What each generator documents about marking its output

Corner stamp: the least intrusive way to mark a frame

A corner stamp occupies one corner of the frame and leaves the rest of the composition alone. It is the cheapest mark to apply, the least damaging to footage, and the one a reframe removes most easily. As of 2026-09-22.

Three geometries, and what each leaves behindA corner stamp leaves the composition usable and can be excluded by a reframe. A moving mark defeats reframing because it does not stay in one region. A mark that covers the frame leaves nothing outside itself to keep, which makes the output a demonstration rather than footage.How much of the frame does the mark occupyOne cornerBranded footageUsable in a cut, andexcludable by a reframe ifit falls outside the newframe.A path across the frameReframe-resistantNo single region containsit, so cropping cannot berelied on to exclude it.The whole pictureA demonstrationNothing outside the markremains, so the output isnot footage at all.Geometry decides what the material is good for

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.

1The geometry decides what the footage is good for

Output with a corner stamp is branded rather than unusable. A cut can be built from it, a client can review it, and in some formats the stamp lands where a caption bar or a platform overlay would sit anyway. That is a very different situation from material a mark has made undeliverable.

Which is why two cells that both read watermark are not the same finding. A register that recorded only the presence of a mark would put a corner badge and a full-frame overlay in the same state, and a reader planning around either one would be planning around the wrong object.

2Corner is a weak position and a specific one

Knowing the corner narrows what a reframe achieves without settling it. A vertical crop of a horizontal generation may exclude a lower-right stamp entirely; a modest safe-area trim may not. Nothing here answers that for any entry, because size is unpublished everywhere even where position is not.

It is still the most specific geometric fact any vendor in this register publishes. One entry gives both the words of its stamp and the corner it occupies, which is enough for a reader to compare a file against a page rather than against a memory of one.

3Why so few pages say where the mark sits

A pricing grid has no reason to. Position is not a selling point in either direction: printing it makes the free tier look worse and the paid tier no better, and a grid exists to make an upgrade obvious rather than to specify an artefact.

Position tends to appear where a document is written for somebody who has to act on it. Interface references publish it because a caller may need to place a caption elsewhere; console instructions publish it because an operator will see it. Detail follows the purpose of the page.

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: full-frame mark, moving mark, brand mark.
