I think you're also overlooking the fact of the sheer file size of RED video footage. It would take them hours or days to upload that video to their servers just to view it to see if it were worth using, and on top of that, no where in it's verbiage does it give them license to use or view your copyrighted work in any way.

If you find your work on their site or in their promos, they are in violation of copyright laws and are liable. No judge would stand behind such weak boilerplate to allow RED to steal artist's work with impunity.

I hate to say it, but you're far too worried about this. I understand the misgivings but the reality of the situation doesn't match your concern over the matter, or to put it another way, you're making mountains out of molehills.
