How we checked
We ran the same two 10-second 9:16 clips (a person talking against a wall, and a beach) through each one ourselves: videoexpander.ai on 2026-11-09, Magic Hour on 2026-11-09, Runway on 2026-11-09. Runway's numbers come from its pricing page and help center that day. AI Video Expand's row comes from its own prices. Prices and free tries change often: if one here is out of date, email support@aivideoexpand.com.
