Seedance 2.0
Seedance 2.0 jointly generates audio and video from text, image, audio and video references (9+3+3 per prompt), and Hollywood objected to it.
Unified audio-video architecture with 15-second clips and director-style control of performance, lighting and camera. It topped Artificial Analysis (1,213 Elo, tied by Alibaba's HappyHorse in April). Viral clips of copyrighted characters triggered studio cease-and-desists within days and a delayed API rollout.
