Drop-off diagnosis
The exact frame where brain engagement drops — and why
Instagram's algorithm surfaces Reels with high initial watch rate — the percentage of people who keep watching past the first 3 seconds. Brain data shows that Reels hooks triggering the amygdala (emotion) retain 60% more viewers than information-only hooks. Supports .mp4 and .mov, 9:16 vertical format optimized for Reels analysis.
