Flagship Seedance 2.5 Pro AI Video Generator
ByteDance's flagship generative video architecture with up to 30s single-pass sequences, 12 multi-reference inputs, native acoustic soundscapes, and cinema 1080p output.
What Is Seedance 2.0?
Seedance 2.0 is ByteDance's next-generation multimodal AI video generation model designed to create cinematic, photorealistic 1080p video with native, synchronized audio in a single pass.
Unlike conventional AI video generators (such as Runway Gen-3 or OpenAI Sora) that produce silent video clips requiring separate sound engineering, Seedance 2.0 simultaneously synthesizes character dialogue, acoustic physics, environment foley, and soundtrack. Powered by unified spatial-temporal attention, it supports text-to-video, image animation, and up to 12 multi-reference inputs for rock-solid character and style consistency.
Native Acoustic Physics
Step-synchronized audio and video generation without latency or dubbing artifacts.
12-Shot Consistency
Retain character identity, wardrobe, and face geometry across camera cuts and lighting angles.
30-60s Fast Turnaround
High-throughput inference cluster delivers finished 1080p clips under one minute.
