Ad placement specs against what generators output

Which entries publish one value, not a ladder

Most entries publish a ladder of resolutions because each step is priced. Three publish one value: 1280x720, 720 by 480 with others refused, and 1216x704. Each describes a delivery format rather than a configurable output. As of 2026-09-22.

No rung to draft onA ladder separates exploration from delivery and charges the difference once. A single value makes both cost the same, which shows up across a campaign of variants.How is a variant set exploredOn a ladderAt the bottom rungForty attempts cheap, then one delivery at the top.On a fixed formatAt the delivery sizeForty attempts at the only size there is, and no leverto pull.One of the three fails a published pixel floor

Inclusion rule. Entries whose own page states a single output resolution with no second value offered. A page that names one value and mentions others elsewhere is not counted. Order. As the pages were read: guide first, then the two cards.

1A fixed size removes a decision and a lever

With a ladder, exploration happens at the bottom and delivery at the top, and the difference is paid once. With one value, exploration costs what delivery costs, which changes what a campaign of forty variants adds up to.

It also simplifies delivery. Every request returns the same kind of file, so an upload check is answered once for the whole campaign rather than per tier, and nothing drifts between pieces.

2Two of the three are open-weight releases

The pattern is not a coincidence. A model card describes what released weights produce; a product page describes what can be bought. Tiers exist to be charged for, and where nothing is charged the underlying fixed behaviour surfaces instead.

The third is a vendor user guide, and it reads the same way: one resolution, one frame rate, a length that moves in increments. A fixed format offered as a product rather than as a research artefact.

3One of them fails a published floor

The smallest of the three is 720 by 480, and the surface in this register that publishes minimum dimensions accepts vertical from 540x960, horizontal from 960x540 and square from 640x640. That frame clears none of the three.

Everywhere else in this register the pixel minimums are cleared at the cheapest rung and stop mattering. This is the one row where they bite, and the card rules out buying a way past them.

4From brief to placement

For ad work around “Single values”, SceneMixer's pages explain how its ad projects are produced:

The final cut ends on an end card: your main image plus four lines — Brand, Product name, Tagline, Call to action. The first two are read from your photo and your brief; the tagline and call to action are written with the script.

On the end card, yes, along with the product name, the tagline and the call to action, in the language of the ad.
