I’m trying to wrap my head around something.
I was supplied a video which is far from a clean chroma key plate, but I figured I should be able to get it going alright as foreground elements were still a fairly different color from the background.
But when I tried to set it up with Chroma Key: Advanced in Hue-Chroma-Intensity color space, even small hue and chroma delta values ( < 5%, < 1% on Intensity ) captured both. Obviously I can switch to RGB (which presented some issues with overlap in other regions, but it worked out in the end with multiple entries), so this is purely a “… what’s going on here?” thing.
If I had some idea of the color space it’s matching in, I might be able to go “oh yeah, I guess in that color space those colors are similar”, but at the moment I can’t think of a hue-oriented color space in which that would be the case.
Attached is a sample project file and sample image with two colors.
