[Craig Seeman] "NTSC color information is carried on a subcarrier (3.58MHz is memory serves) which could drift. I don't think that was ever the case with PAL (maybe PAL-M used subcarrier too 4.43MHz if memory serves although my memory of analog is fading)."
PAl avoid the hue deviations by shifting 180 degrees the chroma phase every line.
If there is a hue error that produces a wrong color in one line, will produce the complementary color in the next line. Our eyes will integrate both colors and we will see the correct one.
But this is not my question.
I understand well the Hue issue in analog NTSC and the situations that can produce it, but I don't understand when a Hue shift can come from on an all-digital-tapeless workflow.
I don't understand why he talks about hue shift when he is cutting files right from a camera.
Where the hue shift may come from?
