Thanks, Carl Eugen.
I seek a simple way to repeat a specific frame, not a way to increase fps. Specifically, I need to
repeat frame #3 in each group of 4 frames: 0 1 2 3 in, 0 1 2 3 3 out. I need it because
'shuffleframes' can't insert frames.
To reiterate: This works:
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
I seek a simpler way. Is there a simpler way?
Thanks!
