ClipPrompt Reverse Prompt Builder

Turn a video into the prompt that could have made it. The tool watches a clip, breaks it into subject, shots, camera and sound, then composes a copyable Wan 3.0-style prompt.

Reverse a video

How the live tool will work: it samples frames from your clip, reads subject, setting, motion, camera, style and sound, then writes one overall description, numbered shots with time ranges, and a continuity line — the official Wan 3.0 prompting pattern (Subject + Setting + Motion + Camera + Style + Sound).

Worked example — one clip, fully reversed

EXAMPLE — DESCRIBED CLIP, NOT A VIDEO FILE

Sample clip: “Night Market Noodles” · 12 seconds · 16:9 · 720p · night street-food stall. This preview embeds no video file; the shot list below is the exact breakdown a reverse pass produces, written out so you can see every decision the tool makes. Read the table first, then the prompt — the prompt is built directly from the table, nothing extra is invented.

A warm, cinematic night-market scene: a street noodle vendor works his stall under neon signs as steam and hungry customers fill the frame. Shot 1 (0:00–0:03): Wide establishing shot of a bustling night-market alley at night, neon signs glowing red and yellow above a noodle stall, steam rising from a large wok as the vendor tosses noodles; camera slowly dollies in; sound of sizzling oil, crowd murmur and distant traffic. Shot 2 (0:03–0:07): Medium close-up of the vendor's hands pulling fresh noodles, flour dust drifting through warm tungsten light, rhythmic chopping on a wooden board behind him; camera holds steady with a slight handheld sway; sizzle and chopping sounds dominate. Shot 3 (0:07–0:10): Close-up of a steaming bowl handed across the counter, chopsticks lifting glossy noodles as steam curls toward the lens; low camera angle, shallow depth of field; a quick slurp and the vendor's friendly call. Shot 4 (0:10–0:12): Cut to a smiling customer at a small plastic stool, neon reflections shimmering on the wet pavement, the stall's warm glow behind him; camera slowly pulls back; laughter and night-market ambience. Continuity: same vendor in a dark apron, same red-and-yellow stall signage, same warm tungsten lighting and wet-pavement reflections throughout; no change of location or time of day.

Why the prompt is written this way

How reverse-prompting works

  1. Watch. The live tool samples frames across the clip and reads the audio track, so motion and sound are observed, not guessed.
  2. Break down. Each shot gets subject, setting, motion, camera, style and sound — the same six slots the prompt formula uses.
  3. Compose. The slots are written up as one description, numbered shots with time ranges, and a continuity line, ready to paste into Wan 3.0.

What it cannot do — the honesty boundary

What the live version will add

None of that needs an account, a login or a payment in this preview — and the preview makes no network calls at all.
