How to make videos with AI.
A few years ago, AI video was an experiment. Today it is widely used in ads, social media and brand films. This guide explains the basic logic of making videos with AI, the main methods and the tricks for getting good results.

How are AI videos created?
AI video models work in two main ways:
- Text to video: You describe the scene in words and the model generates a short clip.
- Image to video: You generate or provide an image first, and the model animates it.
Professional work usually favors the second method. Each scene's image is created and approved first, then animated. This gives far more control over composition, color and characters.
Making an AI video step by step
- Idea and script: Write what the video says and its scenes. AI video works best with short scenes.
- Visual language: Set references for color, light, camera angle and style.
- Key frames: Generate the starting image of each scene and check consistency.
- Animation: Animate the images with a video model; generate several takes per scene and pick the best.
- Sound: Add voice-over, music and sound effects.
- Edit: Assemble the scenes, color grade, add text and logos.
How to write a good prompt
The clearer the description, the more controlled the result. A good prompt includes:
- Subject: Who or what is on screen?
- Action: What are they doing, how do they move?
- Place and time: Where, and at what time of day?
- Camera: Close-up or wide; static or moving camera?
- Style and light: Cinematic, natural, warm, cool and so on.
Splitting scenes works better than describing too much in a single shot.
The biggest challenge: consistency
The hardest part of AI video is keeping the same character, product and place from scene to scene. Character reference images, fixed style definitions and generating from key frames solve this. For videos that represent a brand, this control is what separates amateur from professional results.
Are free tools enough?
Free or low-cost tools are a good starting point for personal experiments and short social content. Brand videos bring extra needs: high resolution, commercial usage rights, product accuracy, sound and editing. At that point the team's experience matters more than the tool.
What to watch out for
- Check the commercial terms of the tools you use.
- Never use real people's faces, voices or registered trademarks without permission.
- Do not present AI content misleadingly as a real event.
- Follow platform rules on labeling AI content.
Frequently asked questions
How long can an AI video be?
Models usually generate clips of a few seconds. Longer videos are made by editing these short scenes together.
Can AI videos be used commercially?
It depends on the tool's license. Professional projects use tools that allow commercial use, and content rights are clarified at delivery.
Can AI create voice-over in other languages?
Yes. AI voice tools support many languages; for brand videos, script and voice need careful selection for natural delivery.
