What is the Image Quality index (step 9), and what should I set it to?
The Image Quality index is like the quality index of Jpeg images with 100 being the sharpest (best) and 0 being the smoothest (worst). This setting applies to individual frames, as if they were individual images. For quality asf clips with moderately high bitrates like our clips, we generally want to use an index between 90 and 100.
