Upload a video and HookScan measures its first 8 seconds: when the first word is spoken, when the picture first changes, cuts, movement, on-screen text, faces, loudness and silences. Each check is PASS or FIX with the change in seconds. You also get two re-cut videos: trimmed_open.mp4 with the silent start and long pauses removed, and cold_open.mp4 that opens on your strongest line. No retention guesses, only measured numbers. A 10-minute 1080p file took about 3 minutes in our test.

Paste one paragraph about your planned Short or Reel and get 10 cold-open lines, each with on-screen text, a first-frame note and the beat where the video keeps the promise. Checked for length, sound-off reading and a promise kept by a beat you described.

Diagnose why the first 6 seconds of your short-form video loses viewers — get a second-by-second evidence timeline, up to 3 named findings, 3 structurally different replacement hooks, and a timecoded edit table you can cut today.
