That’s great news. Thanks in advance from my side for all the effort!

Some remarks about banding: While I’m not too familiar as of now when it comes to video encodings, in the audio domain, it is always (!) advisable to use dithering in order to transform distortion (in the video domain that corresponds to the infamous ugly banding) into an equally distributed error, resulting in way more pleasant (and often enough not even noticeable) noise.

With video, that may raise the data rate requirements in conjunction with lossy codecs - which would also be my guess why dither is apparently rarely used (besides pure ignorance I suppose) as technically, no bit depth has banding as a direct consequence, but only determines the noise floor under ideal circumstances. Even with 10 bit or whatever bit depth, dither should be applied in theory, but I suppose it is much less of a problem with > 8 bit / color, just as it is neglectable when dealing with 24 bit PCM audio.

So in case you encoding software actually supports (random) dither like the renderer “madVR” does, maybe you can enable that for the next release.
