A condition on the uploads, and a consent line for real people
HeyGen's grant holds as long as uploaded material avoids copyright violations and character inputs stay clean. SceneMixer accepts a photograph as a character reference on a paid plan with the rights to it, and prohibits deepfakes of real people without documented consent. As of 2026-09-22.
| The question | HeyGen | SceneMixer |
|---|---|---|
| Kind of rule | A condition on the licence | A permission with two conditions |
| What the customer must hold | Clean uploads | The rights to the photo; consent for a real person |
| What is still possible | Any upload that qualifies | A real person's likeness, with consent |
| Where it is written | Inside the grant | A help guide, and the terms |
Inclusion rule. Two vendors whose published answers in one column point in different directions, or sit far enough apart that a reader choosing between them would decide differently. Order. The vendor named first in the heading is the one whose wording is quoted first.
1Both keep the choice with the customer
Making clean inputs the condition on a grant leaves the customer free to supply anything that qualifies, and leaves the judgement about qualification with them. The other row does the same with a sharper edge: a photograph needs the rights to it, and a real person's likeness needs that person's documented consent.
2What each approach asks a production to keep
The conditional grant asks for a record of what went into each clip, and prompt text counts as an input on that row. The consent rule asks for a document from the person whose face is used, which is the record a brand's legal review will want anyway.
3A guide and a term do not age the same way
One rule sits inside a published grant; the photo rule on the other row sits in a help guide and the consent rule in the terms. The register records each with the date it was read, which keeps a product description and a contractual term in the same column without pretending they are the same kind of promise.

4Both documents
The first column comes from the export help article at heygen.com, read 2026-09-22; the second from the compliance guide at scenemixer.com, read 2026-09-12. Each vendor’s full row is on HeyGen and SceneMixer, and the column being compared is described on input restriction. A comparison of wording is not legal advice.
