What makes a good video prompt

Short clips reward prompts that describe one clear action.

Subject

a red fox

One main subject keeps the motion clean.

Action

leaps over a frozen stream

Use one verb the viewer can see. Six seconds is one shot.

Setting

snowy forest at dawn

Place and time of day set the look.

Camera

slow tracking shot

Name the move: dolly in, pan, handheld, aerial.

Light & mood

soft golden light

Light changes the mood more than adjectives.

Style

cinematic, shallow depth of field

Add a style word or two, not a list.

Ideas to try

Product shots

A sneaker rotating on a pedestal, studio light, slow orbit.

Nature

Waves crashing on black rocks at sunset, aerial shot.

Characters

A robot barista pouring latte art in a cozy cafe.

City

Neon street in the rain at night, camera moving forward.

Food

Syrup pouring over a stack of pancakes, close-up, slow motion.

Storyboards

Block out a scene before shooting or animating it.

Tips

One shot per prompt

Six seconds fits one action. Split longer ideas into several clips.

Describe motion

Say what moves and how fast. Static descriptions give static videos.

Write prompts faster

Use the AI Video Prompt Generator to turn an idea into a shot-by-shot prompt.

Match the platform

Pick the aspect ratio before generating; cropping later loses detail.

Avoid text on screen

Video models still struggle with readable words.

Scale through the API

Batch generate variations through the API once a prompt works.
