As far as flash goes: This is very unique. I have yet to see another person (and I mean ever) implement video from a video game into their flash. But seeing as this was an intro for the site of my Quake3 Clan DeathMasters: I did my best and learned alot about capturing video, and integrating it into flash. I hope you enjoy this... if you don't play Quake3: You won't 8n)
Not bad, but....
Although using video from a game is something I don't think I've seen before, it's not really any different in implementation from someone using footage from their webcam, or from an MPEG file they found somewhere, in a Flash movie, so your idea isn't really as "unique" as you claim. Overall though, a fairly well made Flash movie, although I think it will be blammed anyway as a promotional video for a Quake clan is a bit too much of a "niche" thing to be successful on NG.
This definitely one of the only flash movies around with clips from an online game... just because it's a good idea doesn't mean I ripped it off. If anyone can disprove me then they really need to.
