What i need to make one quality game trailer?

What you guys use to make a hight quality game trailer?
I have Fraps, Windows Movie Marker and Virtual Dub.

I use Fraps, Sony Vegas, Paint Shop Pro X2 and Audacity. Sometimes I use Fruity Loops as well.

Thanks a lot Oliver, I'll check it right now.

I use AVS Video Editor for Video editing.

Hey, thanks man! AVS Video Editor looks really interesting for me. I just now download.

You should really try Sony Vegas for video editing. It's a very pro tool. You can try at least the trial version, it has no limitations or restrictions, just expires after 30 days.

Ok i will download now, if you say i can save edited video in trial version this sounds fantastic, because £389.95 is too expensive for me

Yes I know it's expensive, but the trial version will do the job, no saving restrictions or anything.
