Which entries never mention output shape
Six entries in this register publish nothing about output shape. Four are pages that are thin on output specifics generally. One publishes 720 by 480 and refuses other sizes. One publishes 1280x720 and is otherwise precise about everything else. As of 2026-09-22.
| Item | What is published | Detail |
|---|---|---|
| Priced pages with no shape column | Two entries | Both also state no duration |
| Model cards with a fixed pixel size | Two entries | Exact sizes, frame rates, no ratio |
| A precise page that skips shape | One entry | One resolution, one frame rate, a length rule, no shape |
Inclusion rule. Entries whose own page never addresses output aspect ratio. A resolution that implies a shape by arithmetic is not recorded as a published shape. Order. Grouped by the kind of page, most entries first.
1Why an implied ratio does not fill the cell
1280 by 720 is sixteen by nine. Writing that in the shape column would make the row look like the entries that publish two or more shapes, and it would be wrong in the way that matters: those pages say a vertical output exists and this one does not.
A single pixel pair says what one output looks like. It cannot say whether the parameter accepts another value, and a placement plan needs the second answer.
2The consequence is that vertical cannot be planned
Most short-form advertising runs vertical. A page that names one widescreen resolution and no shape parameter gives a buyer nothing to book a vertical placement against, whatever the product may be capable of.
That is sharper than a missing tier. Resolution can be revisited after a render and shape cannot, so an unanswered shape question blocks the brief rather than the delivery.
3Five of the six silences are ordinary
Two are rate cards that print resolutions and nothing else, two are model cards describing research releases, and one is a rate card with a 4K tier. In each case the whole page is thin on output specifics and the shape gap is part of that.
The sixth is the exception: a page precise about resolution, frame rate, a length rule and a model identifier condition, silent on shape alone. That one silence is a decision rather than a general thinness, which is why it gets a cell page of its own.

4A generator's ad pipeline
For ad work around “Nothing about shape”, SceneMixer's pages explain how its ad projects are produced:
Character sheets are always portrait and scene images always widescreen, whatever ratio the videos use.

16:9 landscape (SceneMixer's default) and 9:16 vertical (the usual short-drama frame), chosen per project.
