Seedance 2.0 Global Launch Paused, Copyright Dispute Causes ByteDance Emergency Halt

According to a report by The Information, citing sources familiar with the matter, TikTok’s parent company ByteDance originally planned to officially launch the AI video generation model Seedance 2.0 globally in mid-March. However, the plan has now been suspended due to a legal notice from Disney alleging copyright infringement.

Core Copyright Disputes: Disney, Actors’ Unions, and Multiple Parties’ Allegations

Seedance 2.0 was launched in China this February and quickly gained attention for its ability to accurately generate highly realistic video content. Tech executives like Tesla CEO Elon Musk also publicly praised its capability to produce movie-quality scenes from minimal prompts. However, its powerful generation capabilities have also triggered a series of copyright disputes:

Disney’s Cease and Desist Letter: Disney accused ByteDance of unauthorized use of its characters to train the model and of downloading pirated databases containing licensed characters from Star Wars, Marvel, and others. They issued a formal cease and desist letter.

SAG-AFTRA’s Criticism: The actors’ union stated that AI-generated videos depicting actors’ likenesses without permission threaten actors’ livelihoods. Union president Sean Astin (who played Sam in The Lord of the Rings) is among the victims; his character’s videos have been widely circulated online.

Celebrity Likeness Controversy: Fake AI videos of Brad Pitt and Tom Cruise engaged in battles have circulated online, drawing criticism for grossly ignoring consent principles.

Japanese Government Response: Japanese Minister of Economy, Nobi Onoda, stated at a press conference that videos appearing online show characters like Ultraman and Detective Conan fighting with Japan’s Prime Minister. The government emphasized it would not sit idly by and has instructed relevant departments to assess whether to invoke Japan’s AI law for action.

Chinese Industry Impact: Tim, founder of the well-known Chinese tech video creator “Yingshi Hurricane,” said he has never authorized ByteDance to use his likeness or videos, yet Seedance 2.0 can generate an almost identical image of him with high precision.

ByteDance’s Response and Future Impact

The report by The Information indicates that ByteDance has suspended the global rollout of Seedance 2.0, but the model continues to operate within China. Based on recent user feedback, the platform has begun restricting certain types of generated content—specifically, prompts that explicitly request imitations of specific real persons are increasingly likely to be rejected by the system.

From a broader industry perspective, Seedance 2.0 is not an isolated case. OpenAI’s Sora 2 and Google’s Nano Banana Pro also faced similar copyright disputes upon release. OpenAI received a cease and desist notice from Japan’s Copyright Overseas Data Association (CODA); Google also received a similar letter from Disney. Notably, Disney ultimately chose to sign a licensing agreement with OpenAI, legally licensing Disney content for Sora 2, and reached a commercial partnership by purchasing $1 billion worth of OpenAI shares. This shows that copyright disputes can often be resolved through licensing negotiations rather than legal confrontation.

Frequently Asked Questions

Why is Seedance 2.0 more prone to copyright disputes than other AI video models?

According to evaluation reports, Seedance 2.0’s core advantage lies in its highly accurate reproduction of real human movements, expressions, and voice characteristics. Its outputs are highly editable and can almost “fool the eye.” This extreme realism amplifies copyright infringement risks—compared to other models, it can more precisely replicate specific characters or individuals, triggering more legal responses from rights holders and individuals.

If general users generate copyright-involved content with Seedance 2.0, do they also face legal risks?

Yes. Japanese Minister Nobi Onoda explicitly reminded that, despite the convenience brought by AI technology, users must have sufficient awareness of copyright laws. If users knowingly generate content involving copyrighted characters or real persons without permission and share it on social media, they could face infringement liability in certain jurisdictions. Legal standards vary across regions; users are advised to understand local copyright regulations before use.

Can ByteDance resolve this dispute through licensing agreements similar to Disney and OpenAI?

Technically, yes. The precedent of Disney reaching a licensing deal with OpenAI shows that Hollywood rights holders are not universally opposed to AI collaborations but seek paid, compliant licensing models. However, ByteDance’s geopolitical background as a Chinese tech company may complicate negotiations. U.S. legislation and regulatory scrutiny of TikTok/ByteDance could also influence the willingness to reach such agreements. ByteDance’s legal strategy remains unclear, and the progress of negotiations will need to be observed.
