Synthesia's input rule is a consent requirement about a person
A custom avatar requires that the person is over the applicable legal age and has given free, informed consent for their voice or likeness to be used. The input restriction on this row is a duty owed to a human being. As of 2026-09-22.

Inclusion rule. One vendor, one column. A cell earns a page when the vendor publishes something specific there, or when its silence is unusual beside the vendors read with it. Order. Fixed order: the wording, then its address, then the method, then the gap.
1The condition sits on the route out of the restriction
The custom avatar is what lifts the limits on paid promotion elsewhere in this vendor's row. Consent is the price of that route, which makes this cell the other side of the crossing point rather than a separate rule bolted on.
Read together the two cells describe a coherent design: a stock presenter comes with limits and no obligations, and a real person comes with obligations and no limits.
2Free and informed are words with content
Free points at pressure, which is the live question when the person is an employee. Informed points at scope, because somebody agreeing to appear in internal training may not have agreed to appear in a campaign two years later.
Legal age is the third element and the easiest to check. The register records all three as published; how a particular arrangement satisfies them is exactly the question a page cannot answer.
3Why an input rule outranks a licence line in practice
A licence problem is a dispute with a supplier who wants to keep the account. A consent problem is a dispute with a person whose face is in a video, and it does not settle by upgrading a plan.
That is the argument for keeping this column at all, even though thirteen rows in it are silent. Four vendors here say something about what may be supplied, and what they say is the part that survives a change of tooling.

4From the making side
Alongside the terms behind “Synthesia, input rule”, SceneMixer's guides describe the work itself this way:
The music runs across the end card and comes to an end with the film.

The final cut ends on an end card: your main image plus four lines — Brand, Product name, Tagline, Call to action. The first two are read from your photo and your brief; the tagline and call to action are written with the script.

5Where this reading came from
The cell above was taken from the video licensing page published at synthesia.io, as that page stood on 2026-09-22. The remaining three cells of the same vendor row sit on Synthesia; the column itself is described on input restriction. This is a filing decision and not legal advice.
