About Seedance
Seedance is ByteDance's AI video generation model that creates high-quality video with synchronized audio from text, images, video, and audio inputs. Version 2.0 features a Dual-Branch Diffusion Transformer architecture that generates audio and video simultaneously — a first in the industry. It outputs native 2K resolution (2048x1080) video at 24fps with phoneme-level lip-sync in 8+ languages, supporting 4-15 second clips. Available through the Dreamina/Jimeng AI platform.
