So, that's a phenomenon I haven't heard of before. What would cause a skew for each row? Is there a theoretical explanation? Is there a discussion thread about this anywhere?Drag wrote: ↑Thu Mar 30, 2023 12:51 pm I think I know what's happening: my palette generator now includes the hue shift that occurs on the lighter rows of the palette (the "row skew" setting, also in radians). Row skew is applied like this: hue += rowSkew * rowNum.
On default settings, the third row from the top (rowNum = 2) gets an additional hue adjustment of -0.174 (-10°), plus whatever you entered in the "hue" setting. This skew is different between revision E (-2.5°) and G (-5°), and is probably also different on PAL PPUs.
So, default settings, then set to SMPTE, and rowskew of 0. First hue 0, then hue -0.262 (15 degrees): And then like the previous comparisons, 0 degrees, thefox's capture, 15 degrees: In this configuration, the captured hue is always closer to the 15 degrees palette.
