Incorporate HDR10 stream?

[asarian]

I've been using DGHDRtoSDR to deal with HDR(10) content. I'd love to have a filter that actually incorporates the HDR steam, though. Does that exist yet? (If so, couldn't find it).

most VS filters have the capability to handle int16 or even fp32 content, I don't think you need anything special to deal with int10

What does this mean?

I must be doing it wrong then

x264 [info]: profile High 4:4:4 Predictive, level 4.0, 4:2:0, 8-bit

It seems to output in 8-bit (for a lossless, intermediate encoding).

I invoke x264 like this:

VSPipe f:\jobs\%1.vpy - --y4m | x264 - --demuxer y4m --opencl --frames %_frames% --sar 1:1 --qp 0 --output "%2:\video\%1.h64"

Like a Dolby Vision layer.

the encoding precision of your video encoder has nothing to do with the format of your vaporsynth output, an 8-bit version of x264 will output an 8-bit stream even if you give it a 16-bit input. the correct way to write an intermediate file is simply thru vspipe

vspipe xxx.vpy xxx.bin -p

then you read xxx.bin with rawsource

That's a mighty fine tip!

As for x264, aren't they all 10-bit now? I took mine from videolan (05-May-2021).

Not when encoded for use with broadcast television, 2K Blu-ray discs and media streaming services... h.264 is encoded at 8-bit!

And playback support for 10-bit h.264 encodes is pretty limited for use with hardware (SoC) media players and TV's...

Then what is the point of processing UHD video, when everything gets converted to 8-bit?!

4K UHD disc content along with 4K UHD broadcast and 4K UHD media streaming services is encoded using h.265 (HEVC) at 10-bits!
