Frequently Asked Questions
Longer videos = more watchtime?
Only if retention stays high. 30-min video with 20% retention = 6 min watched. 10-min video with 60% retention = 6 min watched. Same total. Shorter + retained > longer + dropped.
What about Shorts?
60s max. Shorter is better — 15-30s wins attention. Use Shorts as a funnel to long-form, not as the full medium.
