Hi everyone!
Lately I've been imagining videos with profile 8 that played on my Sony TV have some lowering of the Frame.
So I went looking in the DoviScript menus to find something that could fix this very annoying problem.
The function is there! And it's the fps fix (2-1-3).
However, I am curious to know if this problem is caused by something wrong on the part of whoever injects profile 8 into the video.
Can you tell me something?
Thank you!
EDIT:
By any chance, is there a way to understand if the frame needs to be adjusted even before watching the video?
I'm not sure how changing the fps would make the file works on Sony TVs. I thought they only supported P5?
If you get the older version of my script, there were workflows that could make fake ''p5'' file from p8 that should works.

My Sony TV plays all profiles up to 7 Mel from mkv. More than stable. Lately I've been taking profile 8 material (which didn't have any problems until some time ago) in which I notice fluidity problems. Problems that are totally solved with your script, running the "fix frame".
Only 20% of videos with Dolby Vision 8, from my web source, have this problem (with my TV, maybe with other devices it goes smoothly) and I was wondering if it was a problem of the person who injects Dolby Vision, maybe he made a mistake some settings.

ha I see.
Then the problematic files are most likely P8 hybrid from iTunes...
Those webdl are missing the framerate bitstream information and this is what the script fixes.

In fact, now that you mention it, the problem showed up on all episodes of the Foundation, AppleTV series

Why do none of the encoders seem to care that there may be brightness grading differences between the p5 and hdr10 streams?
Yeah, and since P5 RPU needs to be extracted to hybrid P8.1 either way, why they just don't bother to release the original P5 file?

The chinese group you are referring to only releases itunes p5s?
I don't know, they seem to have a PT website, I can't play with PT, all I grab are their BT leaks.
I haven't seen them release P5 other than itunes source, but maybe because I'm not paying very much attention.

Not from any other source?
I'm not as knowledgeable as you guys here, there is another streaming service provides P5? Movies Anywhere?

Don't itunes p5s have screwed up colors?
Sometimes they release a V2 and color seems fine. But again, there might be other problem as I said above, so I'm still looking for more trusted group. Btw, does DVSUX still exist after the shutdown of rarbg? I really miss their releases.
I saw a few people say that DVSUX is no longer doing releases. I can't confirm that though. I have no idea. And yea, it's crazy that they don't also release the P5 versions since they're required for P8 conversion lol.

Why scene cuts different in HDR10+ and DV version?
I'm not sure but...
In Dolby vision, sometimes the flashes (single frame) can have their own scene cut which doesn't seem to cause any problem at playback (I tested that with my own rpu).
In HDR10plus, I read somewhere that the metadata can only change at a real scene cut or otherwise, it can cause issues.

More logistically, the HDR10+ could have been provided by different source for the streaming platform or requested for streaming only, as it is likely upcoming UHD BD will only have DV from Warner Bros.
It's usually HDR10+ that has more random changes in the metadata, like flashes.
Dolby Vision always relies on the shots and flashes don't cause new metadata because the shots are predetermined when editing/grading.
I don't think HDR10+ actually lets you align everything to shots, the process is too automated.
Well, I have definitely seen flashes as a single shot in retail DV source...
The Bad Guys animation movie is one I remember because it confused me when I did my P8 hybrid remux.

*** I think I found an issue with the x800m2:
1- DTS-HD 2.0 plays only as lossy DTS (core)
Is this bug still present with the X800M2? I tried playing a DTS-HD MA 2.0 track and my receiver reported DTS-HD MA, not DTS. However, I have no clue if the X800M2 is doing something weird like wrapping the lossy DTS core in a DTS-HD MA container on the fly. How did you find this bug? Is there a test file with a silent core to easily verify what is being played?
Thanks!
it might be a thing with my AVR. The osd reports only DTS while with 5.1/7.1 tracks it reports DTS-HD.
It could also be related to the network playback , I don't think I ever tried via USB.
Interesting. I’m playing through network as well. Both the X800M2 and my AVR report DTS-HD MA on a 2.0 track.

Yes. I’ve seen that as well on my own rip of Arrow’s Cinema Paradiso DV UHD disc.

Yeah, I've also seen that. I'm guessing (some? many?) DoVi shot lists are at least initially coming from an automatic algo pass (especially since v4.0 from Dolby), as it would save anyone doing the grading a huge amount of time/labour, even if they do a second manual pass after to delete/add further, and they either just leave the very short "flash" shots in or don't even notice them, lol.

There are even flashes in some HDR10 releases... The 2017 US Lionsgate UHD BD of La La Land (2016) even has flashes in its HDR10 BL. Only the 2022 IT Eagle UHD BD of La La Land (2016) fixes this issue in its Base Layer (it also has P7 FEL), but the Base Layer of that release appears to be extremely problematic and requires the FEL for expanded brightness, and the L2 Trims to correct the saturation.

Then it must be my AVR (its quite old) and maybe it was the same on my x700 and I just never noticed.
I know that the ffmpeg DDP 1536kbps track doesn't work on the x800m2 and I'm certain they worked on the x700. The EAE 7.1 DDP tracks play fine.
Does anyone know if it's possible to get 10k nit with CM v4.0 like these?
I'm asking because whatever mastering display I choose with 3-1 (Professional CM v4.0 Dolby Algo) I get lesser results, maximum 1k, 2k or 4k nits. 10k nits doesn't seem available. Is there a reason for this or?
Do the guys above have access to tools we don't or does Dovi_scripts just not allow 10k nits (yet)?
