The technique is chapter bar under the frame: the viewer sees the structure of the video and where they are in it. How it works: a labelled chapter bar with a moving playhead under the video frame, one label per beat. It is right for: breakdowns, launch films, how-it-was-made posts. On the measured launch film the bar shows eight beats in 40 seconds, so viewers can see that the answer gets about 7 seconds and the channels about 11. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing."
