Seedance 2.0 hit with Hollywood copyright backlash; API suspended indefinitely
Previous post said the API would open in late February, but the situation has changed. Seedance 2.0 has ignited a wave of Hollywood copyright complaints: the API is suspended indefinitely, and major features have been heavily restricted.
What Happened
On February 10, Seedance 2.0 launched in China under the name 即梦 (Jimeng). Immediately, users began mass‑generating AI videos featuring Hollywood film characters and actor likenesses and flooding them onto social networks.
The spark was a two‑line prompt by Irish film director Ruairi Robinson that generated a Tom Cruise vs. Brad Pitt fight scene. It exceeded one million views on X. After that came posts using Hollywood IP one after another: an Avengers: Endgame remake, an alternate ending to Game of Thrones, a Stranger Things reboot, and more.
Hollywood’s Response
Things moved quickly in Hollywood. From February 13, major studios sent a wave of cease‑and‑desist letters over about a week.
| Date | Organization | Action |
|---|---|---|
| 2/13 | Disney | Sent a cease‑and‑desist; called infringement of Marvel, Star Wars, and Pixar IP a “virtual heist.” |
| 2/13 | MPA (Motion Picture Association) | CEO Charles Rivkin demanded that infringement stop immediately. |
| 2/13 | SAG‑AFTRA (actors’ union) | Condemned it as “blatant infringement,” citing unauthorized use of members’ voices and likenesses. |
| 2/14 | Paramount / Skydance | Sent a cease‑and‑desist; alleged infringement of South Park, Star Trek, and The Godfather. |
| 2/17 | Netflix | Sent a cease‑and‑desist over Stranger Things and Bridgerton; warned of immediate litigation and demanded action within three days — the hardest line. |
| 2/17 | Warner Bros. | Sent a cease‑and‑desist; criticized unauthorized use of DC heroes as “an intentional design choice.” |
| 2/20 | CAA (talent agency) | Issued a statement calling it “a blatant disregard for creators’ rights.” |
| 2/21 | MPA | Sent a formal cease‑and‑desist letter to ByteDance — the first such letter to a generative‑AI company. |
What most angers the MPA is that ByteDance used copyrighted audiovisual works at scale, without permission, as training data. They call it “systemic infringement rather than inadvertence” and “a feature, not a bug.”
Features Halted or Restricted
ByteDance limited or disabled features within days of release.
| Feature | Status |
|---|---|
| References to real people in images/videos | Suspended |
| Photo → voice generation (produce a person’s voice from a single photo) | Suspended |
| Face and voice cloning | Disabled across the board |
| Global API | Suspended indefinitely |
| Generation of copyrighted characters | Filtering reinforced |
In the China‑domestic versions (Jimeng, Doubao), liveness verification (recording your face to prove you are you) is now required if you want to use your own face. You cannot use someone else’s face.
This doesn’t mean everything that worked in 1.5 Pro is gone, but IP/likeness content filtering has been introduced to 1.5 Pro as well.
ByteDance’s Response
On February 16, the company issued statements to AP and the BBC:
We respect intellectual property rights and are taking measures to strengthen existing safeguards to prevent users from the unauthorized use of intellectual property and likenesses.
BytePlus (the overseas cloud service) said it would “formally reopen the relevant services as soon as possible after rapid improvements to copyright‑protection mechanisms and deepfake defenses,” with the specific timing to be announced later.
The MPA rejected this as an insufficient, generic statement.
Impact on Those Waiting for the API
All the ComfyUI integration items summarized in the previous post are on hold for now. The API had been scheduled to open on February 24, but it has been postponed indefinitely. No restart date is set.
Even if it does resume, expect changes like these:
- Major limits on the person‑reference feature: The workflow of using Universal Reference to generate videos that reference arbitrary people will likely be restricted due to copyright and likeness filtering, trending toward only allowing your own face (after identity verification).
- Stronger content filtering: Pre‑generation blocking will be tightened for copyrighted characters, celebrity likenesses, violent content, and more.
- Spillover to the 1.5 Pro API: Similar filtering is being applied not only to 2.0 but also to the 1.5 Pro API.
Copyright Risks for Video‑Generation AI
This isn’t just about Seedance. Seedance stood out because the quality is so high that “it can make video that really looks like the real thing.”
Other video‑generation models — Sora 2, Veo 3.1, Kling 2.x, and others — share the same issue of having copyrighted content in their training data. Seedance happened to be the first one targeted, but it wouldn’t be surprising for the same pressure to be applied to other services.
The MPA’s cease‑and‑desist is the first case directed at a generative‑AI company and sets a heavy precedent. With Hollywood now moving in earnest, the way video‑generation AI services are offered overall may be affected.
