How to Write AI Video Prompts That Actually Work

Most bad AI video comes from bad prompts, not bad models. A video model has to fill in every gap you leave: what the subject looks like, what moves, where the camera goes, how the light falls, what happens first. Leave those blank and the model guesses — differently every run. The fix is to prompt like a director writing a shot list, not like someone wishing for a cool video.

The 7-layer formula

Every strong prompt answers seven questions, in roughly this order:

1. Shot and framing — wide establishing shot, medium shot, close-up, aerial.
2. Subject — concrete description. "A woman in her 30s with curly hair, wearing a red raincoat" beats "a woman."
3. Action — one visible movement with a strong verb. "Strides across the street," not "moves energetically."
4. Setting — where and when, with spatial detail.
5. Camera — one move, with a speed. Slow push-in, locked-off tripod, handheld tracking shot.
6. Light and look — lighting direction, palette, genre.
7. Audio — on models that generate sound, name what you hear and what you don't: dialogue in quotes, ambient sound, "no music" when you mean it.

Google's Veo 3.1 guidance covers the same ground in five parts — cinematography, subject, action, context, style and ambiance — with audio separate. Different guides slice it differently; the ingredients agree.

Five rules that fix most bad prompts

One action per clip. Most AI clips last seconds. Cramming walking, sitting, waving, and laughing into one prompt guarantees mush. One visible event per generation; stitch shots together for more.

One camera move per clip. "Zoom in while panning left and tilting down" is three conflicting instructions to a model. Pick one move and add a speed modifier: "slow dolly in."

Concrete verbs, not adjectives. "Beautiful" and "dynamic" give the model nothing to render. "Pours," "sprints," "flickers" describe something visible.

Put timing in the prompt. "For the first three seconds the mug sits still; then steam rises and a hand reaches in from frame left." Timestamp cues like [00:01] work too.

Say what you don't want. A short "No text, no logos, no watermark" line prevents common artifacts. Lead with the positive instruction, though — especially in Runway image-to-video, where official guidance favors describing the motion you want.

Text-to-video vs image-to-video: prompt differently

Text-to-video prompts must describe the whole scene — there's no starting image. Image-to-video prompts should describe only what changes: the image already defines composition, lighting, style, and subject. Repeating what's visible wastes the prompt and can reduce movement. If your start frame shows a woman in a red jacket on a beach, don't re-describe the jacket — write "she slowly turns her head toward the camera, hair drifting in the wind." Image-to-video wins whenever a specific face, product, or location must stay consistent.

Per-model notes

• Veo 3.1 is the realism and audio leader: synchronized dialogue, SFX, and ambient audio natively. Write dialogue in quotes, keep short clips to one scene, and use reference images ("Ingredients to Video") to lock characters across shots.
• Kling is strongest on smooth human motion. Its VIDEO 3.0 guidance documents 3–15 seconds per generation — one self-contained action per clip, with Multi-Shot for multiple framings.
• Runway (Gen-4/4.5) rewards clarity over length: one scene-and-motion prompt, one camera beat per generation, short proof runs before a long render. Documented duration is roughly 2–10 seconds.

Debugging

Don't rewrite the whole prompt when one thing is off. Change one element per iteration — prompt, source image, or model — so you know what fixed it. Start cheap at lower resolution or short duration. And save every prompt that works: a swipe file of proven prompts beats a blank box every time.
