AI video prompt library

Every prompt here produced a video we published on YouTube, TikTok and Instagram. No made-up examples: you get the output, the exact prompt, what made it work, and the Cast settings that get you closest.

Phone-POV livestream

The character films herself on her own phone: one continuous take, eye level, talking straight into the lens.

Dance to a song

A choreographed dance locked to a song that goes into the model as an audio reference.

Trend format

A known TikTok trend structure (walk-up, break-away, regroup) performed by your characters.

Tutorial / how-to

A borrowed creator format: ingredient, step, close-up, reveal, with a twist at the end.

Explainer

Many short clips of one character, cut to a voice-over that teaches something.

The pattern behind all of them

  1. Paint the first frame, then animate it. An image prompt fixes the face, outfit, set and light; the video prompt only has to describe motion and sound.
  2. Make the camera a thing in the room. “The phone propped on the table, eye level, the only viewpoint, no cuts” is what produces a believable one-take livestream.
  3. Timestamp every beat. 0-4s, 4-9s, 9-14s… with exact quoted dialogue. Seedance follows a timeline far better than a paragraph.
  4. End on a turn. A gag, a reveal or a change of heart in the last five seconds.

The longer write-up, including what gets blocked and what it costs, is in the Seedance prompting field guide.
