dhdr10-opt optimizing HDR10+ #111

Closed SlashX closed 3 years ago

SlashX commented 3 years ago

Hello again,

I found that in x265 if you encode using metadata for HDR10+ you have another option called --dhdr10-opt. --dhdr10-opt reduces SEI overhead by only putting the HDR10+ dynamic metadata in only the IDR and frames where the values have changed. It saves a few bits and can help performance in the client's tonemapper. It is an option for optimizing HDR10+

If you can add an option for that. An example of this in screenshot. Test

Thank You!

I have a question, because I don't know if you have a forum where we can talk. I want to ask you what do you think of setting the vbv on a video for a specific level. Is it worth for the video, or if it helps with something. This question has nothing to do with the gui. Just wander if I should use it with CRF or not. Thank you.

I haven't even thought about creating a forum to be honest. I set up a quick discord server if you use that: https://discord.gg/GUBFP6f

dhdr10-opt is a good thing to add! Will be clear to add on that line as well, so good thinking.

I honestly haven't touched vbv settings myself. I don't stray far from the standard settings TBH.
