PapitaHD - appreciate the feedback. I'm going to grab staxrip and see what I can do. Anything I should know about what x265 settings to use when doing this?PapitaHD wrote: Sun May 24, 2020 9:15 amI've experimented a lot, re-encoding the BL layer with staxrip/x265 and 0.0.4alfa always merged it with EL without any problem. Also I have an m9702 so I can just mux the re-encoded BL and EL into full UHD BDVM structure (with tsMuxeR) and DV works. I spent hours by testing the results (re-encoded BL+EL), comparing them scene by scene to the HDR10 base layer and also to the full untouched UHD BluRay on my LG C8 Oled and I really beleive this method works perfectly. I've never noticed any difference between the files with re-encoded BL and the full UHD BluRays, but the differences were pretty significant comparing them to the untouched HDR10-base layer. I used the following movies for my tests: Aquaman, The Meg, Fantastic Beasts 2, Midway, Game of Thrones S08E03.yusesope wrote: Sun May 24, 2020 6:40 amFor this type of experiment, I recommend using the 0.0.4 alfa version of my tool.stephon1024 wrote: Sat May 23, 2020 3:57 pm Is there anyway to use handbrake to compress the base file before using your special 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 also modify EL.
No one has yet reversed the algorithm needed to generate new RPU metadata (and, in the case of FEL layers, new frames).
Imagine a guy (BL layer) with a weight of 180Kg who, after following a diet, reaches a body weight of 80Kg.
His clothes (EL layer) are now unusable but the clothing stores (the algorithm) are closed due to the quarantine.
The guy will be forced to use his old clothes.
He will always have clothes on but his style will be a little "sui generis".
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.
Thanks,
