Well yes, I do know a little math.

BUT, it does not work.
Setting a timestamp_align of 6 seconds results in a start delay of just 6 seconds…
I’ll continue testing, but for the concept:

What I need is to compensate for the time it takes FFmpeg to start.
So, what I really need is:
	’start capture if time > x seconds since epoch’ (or something like that.)

Otherwise, what’s the use? What am I missing here?
