Bink?
BINK? Gahhh...
Guys, a 5-meg WMV or Divx AVI looks just as good as your 28-meg frelling Bink file, and is easier to deal with as well.
As for the trailer itself... Eh. Some people here will give you a gold star for effort, but personally I fall in the "if you can't do something (intended for public display) well, you shouldn't do it at all" camp. A trailer that's less ambitious but does it well, will ultimately be more impressive than an ambitious trailer that doesn't technically pull it off.
IMHO, of course.

Notes for future trailer authors--
Don't pick background music that's been heard to death.
Try to make the pace of the music somewhat match the pace of the visuals.
Make sure your overlay text is actually legible.
Pick a consistent presentation style. Haphazardly mixing renders, captures, and stills is bad, mmkay?
Give some clue what the campaign is actually about. The whole "there's a new enemy and we're going to attack them with our beams and spaceships" thing doesn't really narrow it down much, y'know?
