I agree with everything you said. The problem is that this wasn't part of a movie shot on a set. It was shot at a karate tournament as part of a performance, so the existing lighting in the video is what it is.
I came across this thread: http://fxhome.com/forums/viewtopic.php?t=39392
That sounds a lot like what I'm wanting to do. For example, I saw mention of a glow composite filter combined with a mask? I've added "Angelic Glow" just because it contained the word "glow" in it (IOW, for no particular reason) and I see "Composite-Glow: composite. I don't think I should be trying to adjust "Angelic Glow" to fit my needs, but at least I see some of the settings.
So I'll ask - what would you recommend?
Edit: I've changed from the blue orb to "Force Lightening" which my son likes better. I believe this might also be easier to work with.
Edit: One idea that I had for the reflection off the ground - in Commotion I could create a "shadow" - I'm wondering if I can do something similar in VLS and then add some kind of glow to that? As for getting the reflection off my son, I'm not sure what the best method would be.
