In front of the camera
I've finished recording my professional videos.
The more experience I get, the more I realize that what matters is never doing a retake. The first take is always the best.
The idea takes shape in my head in real time. The micro-expressions that come with finding the words are the best cues for the viewer. Even the clumsy recoveries after a mistake create a connection.
When you redo it, it's often clearer, more organized, more complete... but it doesn't speak to people as much.
UPDATE: that evening, it took me 5 takes to record a personal video that was better that way – and it's doing really well. So there you go.
