Freeware: FFmepg,Handbrake and Freemake are all good selection, completely free and no other cost. Handbrake has both windows and Mac version. all great for converting avi to mp4 and other foramts, and rip dvds for all users. have a try. and some rechargeable software such as iVideotool Video converter may much better for converting and compress videos
