Seedance2 is an AI-powered cinematic video generator that transforms natural-language prompts or uploaded images into fully rendered 1080p video sequences. Built on temporal causal VAE and a decoupled spatiotemporal transformer architecture, the platform supports multi-shot story generation with consistent characters, realistic motion, and professional lighting. It also provides native audio sync and multi-language lip sync, multiple aspect ratios for social platforms, and fast generation times, enabling creators to produce marketing, social, film previsualization, and e-commerce videos without traditional production resources.
