Good reference, Dave, thanks. However, I was curious as to the numbers in parentheses in the classification headers Best, Better, Good. They were 16, 8, and 4. What is the significance?
Kevin:
Good question. According to Robert Reinhardt of flashSUPPORT.com, when you use web video codecs such as Sorenson Spark and On2 VP6, the best frame dimensions are where the width and height of the frame are divisible by 16. If you can't have both divisible by 16, then the lesser options are divisible by 8, then 4.
