What is the problem in the attached photo? Why is the output of Merge1 desaturated?
It’s foreground input, Merge_FG_01, outputs two merged RGBA images as one pre-multiplied image (as a Merge node does). It’s alpha channel is 1.0 for the foreground.
It’s background input, Magenta, is a Background node set to a solid magenta color.
Merge1’s Channels and Settings tabs use default settings.
The same thing happens when I input media (H.264 video) as a background in Merge1.
Just for grins, because this looks a bit like an alpha multiplication issue, I tried setting Merge1 to Subtractive and even tried Alpha Multiply and Alpha Divide nodes before Merge1 on both inputs: didn’t help.
What am I doing wrong?
