A LUT utility for making some OBS 64x64x64 color correction lookup tables (encoded as 512x512 PNG files).

There's nothing too fancy here, it's just a bunch of vanilla JS modules to make it all happen. Starting at index.js you should be able to read along just fine.

Right now the builder allows for some saturation-for-brightness compensation (using hsv.s += hsv.v/f, where f is the value from the slider), as well as some (normalized) compression, to combat the whole "this video stream encodes pure black's as 16 rather than 0". Or general black/white-point raising/lowering.

That's what github pages are fo, so fire it up here: https://pomax.github.io/LUT-builder/index.html

You know where to find the issue tracker =)
