Seedance 2.0

Seedance 2.0 is ByteDance's AI video generation model that went viral in February 2026. Built on a Dual-Branch Diffusion Transformer architecture, it generates video and audio simultaneously — including lip-synced dialogue, sound effects, and ambient audio. It outputs native 2K (2048x1080) video in 5-15 second clips and accepts multimodal inputs (text, image, audio, video) with up to 12 reference files for character consistency. Integrated into Dreamina (CapCut's AI platform), it offers quality rivaling Sora 2 at a fraction of the price. The model sparked a major Hollywood copyright controversy after users generated viral clips using copyrighted characters.
