How to make a chorus video... with a mac?

OKAY. SO.
I am a broke kid, man.
I can't afford the fancy upgrade to Final Cut. DD:
So I was wondering if any of you knew any alternative free video editing programs that could be used on my mac?
I need to be able to make a chorus video, you see, and well... can't do that on imovie.

I also second this request. You can't do any of that fancy editing stuff with iMovie. >.>

(I think this may be better in the video editing section but whatever XD)
Uhh, After Effects trial? That's the only things that I know of apart from Final Cut and Premiere Pro that does all the snazzy things. ;;

try cinefx
tho i'm not sure if it works on macs...
