New Halide blog post on post-processing for chroma as it is relevant to compression efficiency: https://halide.cx/blog/chroma-handling

Seems like you can get a roughly 2% efficiency improvement with 4:2:0 decoder output just with smarter post-processing for chroma. Pretty neat!

Metrics don't just measure encoder performance; decoding matters too, and even after decoding, not all post-processing is created equal.

@gianni Thanks for the great article! Quite some time ago, I tried my hand at a chroma upscaling filter:

@barrbrain wow, definitely going to look into this, thanks! Very cool!!
