In fact, what I'm describing now is technically called YcBcR. That's luma and the color blue and color red, but people often use these terms and others interchangeably without any clear idea about the difference. Actually, YUV uses a specific scale, a graph if you prefer, with U and V as readings on that scale. YcBcR is quite a lot to say, so we use the term YUV as a more general reference to an approach that puts luma in one channel and colors into other channels. In video editing systems, it's usually the luma, that's measurable light, the amount of blue and the amount of red, or some other two color channel combination that represents the color in the pixel. The important distinction for me is that one system just measures color, that's RGB, and the other system separately measures the luma, but when I'm speaking about these things, what's…
