Color Curves puzzle
I’ve been using Final Cut since the Dark Ages but I’m a perpetual newbie so perhaps I am missing something basic…
If I have a clip and I add a Color Curve effect and leave the RGB settings at 100% then there is no change in the image. Of course.
However, if I make three stacked layers of the same video and set one to all red (100, 0, 0), the next up to all green (0,100,0) and the top layer to all blue (0,0,100) the image does not look the same. In this case, there is a magenta shift.
Opacity for each layer is set to 100 for the bottom layer, 50, and then 33.33. Color blending is “normal.” There are no other effects or adjustments. Tried Fuji Flog2 footage and standard iPhone footage–both were the same.
What I am trying to get to is to have the three layers, after adjusting so each is its own separate color, to result in an image that matches the single-layer version. It seems to me, from a logical point of view, that the three-layer version (R + G + B) would be the same as the one-layer version (RGB)–am I missing something?
