Thanks all!

I'm at a bit of an impasse right now, as the brightness boosting technique of using "screen" on several layers and this newest technique seem to be mutually exclusive. Meaning that I can remove the blue, but I can't fix the brightness without putting an unaltered video stream above the rest of the video streams, thus reintroducing the blue that I've worked so hard to remove. I'm sure there's an answer, other than rendering the video and then re-importing it to fix the brightness, which might be a mess.

Anyway, I'm glad people are interested in the work, and hopefully something will be useful for other projects at some point.

Onward!
