Hello, You can save your movies in a lossless AVI format if you use a lossless codec such as Lagarith, found here... http://lags.leetcode.net/codec.html If your movies are in a lossless format you can edit them, add effects and transitions without any loss in image quality. When your opus is completed, you then convert it to a smaller, more portable format such as DivX, Xvid, wmv, etc. Of course, all this video stuff is a whole new world of learning. Yikes! Later Joe
