An AI video prompt describes the scene you want an AI video generator to create. Effective prompts give the model clear information about the subject, action, setting, visual style, and movement without making the instructions unnecessarily complicated. This guide explains how to write AI video prompts, structure your descriptions, and refine them when the results are not what you expected.
What is an AI video prompt?
An AI video prompt is a written instruction that tells a generative AI model what video you want it to create. The model interprets your description and generates footage based on the subjects, actions, environments, and visual details you provide. Writing an effective prompt is an important part of learning how to make AI videos, particularly when generating footage from text.
For example, a simple AI video prompt could be:
A cyclist riding along a coastal road at sunrise.
Adding more relevant detail gives the model additional direction:
A cyclist rides along a winding coastal road at sunrise, with the ocean on the right and warm morning light across the landscape. The camera follows smoothly from behind.
Both prompts describe the same basic idea, but the second provides clearer instructions about the environment, lighting, composition, and camera movement.
What should an AI video prompt include?
A good AI video prompt usually describes several parts of the intended scene. You will not need every element in every prompt, but considering them can help you decide what information the model needs.
Subject
Identify the main person, object, animal, product, or other subject in the scene.
Instead of:
A person in a kitchen.
You could specify:
A chef wearing a white apron in a modern restaurant kitchen.
Details such as clothing, appearance, and position can help establish how the subject should look in the generated video.
Action
Describe what the subject is doing. Video introduces movement, so the action is one of the main differences between an image prompt and a video prompt.
For example:
A chef places fresh herbs onto a finished pasta dish.
Specific actions give the model clearer direction than broad instructions such as “a chef cooking”.
Setting
Explain where the scene takes place and include environmental details that affect its appearance. This might include the location, time of day, weather, background, or surrounding objects.
For example:
A quiet city street at night, with wet pavement reflecting the warm glow of nearby shop windows after a recent rainfall.
Camera and composition
Camera instructions can help determine how viewers see the scene.
You might describe:
- A close-up, medium, or wide shot.
- A low-angle or overhead view.
- A tracking shot that follows the subject.
- A slow camera pan.
- A fixed camera position.
- A gradual zoom towards the subject.
Use camera terminology when it serves a clear purpose. Adding several conflicting camera movements can make the intended result less clear.
Lighting and visual style
Lighting and style help establish the appearance and mood of the video. You might specify soft natural light, bright studio lighting, warm sunset light, dramatic shadows, photorealistic visuals, animation, or another relevant direction.
You can also combine lighting and style instructions to create a particular atmosphere. For example, a rainy street filmed with cool blue lighting will produce a different visual impression from the same location in warm afternoon sunlight.
How to write an AI video prompt step by step
Writing an effective AI video prompt involves turning an idea into a clear instruction, testing how the model interprets it, and making adjustments based on the result. Follow these steps to develop a prompt you can use with an AI video generator.
1. Decide what the video needs to show
Before writing your prompt, identify the main purpose of the clip and what viewers should see happening.
For example, if you're creating a product video, decide whether the focus should be on the product's appearance, a particular feature, or someone using it. For a creative scene, consider the main event or moment you want to capture.
Having a clear objective helps you make decisions about what belongs in the prompt.
2. Write your first complete prompt
Turn your idea into a description that includes the essential details covered in the previous section.
For example:
A close-up shot of a ceramic coffee cup on a wooden table beside a window. A hand gently lifts the cup as morning sunlight falls across the table.
At this stage, concentrate on communicating the scene clearly. You can adjust individual details once you've seen how the model interprets your instructions.
3. Check whether the action fits the clip length
Consider whether everything you've described can happen within the available video duration. For example, a prompt that asks someone to enter a café, order a drink, sit down, and begin reading may contain too many actions for a short generation.
Choose the most important moment or divide the sequence into separate clips if the ai generator you are using is limited to producing only a few seconds of video at a time.
4. Generate a test video
Enter your AI video prompt into your chosen generator and select the available settings, such as duration, aspect ratio, and resolution. Generate an initial clip to see how the model interprets your instructions.
Pay attention to whether the main action happens as expected and whether the framing, movement, and overall appearance match your intended scene.
5. Refine the prompt based on the result
Identify the most important difference between your intended scene and the generated video. For example, if the camera moves too quickly, specify a slower movement. If the subject performs the wrong action, make the instruction more precise.
Only change one or two elements at a time so you can assess how each adjustment affects the next generation.
6. Save the prompt that produces the best result
Once you've generated a clip you're happy with, keep a copy of the prompt that worked well and the settings used. You can reuse successful descriptions, camera instructions, and stylistic details in future projects. Recording what worked also gives you a starting point when creating similar videos.
