How to Write Better AI Video Prompts
A practical step-by-step framework for turning a simple idea into a clear, cinematic and coherent AI video prompt.
Writing a good AI video prompt means translating the scene in your head into visible instructions a generative model can work with. Unlike a still-image prompt, a video prompt also needs to communicate what changes over time: how the subject moves, what happens in the environment and, when relevant, how the camera moves.
The strongest prompts are not necessarily the longest. They prioritize the details that define the shot and avoid instructions that compete with one another. The framework below can be adapted to different AI video tools and different visual styles.
1. Start With a Clear Subject
First establish what the viewer should notice. Your subject can be a person, animal, object, vehicle, product or even a landscape feature.
Instead of beginning with a long list of style words, establish the subject in concrete visual language:
A small orange cat wearing a blue apron...
If a characteristic needs to remain consistent across multiple scenes, make it specific enough to repeat later.
2. Give the Subject a Visible Action
Video depends on change. Describe an action that can be seen on screen rather than relying only on an abstract emotion.
Less specific
“A nervous chef in a kitchen.”
More visual
“A chef grips a wooden spoon, glances toward the oven and slowly steps backward.”
The second version translates the emotional idea into physical behavior that can appear in the frames.
3. Establish the Environment
The environment gives context to the action. Describe the location and only the details that matter to the scene: weather, time of day, important objects, background activity or atmosphere.
A small orange cat wearing a blue apron kneads dough on a wooden counter in a warm cottage kitchen while rain runs down the window behind it.
Avoid introducing environmental details that contradict one another unless the contrast is intentional.
4. Choose the Shot Size
Shot size determines how much of the subject and environment the viewer sees.
- Close-up: emphasizes a face, object or small detail.
- Medium shot: balances the subject with some surrounding context.
- Wide shot: emphasizes environment, scale and spatial relationships.
- Extreme wide shot: makes landscape or location the dominant visual element.
Choose the framing according to the story information that matters most in that moment.
5. Add Camera Movement Only When It Helps
Camera movement should support the action rather than exist only because cinematic terminology sounds impressive. For a simple shot, one clear primary movement is often enough.
- Push-in: moves closer and can increase focus on a subject or detail.
- Pull-back: reveals more of the environment.
- Tracking: follows a moving subject.
- Pan: rotates horizontally to follow or reveal something.
- Orbit: moves around a subject.
- Locked camera: keeps the viewpoint stable while action occurs within the frame.
Medium close-up. The camera slowly pushes toward the cat as it kneads the dough.
6. Use Lens Language Carefully
Lens terminology can help communicate a photographic intention, but it should not replace clear descriptions of framing and perspective. If a particular focal-length look matters to your concept, you can include it as supporting information.
For example, a longer-lens portrait look can suggest stronger subject separation, while a wider perspective can emphasize space. If you are unsure, a clear phrase such as “close-up with shallow depth of field” is often easier to understand and edit than adding technical numbers without a reason.
7. Describe Lighting as Something Visible
Lighting changes mood, depth, color and subject readability. Useful descriptions connect the light to a source or visual effect:
- soft morning light entering through a window
- warm practical lamps inside a dark room
- golden sunset backlight around the subject
- cold moonlight across a wet street
- neon signs reflecting in puddles
Try to keep the lighting direction compatible with the environment and time of day.
8. Separate Three Types of Motion
When a scene feels complicated, divide motion into three categories:
Subject Motion
Walking, turning, lifting, falling, running, blinking or interacting with an object.
Environment Motion
Rain falling, curtains moving, smoke rising, waves breaking or dust drifting.
Camera Motion
Tracking, panning, pushing in, pulling back, orbiting or remaining locked.
You do not need all three in every shot. This mental model simply helps prevent motion instructions from becoming a confusing list.
9. A Reusable AI Video Prompt Formula
Using that structure, a simple idea can become:
A small orange cat wearing a blue apron kneads dough on a wooden counter in a warm cottage kitchen while rain runs down the window. Medium close-up, slow camera push-in. Warm practical lights illuminate the cat and countertop, subtle steam rises in the background, natural paw movement, detailed cinematic 3D animation.
