Since you are using Vegas Pro

Since you are using Vegas Pro I would recomend saving them as MPG-2 files, I've beenusing Vegas Pro since version 9 and Mpg -2 files are not compressed too much .MOV files are Mpg-4,

more compressed.. I find that I have to use verious tools in Vegas, Brightness and Contrast, Saturation Adjustment, and Sharpness, to get my videos to the level I want them.
