How to Write AI Video Prompts

Most AI-generated videos look flat or generic for one reason: the prompt was too vague. A structured prompt tells the model exactly what to render — subject, camera, lighting, style, duration. Here’s how to write one.

Why Plain Prompts Produce Mediocre Videos

When you write “a car driving on a road,” the AI video model has to guess everything: what car, what road, what time of day, what camera angle, what mood, how long. It fills in those blanks randomly — which is why results feel generic.

Professional videographers don’t show up on set without a shot list. A structured AI video prompt is your shot list. It removes guesswork and gives the model a clear creative brief.

The difference between a forgettable AI video and a polished one is almost always the prompt — not the model.

The Core AI Video Prompt Formula

Use this structure as your baseline. Not every element is required for every shot — but the more you include, the more consistent the output.

[Subject] + [Action/Motion] + [Camera] + [Lighting] + [Style] + [Duration] + [Aspect Ratio]

Subject

What is the main object or scene?

A black luxury watch

Action / Motion

What is moving, and how?

slowly rotating 360°

Camera

Camera angle, movement type, distance

low-angle orbit shot

Lighting

Direction, quality, color of light

high contrast rim lighting

Style

Visual aesthetic, genre, or reference

premium tech advertising

Duration

How long is the video?

8 seconds

Aspect Ratio

Widescreen, vertical, or square

16:9

Before & After: Same Idea, Different Prompt

Here’s the same creative idea written two ways. The structured version gives the model everything it needs to produce a commercial-quality result.

Without structure

“A luxury watch on a black background.”

With structure

Close-up orbit shot of a matte black luxury watch on a pure black surface, slow 360-degree rotation, high contrast rim lighting with subtle metallic reflections, shallow depth of field, clean minimal composition, premium tech advertising style — 8 seconds, 16:9.

Example prompts — actual AI-generated output may vary by model and settings.

5 Common Prompt Mistakes

These are the most frequent reasons AI videos don’t match expectations.

#1Too vague

"A cool video of a car."

Specify the car model, environment, lighting, camera angle, and mood. Vague prompts give the model too much creative freedom — results are unpredictable.

#2No camera movement

"A product on a table."

Add a camera move: "slow dolly-in", "orbit shot", "static wide". Camera movement is one of the strongest signals for video quality and professionalism.

#3No lighting direction

"Good lighting."

Name a lighting setup: "soft window light from the left", "high contrast rim lighting", "golden hour backlight". Lighting defines mood and visual quality.

#4No style reference

"Make it look nice."

Reference a visual style: "luxury commercial advertising", "documentary handheld", "editorial fashion photography". Style anchors the entire aesthetic.

#5Too many conflicting ideas

"Fast, slow, colorful, dark, dramatic, fun, serious."

Pick one clear direction. AI video models struggle with contradictions. One mood + one camera move + one lighting style = coherent output.

Quick Tips by Model

The same structured prompt works across most AI video models. Here are a few model-specific notes.

Responds well to explicit camera movement terms and style keywords. Duration and aspect ratio are well-supported parameters. In-site video generation available on PromptMotion.

Clear subject + motion + style descriptions produce consistent results. Use explicit aspect ratio and duration. Generate on Kling's own platform — PromptMotion generates the prompt.

Responds strongly to specific lighting descriptions and named camera techniques. State duration and aspect ratio explicitly. Generate through Google's official Veo channels.
