How Do AI Video Generators Work?
AI video generators combine multiple technologies to automate the video production process:

- Text-to-Video (TTV): Transforms scripts into visual scenes, animations, or AI avatars.
- AI Avatars & Lip Sync: Realistic human avatars deliver messages in multiple languages and accents.
- Computer Vision: Helps position objects, add motion effects, and generate scenes.
- Generative Adversarial Networks (GANs): Used in deepfake and face swap tools for lifelike visuals.
