Specs that pass quality checks.

• ▸9:16 vertical, 1080×1920 minimum, burned-in captions (80% watch muted)
• ▸45–75 seconds sweet spot for educational faceless niches
• ▸New visual every 2–4 seconds — static slides die in Reels
• ▸Hook text on screen in frame 1, not second 3

Hook templates that repeat safely.

Rotate five hook archetypes: the paradox ("Everyone thinks X — they're wrong"), the number ("3 signs…"), the story cold open ("In 2008, one bank…"), the question ("Why does Facebook pay creators less than YouTube?"), and the contrast ("Rich people do X. Poor people do Y."). Never use the same archetype twice in a row.
