With nothing to copy, the model decides everything: the subject, the set, the lens behaviour, the light. That makes a text-to-video prompt do two jobs at once — it picks what appears and it picks how the thing is shot. A prompt that only names a subject has quietly handed the second job back to the model, which is why three words return a different film every time you press go.
The trade is control. You cannot guarantee that a face, a product label or a brand colour survives from one generation to the next, because there is no reference for it to survive from. Iteration is the tool instead: hold the seed, change one clause, and compare the two takes side by side.
It wins on establishing shots, abstract b-roll and anything where a version of the idea is good enough. It loses the moment the clip has to match something that already exists — a real product, a real face, a shot you generated yesterday. Those are jobs for image-to-video and reference-to-video.
In practice
- The prompt carries subject, action, camera behaviour, light and the state the shot ends in.
- Clip length is chosen up front from a fixed set of options, not trimmed afterwards.
- The same prompt at a different seed is a different take, not a correction.

The mistake to avoid
Reading a weak result as a model failure. Far more often the prompt named a subject and nothing about the shot, so framing, motion and lighting were all left to chance.

Image-to-video
Image-to-video animates a still you supply: the picture becomes the opening frame, and the prompt describes only what happens next.
Prompt
A prompt is the written instruction a generative model reads to decide what to make — the one input almost every model requires.
Seed
A seed is the number that decides the random starting noise for a generation, so the same seed with the same settings reproduces the same output.
Reference-to-video
Reference-to-video builds a clip around subjects supplied as separate reference images, rather than starting from one fixed opening frame.
Duration
Duration is how long a generated clip runs, chosen before generation from whatever lengths the model supports rather than trimmed afterwards.
