How can I import my .AVI files into iMovie?

-I have some .AVI files that I really want to import, but iMovie won't let me. I have iMovie '11 .. is there a {FREE} converter/program I can download to let me import my movies? Thanks !Try AnyMP4 video converter for Mac , then you will find it could output one format supported by iMovie on Mac , so have a free trail first , then decide whether to buy . i think it is trustworthy.
