Re: Dolby Vision now possible through MP4 Mux.

Hi all, I've been doing some quite thorough testing with Gemini Man 60fps-DV, so I thought some of you would might be interested in the result, here they are: I encoded the BL with x265, using mostly slow preset and crf17 and I used the encoded file as BL for all my tests. The attempts that didn't w...

Re: Dolby Vision now possible through MP4 Mux.

For this type of experiment, I recommend using the 0.0.4 alfa version of my tool. You're right when you say "it's the EL where all the DV info lives" but keep in mind that the info contained in EL are "calibrated" on those inside BL. If you re-encode BL, logically, you should al...

Re: Dolby Vision now possible through MP4 Mux.

Thanks. One last question, if you saw Doctor Sleep , did you also encountered the problem of the girl's cheeks (as reported HERE ) with your setup and your files? I have that movie with re-encoded BL too (I encoded it with hdr10+ parser so only the bitrate is different once again) and I checked it ...

Re: Dolby Vision now possible through MP4 Mux.

That all sounds logical, but I watched about 20 titles from start to finish all with re-encoded BLs and I've never seen any artifacts. And I used one of the best player+screen (screen was professionally calibrated) combos that is available for DV-testing purposes. I am sincerely happy to read what ...

Re: Dolby Vision now possible through MP4 Mux.

Using the right x265 settings, only the bitrate will be lower but everything else (including the HDR10 metadata) will be the same as in the original BL so I don't see why wouldn't it work. Because (lowering the bitrate) you reduce the amount of information inside BL. EL aims to improve the performa...

Re: Dolby Vision now possible through MP4 Mux.

Is there anyway to use handbrake to compress the base file before using your special tool? For this type of experiment, I recommend using the 0.0.4 alfa version of my tool. You're right when you say "it's the EL where all the DV info lives" but keep in mind that the info contained in EL a...

Re: Dolby Vision now possible through MP4 Mux.

Creed II worked like a charm, even after converting it to .TS, it triggers DolbyVision on my LG C8. Unfortunately The Meg doesn't work: yusesope's tool creates the BL+EL+RPU.hevc file successfully (all counters are 100%) but neither Dolby's mp4muxer nor TSmuxer can mux it for some reason. mp4muxer ...

Re: Dolby Vision now possible through MP4 Mux.

I tried yusesope's tool (v 0.02) with "The Meg" but for some reason it didn't work. Process finished and asked me to exit with "EL analysis" being at 99% and the resulting hevc file has the exact same size as the base layer. I can play the file but it's just HDR10. Ehat could be ...

Re: Dolby Vision now possible through MP4 Mux.

New official documentation by Dolby states some concerning stuff for us: https://www.dolby.com/us/en/technologies/dolby-vision/dolby-vision-bitstreams-within-the-iso-base-media-file-format-v2.1.2.pdf "As Dolby Vision profile 4 is not supported for new applications by service providers, profile ...
