video mixing software

[sanakan]

hi there,

i'm looking for some software for "mixing" videos, i.e. as in live mixing visuals for gigs, including overlay of typography, still pictures, etc. all i want to do is playing around a bit, so i don't need top-of-the-line stuff.

as you can see, i'm a complete beginner in this area, so i have no idea whatsoever (my knowledge extends to recognizing "final cut" as a video software - but i never used it), so can you help a dirt out with some hints?


platform: x86, windows/linux (no mac over here)
freeware a plus.

thanks
