Text to Video

Definition

Text-to-video is the process of generating moving video sequences from natural language prompts using AI models.

Purpose

The purpose is to automate video creation for entertainment, advertising, and education.

Importance

• Reduces cost of video production.
• Raises ethical and copyright concerns.
• Early-stage compared to text-to-image.
• Computationally demanding.

How It Works

1. Train on paired text-video datasets.
2. Encode prompts into embeddings.
3. Generate frame sequences using diffusion or GANs.
4. Smooth motion with temporal consistency models.
5. Render final video.

Examples (Real World)

• Runway Gen-2: generates short videos from prompts.
• Pika Labs: AI text-to-video generation startup.
• Google Imagen Video: research system for high-resolution video synthesis.
