ByteDance adds watermarking and IP guardrails to Seedance 2.0 ahead of global rollout
Six weeks ago, a video of Tom Cruise fighting Brad Pitt on a rooftop went viral. It was, of course, not real. It was generated by Seedance 2.0, ByteDance’s AI video model, and it set off a firestorm that drew cease-and-desist letters from six major Hollywood studios, a formal denunciation from the Motion Picture Association, and a pointed rebuke from SAG-AFTRA over the unauthorised use of its members’ likenesses. Rhett Reese, the screenwriter behind the Deadpool films, watched the clip and offered a blunt assessment of the technology’s implications for his profession.
TL;DR
- ByteDance is relaunching its AI video tool, Seedance 2.0, with new safeguards after a previous version caused controversy.
- New safeguards include blocking the generation of videos from images or videos containing real faces and preventing the unauthorized generation of copyrighted characters.
- All output will feature visible watermarks and embedded C2PA Content Credentials, along with an advanced invisible watermarking technology.
- The initial rollout will be to paid users in Brazil, Indonesia, Malaysia, Mexico, the Philippines, Thailand, and Vietnam, with the US and India notably excluded.
- The relaunch occurs as OpenAI shuts down its own AI video tool, Sora, and ahead of the EU AI Act's transparency requirements taking effect in 2026.
- Testing suggests that creative prompting may still bypass some filters, creating "likeness-adjacent" characters.
- ByteDance's vertical integration across AI model creation, editing platform, and distribution channel (TikTok) positions it uniquely but raises questions about rigorous enforcement of IP protections.
