I have lots of video I've taken of our band over the years and I'd like to burn DVDs to give to our members. Some of the video is from a pre-HD Sony MiniDV camera and some of it is from a new Sony HD camera that records to memory cards. I'm importing all the MiniDV stuff to .avi files but how do I go about mixing video from pre-HD .avi files with HD video from newer cameras on the same DVDs? I tried opening the HD files and one avi file from MiniDV in the same iMovie session on my Mac and while the HD video looked fine, the avi file was much smaller in the frame, both side-to-side- and top-to-bottom. I have Vegas Pro 11 on my Windows 7 laptop - will Vegas handle this better than iMovie, or was there just an added step I'd have to do in both iMovie and Vegas Pro?