The formula is a guide, not a requirement. Remove any category that does not contribute to the shot.
10. Build Multi-Scene Prompts One Shot at a Time
If your video contains several story beats, avoid forcing the entire sequence into one overloaded prompt. Break it into individual scenes with one primary event in each.
Scene 1 — Establish
The orange cat in a blue apron stands at the wooden kitchen counter and pours flour into a ceramic bowl. Medium shot, gentle push-in, warm cottage lighting.
Scene 2 — Continue the action
The same orange cat wearing the same blue apron kneads the dough in the same cottage kitchen. Close-up on the paws and bowl, locked camera, soft steam in the background.
Scene 3 — Payoff
The same orange cat in the blue apron proudly places a freshly baked loaf on the wooden counter. Medium close-up, subtle pull-back revealing the warm kitchen, golden light and gentle steam.
Each scene advances the story while repeating the identity and environment anchors that matter.
11. How to Improve Character Continuity
AI video continuity can be difficult because each generation may introduce variation. Prompt writing alone cannot guarantee perfect consistency, but clear repeated anchors give the model less ambiguity.
Identify what must not change: fur or hair color, clothing, age, key accessories, vehicle design, room layout, major props and dominant style. Repeat those details in later scene prompts when they remain relevant.

12. Avoid Conflicting Instructions
A prompt becomes harder to interpret when it asks for incompatible visual directions at the same time. Examples include demanding a completely locked camera while also requesting a dramatic tracking shot, or combining several unrelated art styles without a clear dominant look.
When two instructions compete, decide which one is essential to the shot and remove or rewrite the other.
13. Don't Confuse Detail With Quality
Adding dozens of adjectives does not automatically improve a video. Every extra instruction competes for attention. Prioritize information that changes what is visible: the subject, action, environment, framing, movement, lighting and essential style.
A concise prompt with a clear event can be more useful than a paragraph full of generic words such as “masterpiece,” “amazing,” “epic” and “ultra cinematic.”
14. Refine One Variable at a Time
After generating the first clip, compare it with your intended shot. Identify the largest mismatch and revise that part first.
- If the action is wrong, clarify the action.
- If the camera is wrong, simplify or change the camera instruction.
- If the environment moves incorrectly, specify the relevant environmental motion.
- If the visual mood is wrong, adjust lighting or style.
- Generate again and compare before changing another major variable.
This makes iteration more systematic and helps you learn which wording influences your chosen model.
15. Three Complete AI Video Prompt Examples
Cinematic nature scene
A lone hiker in a dark red jacket walks along a narrow mountain ridge above a sea of clouds at sunrise. Wide shot. The camera slowly tracks behind the hiker while low clouds drift through the valley. Warm rim light outlines the jacket, realistic wind movement, cinematic natural landscape.
Cozy ASMR-style scene
Close-up of two hands slowly pouring hot chocolate into a handmade ceramic mug on a wooden table. Steam rises naturally as soft rain appears out of focus behind the window. Locked camera, shallow depth of field, warm amber lamp light, realistic textures, calm cozy atmosphere.
Product-style scene
A silver perfume bottle stands on a polished black stone surface. The camera performs a slow controlled orbit as a soft strip of light travels across the glass and metal cap. Dark minimal background, crisp reflections, premium commercial-film aesthetic.

Frequently Asked Questions
What should an AI video prompt include?
A useful prompt usually identifies the subject, visible action and environment, then adds important framing, camera, lighting or style information when those details affect the intended shot.
How long should an AI video prompt be?
There is no universal ideal length. Write enough to communicate the important visual and motion information, but remove unnecessary or conflicting instructions.
How do I keep a character consistent across AI video scenes?
Repeat defining identity anchors such as appearance, clothing, accessories, props, environment and dominant visual style when those elements should remain unchanged.
Should I specify camera movement?
Yes when camera movement is important to the shot. Choose a clear movement that supports the action rather than adding camera terminology without a visual purpose.
Can the same prompt work in every AI video generator?
A clear visual prompt can be a useful starting point across multiple systems, but models can interpret the same language differently. Review the output and adapt the prompt to the tool and model you are using.
