Here's a screen shot of one of the clips, chosen at random.
As a follow-up test, I took another short clip and applied the .5x and then the .3x speed adjustment. Perhaps predictably, the .5x was fairly smooth, while the .3x showed definite evidence of jerkiness. Nowhere nearly as bad, of course, as the .1x of the YouTube clip. I rendered both in the wmv format, using the 2nd HD setting (720p).
Looking forward to hearing your thoughts -- and, I hope, solution. Thanks.
