoppo"/oppo are pretty much the best players?

I dont know about the oppo but we're about to find out. please try quietvoid's rpu test file and compare the L1 reaction with your oppo and TVs internal player. If it's as different as my C2, you cant miss it.

if it's not just an issue related to the C2 only, I expect the same issue because I think the oppo and the x700 have the same SOC.

ok - thanks ... I'll give it a test tomorrow on my CX and C1.

By the way, do you prefer the x800m2 instead of the oppo 203 (or clone) ?

Do you have an example of this behaviour? Are the changes just subtle instead?

The only thing I noticed is that the C2 internal player clipped white brighter than external HDMI devices.

I never owned an oppo (or clone). But if I had to choose I would go for the x800m2 because of DT-DL TS support without any bug.
And I'm not a fan of BDMV folders or ISO storage (not practical) but that's just my opinion and if it turns out the oppo doesnt have the bug described in these videos, I will get one for sure.

sure, here are videos showing exactly what I'm talking about. There's clearly something wrong.
I'm curious about your firestick...

Sony X800m2 (so dim that you almost can't see it for L1):

That is so weird, but Apple is stupid so it's hard to tell.

Good spot, yes, same with Oppo (set to TV-led) and G2 (different than internal Plex).
You also mentioned FEL, what about it? I guess you mean internal players, just checked the Spartacus-Gladiator mix FEL on the Oppo and it works fine.

You know they overcomplicated the spec when there is no single player which plays all DV profiles in all containers without bugs.
