I am working on a large High School Track DVD that has many photo's and video clips in it. I have broken up the video into chapters of which are about 5 minutes each in length. In a particular chapter, I may have up to 40-50 mini clips or photo's. I will then save each chapter as a single file in which I will import that single file into my final product. I'm wondering what the best format to save these chapters is. I am currently saving as an AVI file, but I have noticed the quality of the video is degraded somewhat in the final DVD. The photo's display fine, only the video seems degraded. ????
