Often it probably takes 20-30 minutes to make a good, to the point, 60 second video. Maybe it's just me. Part of it is when I watch myself on video I will often think of a couple things that could have made the video visual/content better (or more simplified); possibly another way to explain; sometimes the baby cries/screams. Sometimes the camera woman's foot is in the corner or the video... the potentials are limitless.
Typically after the 2nd redo my camera woman will say, "Final take!" Most of the fails/blooper are immediately deleted. Below is a video of some of the mistakes, fails, bloopers that didn't get deleted. There are others somewhere. I remember falling falling-ish doing a single leg TRX jump... maybe it's best that clip is lost :)
