What each generator documents about marking its output

SceneMixer gestures at metadata without naming it

SceneMixer's guide tells publishers to keep whatever content credentials or generation metadata the tool writes, and warns that re-encoding can strip them. It names no scheme and lists no field. As of 2026-09-12.

What has to be named before this cell is filledThree kinds of statement fill this column: a scheme named so a reader can look it up, a metadata key named so it can be checked in a file, or a signal whose behaviour is described. An instruction to preserve an unnamed layer is none of those, however clearly it implies one exists.What does the page say is inside the fileA named scheme or standardCell filledThree generators.

How the reading was takenRead as a gesture rather than a statement, because no scheme is named and no field is listed.

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.

1A sentence that implies something and states nothing checkable

The guide clearly implies that something is written into the file: publishers are told to keep it, and warned that re-encoding through an editor can strip it. Both halves of that advice presuppose a layer. Neither half says what the layer is.

A cell here needs a scheme named so it can be looked up, a key named so it can be checked, or a described signal. An instruction to preserve an unnamed thing gives a reader nothing to do with a file in hand, so the cell records not documented and the sentence is kept as a fact of its own on this page.

2Why the bar is set where it is

Lowering it would be easy and would ruin the column. Twelve generators record not documented here; several of their pricing pages mention metadata in passing, in the way that pages mention things. If a passing mention filled the cell, the column would stop distinguishing a vendor that publishes a specification from one that publishes a gesture.

The three cells that are filled all name something. Two name a standard and one names a scheme and the platform that reads it. That is the line, and it is drawn where it is because everything above it can be verified by a reader and nothing below it can.

3The warning is worth more than the implication

Re-encoding can strip that layer is the most useful part of the sentence, and it is the part that does not concern this vendor specifically. It is true of any manifest attached around a picture, which is the fragile half of the arrangement in this whole subject.

One other entry in this register publishes the same caveat about its own named credentials, which is the version a reader can act on. Here the advice arrives without a mechanism to apply it to, which is why the register files the warning and the empty cell as two separate facts on one row.
