When a video can be guided by images, clips and audio from several sources, the creative brief also becomes a record of permissions, responsibilities and approvals.
AI video agreements are often written as if the only input were a text prompt. That assumption is already outdated. A modern project may begin with a product photograph from the client, a motion clip licensed by an agency, an audio reference supplied by a freelancer and a style board assembled from several internal sources.
The creative team sees a useful reference pack. A lawyer or project manager sees a chain of rights that needs to remain intact from upload to publication.
This issue becomes visible in a multimodal system such as Seedance 2.0, which accepts text, image, audio and video references and allows creators to describe how those materials should shape motion, atmosphere and scene structure. The technology can make direction more precise. It also makes vague contracts harder to defend.
Reference Files Are Not Just Inspiration
A mood board used in a private meeting is different from a file uploaded to a generation platform. Once an asset becomes a model input, the team should know who owns it, who supplied it and whether the planned use falls within the permission granted.
That question cannot be answered by file possession alone. A client may own a finished advertisement without owning every song, photograph or performance used to create it. An agency may have a licence limited to one campaign, territory or channel. A freelancer may provide a reference for internal review but not for derivative production.
The safest approach is to treat every uploaded asset as a production input with its own rights record. The record does not need to be elaborate. It should identify the asset, source, owner, licence or consent basis, permitted use and any expiry or territorial limit.
The Brief Should Define the Role of Each Asset
Rights management becomes easier when creative direction is specific. If an image is used only to preserve a product’s shape, record that purpose. If a video guides camera movement but not costume, performers or setting, say so. If audio establishes pacing, distinguish that role from copying a composition or voice.
The platform supports text, image, audio and video references in one generation. That flexibility makes role assignment part of both prompting and governance. A prompt that explains each reference is easier to reproduce, review and connect to the relevant permission.
This also reduces a common dispute after delivery: the claim that a particular source influenced the output more than the client expected. A clear reference manifest cannot eliminate every disagreement, but it gives the team a shared record of intent.
Client Contracts Need More Than an Output Clause
Many creative agreements concentrate on ownership of the finished video. Reference-based generation introduces several earlier questions:
- Who is responsible for confirming rights in client-supplied inputs?
- May the agency upload those inputs to a third-party platform?
- Can the materials be used only for this project or for future variations?
- Who approves the prompt, references and generated draft?
- What happens when the output contains an inaccurate logo, person, product detail or claim?
- How long should input files, prompts and generated versions be retained?
These points belong in the statement of work or production terms, not in an email written after a problem occurs. The agreement should allocate responsibilities without pretending the tool can guarantee factual or legal suitability.
Platform Rules and Project Permissions Are Different
Seedance 2.0 states that real human faces, including selfies, portraits and celebrities, are not supported because of upstream restrictions. Copyrighted, violent and NSFW content is also rejected. These platform rules provide an important boundary, but compliance with them does not automatically settle every contractual issue.
A file may pass a technical upload check and still fall outside a client’s licence. An illustrated character may not be a real face but can still belong to another rights holder. An original audio recording may include a performer whose consent does not cover synthetic adaptation.
Project approval therefore needs two separate checks: whether the platform permits the input and whether the organisation has the right to use it for the intended purpose.
