WebSep 7, 2024 · Normally, x264 encodes all three colour planes (luma, U (chroma), V (chroma)) at the same quantizer. This value will be added to the quantizers for the U and V planes. This allows you to bias x264 in favour of brightness (luma) by setting positive values (chroma fields will have higher quantizers), or in favour of colour (chroma). WebA parser to parse H.26 sps/pps.
