Which AI video generators mark their output, and which plan removes it

Fifteen generators publish enough to fill this table, beside one marking scheme, Google's SynthID. Eleven tie removal of the visible mark to a paid plan, and Wan uses a request parameter that defaults to off. Sora, Veo, Amazon Nova Reel and SceneMixer name a machine-readable signal. As of 2026-10-13.

Fig. 1 Filled = the vendor states something in that field; hollow = nothing published. Every cell's actual wording sits in the rows underneath. Recorded 2026-09-22.

Marking and removal, as stated on each vendor's own public pages. Each row carries its own reading date on its generator page; the most recent is 2026-09-22.

Inclusion rule. Generators whose own public pages state, in English, whether output carries a mark and what removes it. A generator that publishes no such statement is not given a row. Google (SynthID) is a marking scheme rather than a generator and has a row beside them. Order. Alphabetical by generator name.

1Two different things get called a watermark

The first is a visible mark burned into the frame, which a viewer sees and a crop can remove. The second is a signal written into the file so that software can tell the output was generated, which a viewer never sees and a re-encode may or may not survive. Vendors document these unevenly. Eleven of the rows above describe only the first kind, and most of those do it in a plan table. Three, the SynthID row among them, describe only the second kind. Two describe both.

That unevenness is the reason this table has a separate column for machine-readable marking rather than folding everything into a single yes or no. A cell saying not documented is a fact about what the vendor publishes, and it is recorded as such; it is not a claim that nothing is written into the file.

2The plan-tier pattern, and the four shapes that break it

Eleven vendors treat removal of the visible mark as something a paid plan unlocks, and they cross at different places: LTX Studio from Lite, Kling AI from Standard, Pictory and HeyGen and Synthesia at their cheapest paid plan, Pika from Pro, Luma AI from Plus, Fliki at a price its page does not print, Runway on its paid plans without naming one, D-ID one plan higher still, because its own note says the Lite plan is marked too, and SceneMixer at its paid memberships, whose terms add that the invisible layer stays on.

Four rows break the pattern in three different ways. Wan puts the decision in the request: its API takes a watermark parameter that defaults to false. Veo and Amazon Nova Reel describe a signal applied to everything they generate and publish no way to ask for it to be left out. Sora sits between them, with a visible watermark on downloads and no plan condition attached to it in the document that describes it.

For anyone assembling a series from more than one source, the practical consequence is that identical prompts on different plans, and on different surfaces of the same vendor, produce different deliverables. That is a question to settle before footage is collected rather than after.

3What each generator publishes

SynthID is recorded on its own page under implementers, because an invisible mark with no removal documented does not fit the same four fields.

The address behind every row is the vendor page that row was read from, and the reading date travels with it on that generator's own page. What a column may hold, and what not documented is allowed to mean, is set out on the protocol page; the columns themselves are on the fields index.
