The best model for brand work is the least legally settled

Seedance 2.5 leads the benchmarks, and it is the model your client's legal team will ask about by name. Both of those are true, and a studio that tells you only the first half is selling you something. What follows is practitioner notes, not legal advice.

ByteDance released Seedance 2.5 in July 2026. On the independent Artificial Analysis board it leads image-to-video overall, and it leads the sub-categories that decide whether a brand film survives a client review: photorealism, camera control, human anatomy, retail and ecommerce, and cartoon/anime. Seedance 2.0 still holds the top position for audio sync and for lighting and materials. The benchmark summary.

What the spec sheet actually buys

Thirty-second clips. Native 4K at 10-bit, generated at that resolution rather than upscaled into it, which is the difference between footage that holds a grade and footage that falls apart in one. Up to fifty multimodal references in a single prompt, and references are not limited to stills: audio, 3D white models and style references all count. Audio is generated in the same latent space as the picture instead of being made separately and synced afterwards. There is a 3D white-box previz pass, so a shot can be blocked before anyone pays to render it. The specs in full.

It is also expensive. $34.12 per minute of output on the Artificial Analysis board, against $4.80 for MiniMax H3. Roughly seven times. On a thirty-second hero shot that gap is noise next to the cost of the people in the room. On a volume social build it decides the model on its own.

February

The objections were raised against Seedance 2.0, and they arrived inside a fortnight.

• User clips appearing to feature One Piece, Dragon Ball, Arcane and Ip Man characters.
• A shot that nearly duplicated one from the 2025 film F1.
• A viral clip of Brad Pitt and Tom Cruise fighting.
• The actor Scott Adkins seeing his own likeness in output.

SAG-AFTRA said Seedance 2.0 "disregards law, ethics, industry standards and basic principles of consent." MPA chairman Charles Rivkin said there was unauthorised use of US copyrighted works "on a massive scale" and that ByteDance "should immediately cease its infringing activity." Disney reportedly sent a cease-and-desist letter on 13 February 2026, and Paramount Skydance on 15 February, with Paramount alleging "blatant infringement" of Star Trek, South Park and Dora. ByteDance responded on 16 February: "we have heard the concerns… taking steps to strengthen current safeguards." Senators Blackburn and Welch asked the company to shut Seedance down on 16 March. The global rollout was paused in March and resumed with guardrails. NBC News on the dispute; CineD, 14 February 2026.

Two things that are not established

No lawsuit over Seedance could be verified. What exists is cease-and-desist letters and public statements. A letter from a studio's counsel is a demand, not a finding, and the distinction matters a great deal when the decision in front of you is whether to use a tool rather than how to defend one.

“The indemnity clause tells you whether you are allowed to sell it.”

The most-circulated piece of evidence is also shaky. Newsweek questioned whether the Pitt and Cruise clip was fully AI-generated at all. Their report. That clip did more than anything else to set the temperature of the story, and it may not have been what everyone took it for. Overstating this is as useless to a client as ignoring it, so we state it both ways and let them weigh it.

The part that reaches the contract

Seedance, through BytePlus, offers no indemnification. Earlier BytePlus terms placed responsibility for infringement on the customer. If a rights holder ever makes a claim, the model vendor is not standing in front of you, and your client's master services agreement very likely says you are standing in front of them.

That is the whole decision, and it is a procurement decision rather than a creative one. The benchmark tells you what the model can do. The indemnity clause tells you whether you are allowed to sell it. Those two answers come from different documents and almost never get read in the same meeting, which is why a model gets approved in a creative review and then dies in legal three weeks before air.

The only case with a docket

Disney and Universal sued Midjourney on 11 June 2025. NPR's report on the filing. It is still live in 2026 and has moved into a discovery fight over the studios' own use of AI. There is no final ruling. So nobody can tell you where the line falls on training data or on output similarity, because no court has drawn it yet. Anyone offering a settled answer is guessing, in either direction. Treat confident reassurance from a vendor the same way you would treat confident doom from a competitor.

How we run it

• Ask the indemnity question before the model question. If the client's MSA requires the supplier to carry IP risk, Seedance is out, unless the studio is willing to carry that risk itself, in writing, on its own balance sheet. Price that honestly or decline the brief.
• Name the model and version per shot in the production spec and again in the delivery manifest. "AI-generated" is not a record. "Seedance 2.5, image-to-video, references owned" is a record.
• No existing characters, no recognisable talent, no reference frames pulled from released films or commercials. Every reference that goes in is owned or licensed, and the chain is written down before the shoot, not reconstructed after a complaint.
• Design the thing you want. Most of the February examples came from prompts that asked for known IP and got it. A model that will reproduce a character on request will also leave it alone when you describe something original instead.
• Keep the white-box previz pass in the project file. It is useful as previz and it doubles as evidence of human direction, which matters for copyright reasons covered in the next piece.
• When a client's legal team wants provenance over quality, use a model built for provenance and accept the trade. Say the trade out loud. A client who chose it knowingly will defend the choice; one who was not told will not.

The question worth putting to a client's counsel at kickoff is narrow enough to answer in one line: does our agreement require model-level indemnity for generative output, and if so, which models has your legal team already accepted? If there is an answer, the model list is theirs rather than yours, and the creative conversation starts from something real. If there is no answer, you have found the thing that would have stopped the job in week six, in week one.
