yes, you have to disable smooth gradation. This setting removes fine details anyway.

Will try it again with smooth gradation off when I'm back from work later tonight.

Did the comparison again with smooth gradation off but it doesn't change anything. I hardly see any difference between the HDR10 sample files and the Dovi ones.

Are you watching in a dark room?
Near black Posterization and banding on LG OLED TVs is a well-known issue, and many people have moved to QD-OLED Samsung because of that. My Samsung monitor and Hisense LED TV don't have any of those LG issues.

Yes I'm watching in a dark room. The sun was down for hours and there were no lights.
Guess I still got a good one from LG :)

I would never move to Samsung by the way. A company that doesn't support Dolby Vision can't take my money.

@RESET_9999

For Nosferatu (2024), if my cmv 2.9 bluray version is extended cut and your cmv 4.0 RPU is theatrical then they won't work together, right?

I'm not reset, but that's correct. It will work up until the first extra/added scene, and then everything will be out of sync thereafter.

I actually didn't see the problem because the problem was not there for me at that time :-)

I had my TV calibrated yesterday and now in the calibrated picture I can clearly see the banding in ''The Martian'' sample in HDR10.
BUT this goes away for 90% by setting smooth gradation to LOW.

In Dolby Vision there is no banding - also with smooth gradation OFF.

Yeah, I'm hearing the same from the G5. It's a good thing we can generate DV for everything.

In the HDR10+ injection workflow the delay doesn't get applied.

Here are the original scene cuts:

Code: Select all

"SceneInfoSummary": {
    "SceneFirstFrameIndex": [
      0,
      24,
      144,
      180,
      300,
      336,
      456,
      492,
      612,
      4213,
      4232,
      4514,
      4561,
      4669,
      4884,
      5120,
And here are the "synced" scene cuts:

Code: Select all

"SceneInfoSummary": {
    "SceneFirstFrameIndex": [
      0,
      24,
      144,
      180,
      300,
      336,
      456,
      492,
      612,
      4213,
      4232,
      4514,
      4561,
      4669,
      4884,
      5120,

May it be a problem in the script that delays HDR10+ metadata?

I dont know, works fine for me when I check the new scene cuts in 2-1 and I get the framecount mismatch at injection..
Duplicating frame one, 24 times...
Warning: mismatched lengths. video 2876, HDR10+ JSON 2900

You have to check the injected/extracted json . This was the method used before hdr10plus_tool added native resync support. Hdr10plus tool recalculates the scene at injection.
If you get the latest beta and update hdr10plus_tool, you should be able to check sync directly with the edited json.

Not pc gaming though.
