I had some home movie footage that I saved as a 75MB AVI file back in the mid/late 90s. Today, I used Windows Live MovieMaker to make a two and a half minute clip from the original AVI. It has resulted in a WMV file that is just over 100 MB, ie. 25% bigger than the entire original clip. I was expecting it to be around 10MB given the original about 15mins.
Is this related to my choice of video format or have I done something wrong?
