Change yuv individual pixel colour
Is there a function/plugin that can change pixel with luma 17 to 16.
I got the hex numbers and loaded up an mp4 file with a hex software then replace 17 with 16. When i checked with ColorYUV(analyze=true), both original and new file, it didn't work. Apparently it changed another colour but i don't know which. tara |

Interesting. With ColorBarsHD() as the source, I get 850fps with Expr and 1200 with mt_lut. I don't have an AVX2 capable processor. But yes, it does not make a difference once the encoder gets involved
