Warner Bros. Slams ByteDance Over Seedance AI Clips Mimicking DC and HBO IP

Warner Bros. has sent a letter to ByteDance accusing Seedance 2.0 of enabling user-generated AI clips that infringe its IP, including Superman, Batman and Game of Thrones, and demanding that ByteDance cease training on these characters and implement guardrails. ByteDance has pledged safeguards, but Warner Bros. argues that the infringement stems from Seedance’s design rather than user behavior. The move follows broad industry criticism from the MPA and SAG-AFTRA and cease-and-desist actions from Disney and Paramount amid the rapid rise of AI-generated video content.
