What each generator documents about marking its output

Veo's free column holds a signal, not a mark

Veo's documentation says videos it creates are watermarked using SynthID. Nothing is published about a mark on the frame, so the value in this column is an invisible signal rather than something a viewer sees. As of 2026-09-22.

Two cells in one row, both about documentationThe documentation states that every video carries a named invisible signal and says nothing whatever about a mark on the frame. One cell therefore holds a specific claim and the other holds not documented, and the register does not convert the silence into a claim that the frame is clean.What the frame carriesWhat the file carriesDocumentedNothing at allA named invisible signal on every videoRecorded asNot documentedThe scheme, plus a verification platformWhat a viewer getsNo published answerNothing to see by designWhat software getsNo published answerSomething to check, with a named readerBoth halves are readings of the documentation, not of files

Inclusion rule. One row for the value, one for the sentence or absence behind it, one for the method. Nothing here is drawn from output, support replies or coverage by anyone else. Order. Fixed order: the value, then its evidence, then the method.

Inclusion rule. Generators whose pages describe what output carries without naming a plan, so the value in this column is a default rather than a condition of payment. Order. Alphabetical by generator name.

1A column about visibility, filled by something invisible

The obvious reading of this column is what will a viewer see, and on twelve rows that is what it holds. Here the only documented mark is one no viewer can see. The cell says so plainly rather than recording a blank, because a blank would suggest the vendor had said nothing, and it has said something quite specific.

The visible-mark cell on this generator is the one that records not documented. Nothing in the documentation describes anything on the frame, and the register does not conclude from silence that the frame is clean. Both halves of the row are statements about the documentation, and the pair is more informative than either.

2Under Limitations, which is a grammar choice

The sentence appears under a heading called Limitations, alongside the things a developer cannot change. That placement carries meaning: the mark is being presented as a property of the output rather than as a feature of a plan, in the same register a rate limit is written in.

Nothing in the documentation offers a parameter, a flag or a tier that alters it. So the control cell records not documented and the paid cell records the same mark with no removal documented. A vendor that marks everything and publishes no route off is a shape that only appears among the developer-documented entries here.

3A named scheme is what makes the cell useful

Naming SynthID does more than describe a behaviour. It hands a reader a thing to look up, and the organisation behind the scheme publishes its scope, the moment the signal is written, the transformations it is designed to survive and two routes for checking a file. The documentation also names the verification platform directly.

That is why the scheme and this generator are kept as separate entries rather than merged. A scheme can be described in detail while every product using it stays quiet, and most of this register is products staying quiet. Here the product speaks, briefly, and points somewhere a reader can go next.