How detailed should an AI video prompt be?
An AI video prompt should contain enough detail to establish the important visual and motion requirements of the scene. Additional detail is useful when it removes ambiguity, but longer prompts are not automatically better. Prioritise information that changes what viewers will see.
For example, specifying that a character walks towards the camera gives the model clear direction about movement and composition. Simply asking for a character to walk leaves more room for interpretation, including where they move and how the action is framed.
It can also help to separate essential requirements from optional creative details. Start with the subject, action, and setting, then add camera movement, lighting, and style where needed. If a prompt produces inconsistent results, simplifying it can sometimes make the intended scene clearer.
How can you improve an AI video prompt?
Improving an AI video prompt usually involves identifying what went wrong in the generated clip and changing the instruction responsible for it. Avoid rewriting everything immediately. If most of the video works, change the part that needs improvement and generate another version.
For example:
Problem: The camera moves when you wanted a fixed shot.
Add a clear instruction such as:
Keep the camera in a fixed position throughout the shot.
Problem: The subject is performing the wrong action.
Describe the movement more precisely and remove other actions that could compete with it.
Problem: The scene looks different from the intended style.
Clarify the lighting, environment, or visual treatment without adding unrelated descriptive terms.
Problem: Too much happens during the clip.
Reduce the number of actions and concentrate on one moment. Separate scenes can be generated for the remaining actions.
This process makes prompt refinement more controlled because you can see how individual changes affect the generated result.
How do you write an image to video prompt?
An image to video prompt describes how an existing image should move or develop when it is turned into video. The source image already establishes much of the subject, composition, colours, and environment, so the prompt can focus more closely on movement.
For example, imagine you have an image of a boat on a lake. Your image to video prompt could say:
The boat moves slowly across the water as small waves form behind it. The camera gradually pans to the right.
The image provides the visual starting point, while the prompt explains what should happen during the generated clip.
An image to video prompt can describe several types of movement including:
- Subject movement, such as a person turning their head or a vehicle moving forward.
- Environmental movement, such as leaves blowing, waves moving, or clouds passing overhead.
- Camera movement, such as a slow pan, zoom, or tracking movement.
- Subtle animation, such as changes in lighting, fabric movement, or reflections.
Consider how the requested motion relates to the position of objects in the original image. For example, a close-up portrait may work well with subtle facial movement, while a wide landscape can accommodate environmental motion and camera movement.
How do you write prompts for AI video stories?
A longer story usually works better when it is planned as several individual video prompts. Each prompt can represent one shot or scene while contributing to the wider sequence. Start by outlining the story before writing the individual prompts. Identify the important characters, locations, events, and visual direction that should remain consistent.
For example, a simple three-scene sequence could be planned as:
- A character arrives at an unfamiliar location.
- The character discovers an important object.
- The character reacts to the discovery.
Each scene can then receive its own detailed AI video prompt.
You can use AI tools such as ChatGPT or Claude as a video story prompt generator to turn an initial idea into a sequence of scenes. For example, you could ask the tool to break a short story into five individual shots, each with its own action, setting, and camera direction. Review the suggested prompts before generating your videos, making sure character appearances, locations, and visual styles remain consistent throughout the sequence. Some tools even allow reverse prompting, where you provide the tool with a video and have it generate a prompt based on the content.
Which tool is capable of generating videos from textual prompts?
A text-to-video generator is capable of generating videos from textual prompts. These tools interpret written descriptions of subjects, actions, settings, camera movement, and visual styles to create new video footage.

What are common AI video prompt mistakes?
AI video prompt issues often come from unclear, conflicting, or overly ambitious instructions. Common mistakes include:
- Trying to show too much in one clip. Several locations, actions, or major changes can make the intended sequence difficult to interpret.
- Leaving the action unclear. Describing a subject without explaining what it does gives the model less direction for movement.
- Using conflicting camera instructions. Asking for several incompatible movements can make the intended composition unclear.
- Ignoring the duration. The requested action needs enough time to happen within the generated clip.
- Changing too much when refining. Rewriting the entire prompt makes it harder to identify which adjustment improved or worsened the result.
Treat the first generation as a starting point. Reviewing the output and making focused changes can help you develop a stronger prompt for the next attempt.
How to get better results from your AI video prompts
A good AI video prompt gives the model clear information about what should appear, what should happen, and how the scene should look. Start with the subject and action, then add details about the setting, camera movement, lighting, and visual style where they contribute to the result.
The first generation may not match your idea perfectly. Review the output, identify what needs to change, and adjust the relevant parts of the prompt before generating another version. Focused changes also make it easier to understand how your instructions affect the finished video.
