Hello, i have just received a used macbook for Christmas so im not completely sure what os i have or any of that. i also got a new insignia camcorder and i have been trying to connect it and edit the videos on imovie. The macbook recognizes the camcorder and sd card inside of it, but it is in .avi format which will not work on it. I downloaded handbrake and that seems to work for converting into .mp4 format but it takes a really long time and the macbook gets really warm and loud. im just wondering if theres an easier way to do this. Oh and also, the camcorder does not have a firewire input. Thank you.
