I had some old 8mm films converted to digital. I gave the company a hard drive. They returned it to me with Canopus Type 2 avi files. Four in total each over 15GB in size. I want to get certain clips from each of these files as there is no order to them and make DVD's for my siblings. I am new to the Mac, have iMovie and QTPro with some add on I downloaded. Nothing seems to work to convert to .mov ,,.dv HELP!!!
