They differ in their greediness and verbosity on the status line.

I've searched the docs one-by-one. I seek a simpler way to repeat a frame.
This:
split[1][2],[1]setpts=(N+floor(N/4))/FR/TB[3],[2]select=eq(mod(n\,4)\,3),setpts=(N*5+4)/FR/TB[4],[3][4]interleave
works, but perhaps there's an easier way that I'm just not seeing.
Suggestions are welcome. Thanks!
