The Motion Picture Association and ByteDance announced on 17 August what the MPA calls a first-of-its-kind agreement: a Memorandum of Understanding setting out a shared framework for maintaining guardrails on generative AI video and image models. It covers Seedance and Seedream — versions 2.0 and 2.5, and 5.0 Lite and 5.0 Pro respectively — as deployed across TikTok, the TikTok USDS joint venture, CapCut and Dreamina.
What the common framing gets wrong
It is being reported as a copyright deal, a pact, and in places a truce — language that in this industry means a licensing agreement with money attached, of the kind labels have struck with music-generation companies. This is not that. A memorandum of understanding is a statement of intent. The MPA's own announcement discloses no financial terms, grants no licence to any studio catalogue, and contains no release of claims: no studio has waived anything, and no member company's legal position has changed. What ByteDance has agreed to is a framework for guardrails going forward.
The unanswered question is the training data
The announcement is silent on inputs. It describes protections and guardrails on the models as deployed; it does not state whether ByteDance trained Seedance or Seedream on studio libraries, nor commit to anything about future training data. That is the question at the centre of every generative-AI copyright case now in court, and this document does not address it.
How the parties got here
In February 2026 the MPA sent ByteDance a cease-and-desist after the release of Seedance 2.0, and ByteDance suspended that model's global launch. The MOU is the negotiated end of that episode. Charles Rivkin, the MPA's chairman and chief executive, framed it in terms of principle rather than terms: "Today's agreement illustrates our belief that copyright is a cornerstone of the film and television industry." ByteDance general counsel John Rogovin said the company "respects the intellectual property rights that underpin creative industries around the world."
Why the studios wanted a document at all
ByteDance is a Chinese developer whose model teams sit largely beyond the practical reach of US courts, which makes injunctions and damages awards weak instruments. A negotiated framework is what is available when litigation is not. It is also useful: the studios can now point at it in their live cases against US model developers as the reasonable alternative — an argument that works whether or not the MOU obliges ByteDance to do anything.
