ByteDance and the MPA sign a copyright truce, and nobody outside the room can read it

ByteDance and the Motion Picture Association have signed a memorandum of understanding that the MPA, in a press release, calls a shared framework for protecting its members against copyright infringement ^[1]. Neither side has spelled out what the safeguards actually are ^[2], which means the people shipping on CapCut and Dreamina now work under a rulebook they cannot read.

The scope is broad. According to the MPA, the memorandum applies to all ByteDance AI models, including those used on TikTok, the TikTok USDS Joint Venture, CapCut and Dreamina ^[7], four named product surfaces ^[23]. The models at the centre of the dispute are Seedance, ByteDance's video generator, and Seedream, its image counterpart, which sit behind the AI features in TikTok, CapCut and Dreamina ^[8]. The MPA's members include Disney, Paramount and Warner Bros. Discovery ^[9]. The trade body said the agreement "represents significant cooperation between the two organizations" ^[3] and that Seedream 5.0 Pro and Seedance 2.5 reflect "continued advances in IP protections" ^[10].

That is a warm read of a fight that opened in February, when the MPA sent a cease-and-desist letter after Seedance 2.0 appeared, calling the tool an engine of "systemic infringement" ^[4]. Individual studios including Disney, Netflix, Warner Bros, Paramount and Sony had already sent their own warnings ^[11]; Disney pointed to viral clips featuring Marvel and Star Wars characters, and Japan opened a separate inquiry into anime look-alikes ^[12]. ByteDance then pledged to strengthen its safeguards around unauthorised use of intellectual property and likeness, and reportedly suspended Seedance 2.0's global rollout ^[13]. MPA chief executive and chair Charles Rivkin has since described "constructive engagement" and said the company implemented "meaningful guardrails" ^[14]. The version numbers are the tell: the model that drew the letter was 2.0, the model now cited as evidence of progress is 2.5, half a release later ^[16].

The MPA's complaint had two prongs, one about outputs, that Seedance would generate recognisable copyrighted characters and celebrity likenesses on demand, and one about inputs, that the model was trained on studio content without permission ^[15]. The pact answers the first far more than the second ^[17]. Output filters are the tractable half: making a model decline to draw Iron Man is an engineering task, and it settles nothing about whether the film libraries taught it what Iron Man looks like ^[18]. The studios also are not obviously being paid, because a voluntary pact is not a licensing deal ^[5].

For operators, the practical problem is asymmetry of information. The specifics are undisclosed, which makes the guardrails impossible to assess from outside and easy to loosen quietly, and enforcement across TikTok, CapCut and Dreamina at those apps' scale is a formidable undertaking ^[6]. A prompt or template that clears review this month may fail next month, and there is no published standard to appeal to.

Context for how much leverage this represents: Hollywood has watched OpenAI pull its Sora app amid legal and reputational heat and seen the Oscars ban AI actors and AI-written scripts ^[19], while studios remain in court against Midjourney on infringement claims ^[20]. Litigating ByteDance, headquartered beyond easy reach of US courts, was an uncertain prospect, so the MPA negotiated guardrails it can point to now ^[21].

Watch whether any of the terms are published, whether the MPA carries this template to rival generators ^[22], and whether the truce hardens into the licensing regime the studios actually want ^[24].
