Sorry for the delayed response. I tried the 2nd option since it seemed to be the better of the two and MAN, you were not kidding how much faster it is; especially if ComSkip is disabled. Anyway, I ran it on the MP4 unprocessed as you suggested and the jittery video is gone. I ran it a second time with ComSkip enabled. It took longer (understandably) and again, no jittery video.
Thanks for looking into this!
