For Mac users, iMovie is a free and powerful software for you editing video on Mac OS including iMovie 08, iMovie 09, iMovie HD. It can help Mac and iPhone 4 users crop video, trim clips, add transition, add titles etc. Because iMovie has too many functions for editing files, I will only share with you some common functions about how to edit video with iMovie!

Take the newest version iMovie 09 for example.

iMovie has strength editing function, but it also has some weakness. iMovie 09 only support limited formats such as MOV, DV, HDV, MPEG-2, MPEG-4, AVCHD, H.264. If you want to import your MOD files from your Canon, Panasonic, JVC, TOD files from JVC or other unsupported formats to iMovie, what will you do?
