Name it, prove it, keep it short

Write a script outline, beat by beat, with the seconds per beat, for a short video about [your product], for [your audience]. Use the name it, prove it, keep it short pattern: the viewer leaves with one named idea and has seen its proof. Measured on one account's top 20: median length 26 seconds, 4.4 visual changes per 10 seconds, from no narration at all to 105 spoken words. How it works: one idea per beat with its name on screen, the proof shown as a number or a result, under about 90 spoken words, 18 to 45 seconds. Plain spoken language, no hashtags, no emoji. Tell me which one you would post first and why, in one line.
