AI Video Generation

Definition

AI video generation creates videos from text prompts, images, or other inputs using generative models.

Key Technologies: - Diffusion models adapted for video - Temporal consistency techniques - Motion prediction - Frame interpolation

Leading Models: - Sora (OpenAI) - most advanced - Runway Gen-2/Gen-3 - Pika Labs - Stable Video Diffusion - Kling (Kuaishou)

Capabilities: - Text-to-video generation - Image-to-video animation - Video extension - Style transfer

Current Limitations: - Short duration (seconds to minutes) - Temporal consistency issues - Physics violations - High compute cost

OpenAI's text-to-video model that generates realistic videos from text prompts.

AI models that generate data by learning to reverse a gradual noising process.

AI systems that can understand and generate multiple types of content like text, images, audio, and video.
