Anyway, digital format would be in YCbCr which uses offset binary, so either the YUV would need to be in signed integer form or the offset binary would require removing the offset before mixing and adding it in for final output. Also if you are a human you likely can define a color like red, yellow or green in RGB format easily, but even with years of working with YCbCr video, I still can't define colors I want without converting RGB to YCbCr, so not intuitive. | |
