What each generator documents about marking its output

Moving mark: the attribute that defeats a crop

A moving mark changes position over the duration of a clip. Because no single region contains it for the whole shot, reframing cannot be relied on to exclude it, which is the first thing anybody tries. As of 2026-09-22.

Why motion changes what a reframe can achieveA badge fixed in one region can be excluded by a single crop, because the region it occupies is the same for the whole clip. A mark that travels has no such region, so a crop that excludes it at one moment includes it at another.A fixed badgeOccupies thesame region forthe whole clip.One cropExcludedA singlereframe removesit, at the costof composition.CompareA travellingmarkOccupiesdifferentregions secondby second.No single cropStill presentA frame thatexcludes it atone momentincludes it atanother.

Inclusion rule. Words this site uses in a narrow sense, where the ordinary sense would lead a reader to misread a cell. No vendor statement appears on this page. Order. Fixed order: what the word names, what it excludes, then where it is used here.

1One adjective, and what it rules out

Saying a mark moves rules out a fixed corner badge, which is what almost every unqualified use of watermark in this subject means. It also rules out the standard workaround. A stationary badge can be reframed away in a single operation that costs nothing but composition; a travelling one cannot, because the safe region changes from second to second.

That makes motion the most consequential attribute a vendor can publish in one word. It says more about what a reader can and cannot do with the file than a position does, and it appears on exactly one page in this register.

2Why it is a deterrence choice rather than a visibility choice

A mark exists to be seen, and a stationary one in a predictable corner is seen perfectly well. Motion adds nothing to visibility and a great deal to removal cost, so a vendor choosing it is choosing to make the mark hard to get rid of rather than easy to notice.

Read that way, motion is evidence about intent that no pricing page supplies. It suggests the mark is there to persist rather than to advertise, which is consistent with the document it appears in: a safety enumeration rather than a feature list.

3What is still unpublished about it

Speed, path and whether the path is deterministic are all unstated. A mark that traverses slowly in a predictable pattern is a different problem from one that jumps, and nothing published anywhere here decides between them. Nor is size given, so how much of the frame is affected at any instant is unknown.

The register records the word and stops. That is the discipline everywhere here: a one-word attribute is worth a great deal more than nothing, and filling the surrounding detail from a sample clip would put an observation in a column of citations.

Nothing on this page is a vendor statement; the values it helps read are on the support table, with the page and the date each one was read from. See also the free tier column, metadata against watermark. Nearby terms: brand mark, invisible watermark, content credentials.
