What is the AI Video Generator?
An AI video generator is a software tool that uses artificial intelligence technologies—like machine learning, NLP, and computer vision—to automatically create videos. These tools can turn text, images, scripts, or other forms of input into animated or realistic-looking video content. AI video generators can be used for YouTube videos, product explainers, e-learning courses, social media reels, and even professional presentations.
Popular platforms such as Pictory, Synthesia, Lumen5, InVideo, and Runway have made it possible for users to create studio-quality videos in just minutes using pre-built templates and AI voiceovers.

How AI Video Generator Works
AI video generators typically follow a simple workflow:
-
Input Phase: The user provides a script, text, or topic.
-
AI Interpretation: The AI analyzes the input using NLP and determines context, tone, and relevant visuals.
-
Visual Matching: Based on the script, the AI selects stock footage, animations, or generates new visuals using AI rendering engines.
-
Voiceover Addition: The AI adds voiceovers using text-to-speech (TTS) systems in various languages and accents.
-
Editing & Rendering: The platform assembles the elements, allowing the user to preview, edit, and export the final video.
