How to Write Prompts for AI Video Generation
Video prompts are not just longer image prompts. Because the model has to keep every frame consistent with the last, complexity works against you — the more elements a scene has, the more chances something flickers, morphs, or drifts. The single most useful habit is to describe one subject doing one thing.
A workable structure: subject, action, setting, camera, mood. For example, "a ceramic coffee cup on a wooden table, steam rising slowly, morning light from a window, slow push-in, calm" gives the model a clear subject, one motion (steam), a defined setting and light, one camera move, and a tone — without competing details.
Leave out what you will add later. On-screen text, logos, and precise brand colours are better handled as overlays in your editor; asking the model for them usually produces garbled lettering and wastes a generation.
Specify the camera deliberately. "Static shot", "slow orbit", "handheld", and "push-in" all produce meaningfully different results, and picking one keeps the model from inventing erratic movement. If you want the subject still and only the camera moving, say so.
Expect to iterate. Generate two or three variations of the same prompt, keep the best, and adjust one thing at a time — changing the whole prompt between attempts makes it hard to learn what actually helped.
What does a bad prompt look like?
A bad prompt is a list of adjectives with no subject, or a whole plot in one paragraph: 'epic cinematic futuristic beautiful amazing city of dreams'. The model has nothing concrete to draw, so it improvises, and the result is inconsistent between generations.
What does a good prompt look like?
'A red paper boat floating on a calm pond at dawn, mist on the water, slow push-in, soft light.' It has one subject, one motion, a setting, a camera move and a mood. You can read it in a breath, and every word changes the image.
How do you improve a prompt?
Change one thing at a time and keep notes. If the camera feels wrong, change only the camera word. If the lighting is flat, change only the light. After a handful of attempts you will have a prompt template that you can reuse for every video in a series.
Frequently asked questions
How long should a video prompt be?
One or two sentences. More detail usually means more places for the model to be inconsistent.
Should I put text in the prompt?
No. Add on-screen text as captions in the editor so spelling and fonts are correct.
Why do my videos look different each time?
Models are probabilistic. Generate two or three variations and keep the best; keep the prompt stable so you can compare.
