Thanks, Mark. Pretty sure it's 1-2-3-4-4. I can't see any combing or interlacing, 4 and 5 seem completely identical to me. Dropping the 5th is all it needs except for every few minutes when a dup out of sequence appears. That's why I'm using "decimate=cycle=5" and "-r 24". I was executing pullup before and it was leaving more dups. The output from "decimate=cycle=5" looks spectacular except for those occasional duplicate lags. Even at 24 fps, they go by fast, but they're still noticeable. L.
