The input restriction column, and the exposure that starts before the render
This column records what a vendor says may not be supplied as an input. Four of the seventeen vendors fill it, three of them about a real person's likeness and one about copyright in uploaded material, and the rest do not raise the subject. As of 2026-09-12.
| Vendor | What the column holds | Where such a rule normally sits |
|---|---|---|
| HeyGen | Uploaded material must avoid copyright violations, and character inputs must stay clean | Stated in the export article, as a condition on the grant |
| Higgsfield | An image of another person may not be used without that person's permission | Stated in a help centre answer |
| SceneMixer | A photograph on a paid plan, with the rights to it; documented consent for a real person | Stated in a compliance guide |
| Synthesia | A custom avatar needs the person's free, informed consent and confirmation of legal age | Stated on the licensing page, as a consent condition |

Inclusion rule. The same vendors carried everywhere on this register, read on the pages they publish about rights. A restriction written only inside an acceptable use policy is out of scope here. Order. Rows with a published restriction first and the blank rows after them, then alphabetically by vendor inside each group.
1Most of the likeness exposure arrives on the way in
A reference photograph of a recognisable person carries that person's rights into the job before a single frame is generated, and nothing a vendor permits on the output side reaches back to fix it. Publicity and personality rights sit outside the contract entirely, which is why this column exists as its own axis rather than as a footnote to the licence.
It is also the axis a brand controls. The plan a team is on is chosen once; what gets dragged into a reference slot is chosen on every job, usually by whoever is fastest, and usually without the plan card open in another tab.
2Three ways of writing the same likeness rule
Higgsfield forbids uploading or using an image of another person without that person's permission, which puts the obligation on whoever drags the file in. Synthesia asks, for a custom avatar, that the person is over the applicable legal age and has given free, informed consent for their voice or likeness to be used. SceneMixer accepts a photograph as a character reference on a paid plan if the user holds the rights, and its terms prohibit deepfakes of real people without documented consent.
Permission, consent with an age condition, and rights plus documented consent are three ways of writing one rule, and all three ask a production to hold a document. A team that works from client headshots should have that document before the first render, because none of them can be satisfied after the fact.
3One row is about copyright rather than a face
HeyGen's condition sits inside its grant: the permission holds as long as the inputs align with standard guidelines, which are described as avoiding copyright violations in uploaded materials and keeping character inputs free of sensitive or offensive language. It is the only row here where the input rule and the output licence are one sentence.
That construction makes the permission contingent on something neither side can evidence cleanly. A brand relying on it is relying on its own clearance of the inputs, which is where the obligation would have sat anyway; what the wording adds is that a failure there reaches the licence as well as the rights holder.
4A photo slot on a paid plan, with a consent line
One row opens the reference slot to photographs only on a paid plan and only with the rights, and draws a separate line for real people: documented consent. That makes the vendor's rule legible to a reviewer in two sentences, which is rarer in this column than it should be.
The row records the rule in the vendor's own words and does not translate it into a promise about output the vendor did not make.
5Blank here means unread, not permitted
Thirteen rows are blank, and input rules do exist elsewhere in this market. They live in acceptable use policies, which are separate documents with their own definitions and their own amendment history, and which this register does not read for the same reason it does not read terms of service: the test for what goes in a cell is a sentence on a page the vendor sells from.
So a blank cell here should be read as an instruction to go and look, not as a permission to supply anything. Anyone working from photographs of real people is in territory that no line on a pricing page settles, and a column that implied otherwise would be doing more harm than an empty one does.

Every row restates a reading already held on commercial use and on the vendor page it came from, checked 2026-09-12. What a sentence has to do before it counts as a licence statement is set out on the reading page. This column is a filing decision, not legal advice. The other columns: Free tier, Commercial use from.
