Encoding Discussion Megathread (ffmpeg, Handbrake, AV1, etc...)

[grunt]

the complications are unreal., this script alone I use to fix DolbyVision files on for my appleTV is crazy big

I didnt write that, but I like your thinking, just making something that converts everything to a "modern and efficient" way would be unreal hard to do lol

I should maybe start my own GitHub and start putting things on there, but again, laziness and time. Movie/tv collection is a hobby for me and so is scripting to make it work the way I want. Like you, I do it when I have moments to spare (usually when im slacking at work, working from home helps lol). Dog and a newborn are time killers, barely have time to game, which is my fave hobby lol

Dont have kids... lol

I'm dealing with my first 4K HDR video.  How do I convert it from Dolby Vision 7.6 to the more compatible DV 8.X.  My phone (Pixel 6a) will try to direct play it, but the video is blank.

Does something like this exist on Linux?  dovi_tool I think I read about somewhere.

that above script uses dovi_tool

I am sure since it works on OSX it wouldn't be too difficult to convert it to a working *unix bash script. That script actually originated from a windows script found here

If you want a complete mind fuck of a discussion of how complicated Dolby Vision is, go through the above.

The reason I use the DV7 to DV8 script is because some DV8 (hybrid files) can come in two profiles (CMv2.9 and CMv4.0) and the Apple TV (via infuse) only supports CMv4.0 properly on the latest Apple TV hardware (gen 3). This script will fix that issue as well as convert profile 7 to 8. Nothing other than blu ray players should support profile 7 (some android boxes out there do, and I think the latest shield pro, but could be wrong)

Funny thing is though, Apple TV 4K gen 2 and 1 can play most if not all CMv2.9 files, while gen 3 can't. SOOOOO annoying, as I have 2 gen 2s in my house, and 1 gen 3, but unfortunately the main viewing TV has the gen 3 Apple TV.
