What is an AI video generator and which are the best ones?

What does it mean

AI video generator is a tool that can create a video based on a text input, image, or short script. What required a cameraman, actors, studio, and post-production just a few years ago, artificial intelligence can now create in a matter of minutes.

This is why AI video is becoming one of the fastest-growing areas of generative AI. Companies use it for creating advertisements, product videos, social media content, internal training, and customer communication.

What is an AI video generator and how does it turn text into an image?

An AI video generator works similarly to an AI image generator. The difference is that instead of creating a single image, it creates an entire sequence of scenes including movement, camera, lighting, and in some cases, sound.

The user enters a simple prompt, for example:

"A young man orders sneakers via mobile, modern urban style, commercial spot."

The model then creates a video that visualizes the given scene.

The latest generations of AI models can now:

• generate realistic character movement,
• simulate object physics,
• create consistent characters across scenes,
• generate sound, dialogues, and environmental noises.

AI Video Marketing: The Future of Effective Content Creation

Video is currently one of the most powerful formats in online marketing. The problem is that its production is often time-consuming and costly.

This is where AI video marketing comes into play.

Brands can:

• create dozens of creatives in hours instead of weeks,
• test multiple concepts simultaneously,
• personalize content for different audiences,
• respond to trends faster.

AI does not yet replace creativity or strategy. However, it significantly shortens the time between idea and content publication.

Main Advantages of AI Video Compared to Traditional Production

The biggest advantage of AI video is not the technology itself, but the speed.

While with traditional production you deal with:

• locations,
• equipment,
• crew,
• actors,
• post-production,

AI can create the first version of a video within minutes.

This brings:

• lower costs,
• faster idea testing,
• higher production capacity,
• easier content localization.

This is why AI video is now mainly used in marketing, e-commerce, and content creation for social networks.

Practical Use of AI Generators in E-commerce and Marketing

In e-commerce today, AI video most often helps in creating:

• product videos,
• advertising creatives,
• videos for Meta Ads and TikTok Ads,
• content videos for social networks,
• personalized campaigns,
• AI avatars for customer communication.

Especially in performance marketing, AI allows for significantly faster production of creatives and testing of new concepts.

Instead of producing three videos a month, a marketing team can create dozens of variants and optimize them based on performance.
