Re: Dolby Vision now possible through MP4 Mux.

@anyone who know something :-) I just don't get it. What is an RPU? And why is an MEL needed when there is no information in it? Why is an RPU needed when you have an FEL? What happens with an FEL when you use yusescope's tool and convert FEL to MEL? Is the information lost? Is it somehow added to ...

Re: Dolby Vision now possible through MP4 Mux.

Excellent analysis, thank you! ... The LLDV bug does not really affect the players... Very opposite LLDV bug is a source-side issue. Any bug-free Player-led source should send DV picture equal to TV-led despite a neglectible brightness difference. Of course if peak brightness value is correct in TV...

Re: Dolby Vision now possible through MP4 Mux.

I believe he's talking about sony tvs, not sony bluray players. correct ... most players can do both DV mode and TV-led capable TVs are not affected by this bug. Also, there's the GoogleTV Chromecast that output lldv by default last time I checked, and no way to force tv-led unless you have an hdfu...

Re: Dolby Vision now possible through MP4 Mux.

I'm not sure what you try to do is correct (injecting p5 RPU into hdr10 streams), and I don't even mean the color issue: it would be correct, if they would use the same mastering process for the streaming and the UHD-BD version. But I think that's not the case. And if the UHD-BD is created in hdr10...

Re: Dolby Vision now possible through MP4 Mux.

I just did myself a DV version of the Star Wars New Hope UHD bluray and it looks great!! Very noticeable upgrade in quality(even on the camera comparison) and the luminance /color looks the same as the original profile 5. So you are taking a streaming/web-dl version of a movie that has an HDR10 bas...

Re: Dolby Vision now possible through MP4 Mux.

Thank you! I read the manual for the tool, but I am confused. Would you mind writing very short examples of combining P5 RPU with HDR10 UHD Disk in the form of script, please? sorry I'm really not the best at explaining things but the cmd-line I used are: convert p5 to p8: dovi_tool.exe -m 3 extrac...

Re: Dolby Vision now possible through MP4 Mux.

Maybe a better comparison would be taking the profile 5 RPU from one of the Disney+ Marvel or Star Wars films I just did myself a DV version of the Star Wars New Hope UHD bluray and it looks great!!

Re: Dolby Vision now possible through MP4 Mux.

I am not sure what the deal is. But my Apple TV 4K ( the previous Gen ) plays P7 MEL and P8 with Plex. What's interesting is, Plex plays P5 files with messed-up green or purple colors lol. Infuse Pro falls back to HDR10 with all profiles, but P5. Anybody knows what's happening, is it Plex magic or h...

Re: Dolby Vision now possible through MP4 Mux.

Would this be somewhat of an expected result? My thinking is that both the Hotstar and Disney+ releases are probably from the same master, just that one is offered at a higher bitrate. Maybe a better comparison would be taking the profile 5 RPU from one of the Disney+ Marvel or Star Wars films and ...

Re: Dolby Vision now possible through MP4 Mux.

So far there has not been any objective comparison between original profile 5 and converted profile 8. Sounds like a challenge for @RESET_9999 and @Mannix if they're still around! The bitrate upgrade in the hybrid may be worth the trouble if the comparisons look relatively similar in terms of brigh...

Re: Dolby Vision now possible through MP4 Mux.

FWIW the profile conversion has been available for a couple months. I just recently added ways to manipulate the metadata enough to be able to get it usable for different video (different length, letterbox bars, etc.) The profile 5 to 8 is still very much experimental, and I'm not even sure if ther...

Re: Dolby Vision now possible through MP4 Mux.

Are you guys aware someone from BHD ( and some other trackers ) came up with a script to use the online WEB-DL DV layer and combine it with a UHD disk HDR10 layer? Like the movies from Disney Plus. It's DV with streaming, but HDR10 with the UHD disks. As I am typing this, I am trying to get my hand...

Re: Dolby Vision now possible through MP4 Mux.

What are the benefits of profile 8.1 instead of profile 7 MEL? Some dovi decoders don't work with P7 but work with P8.1 P8.1 is almost equal to P7 only difference is VUI Chroma Sample Location value. For P7 it's always 2, for P8.1 can be 2 or 0. That's why P8.1 is the best option to convert UHD BR ...

Re: Dolby Vision now possible through MP4 Mux.

Sony XG9505 Since the MEL includes dynamic metadata, it should also still be an improvement over just HDR10, but not quite as good as full FEL playback? Convert to Profile 8. You will not lose that much with dropped FEL. Is it possible to take Bluray profile 7 DTDL and convert it into STSL profile ...
