What is AI Video Generation?
AI video generation uses deep learning models to create video clips from text prompts, images, or existing footage. As of 2026, leading models include Seedance 2.0, Sora 2, Kling 3.0, and Runway Gen-4, producing clips from 4 seconds to 2+ minutes in up to 4K resolution.
How AI Video Generation Works
Key concepts behind AI-powered video creation.
Diffusion Models
Most AI video generators use diffusion models that start from visual noise and progressively denoise into coherent video frames guided by your text or image input.
Text-to-Video (T2V)
Type a description and the AI generates a matching video clip. Models like Sora 2 produce up to 20-second clips from a single prompt.
Image-to-Video (I2V)
Upload a still image and AI animates it into video. Seedance 2.0 Director Mode accepts up to 12 reference images for consistent multi-shot output.
Video-to-Video (V2V)
Feed existing footage and AI restyles, upscales, or transforms it while preserving motion. Runway Gen-4 leads in style transfer controls.
Temporal Consistency
The biggest challenge in AI video: keeping subjects, lighting, and physics consistent across frames. Face-lock and motion prediction address this.
Pricing Models
Most tools offer free tiers (5-30 generations/month) with paid plans from $8-$30/month. Open-source options like Wan 2.6 can be self-hosted for free.
