hey guys i am film student and am making a 2 hour documentary for one of my projects. I was going through a lot of the exporting codecs and i found a lot of them to be really blurry after exporting and then burning. I need your help as soon as possible on what good codec to use during exporting and what is the best codec to use to fit the documentary on a 4.7gb dvd or would it be best to put on a dual layer. Please get back to me guys i would appreciate your help and hope to get a good grade on my project... thanks guys
