Why resolution is published and shape is not
The densest column on a specification sheet is usually resolution and the emptiest is usually shape. That is not a statement about which matters more to an advertiser. It is a statement about which one a vendor has to print in order to charge for it. As of 2026-09-12.
| Column | Usually published | Reason |
|---|---|---|
| Resolution | Almost always | Each step carries a different rate |
| Duration | Often | Sometimes billed, and always a request field |
| Aspect ratio | Rarely | Not usually charged for |
| Frame rate | Almost never | Not charged for and rarely a field |
Inclusion rule. Columns this kind of register carries, ranked by how often a specification page fills them. The reason column is an explanation rather than a vendor statement. Order. Most frequently published column first.
1The pricing model decides the paperwork
A vendor that charges per resolution step has to list the steps. A vendor that charges per second of output has to say so. A vendor whose rate does not vary with shape has no reason to mention shape on the page that carries the rate.
So a page can be complete on its own terms and useless for the one column a campaign is blocked on. Reading which document a figure came from is how a buyer knows in advance which columns will be empty.
2Shape is the expensive column to get wrong
Resolution is a quality decision that can be revisited: a piece can be re-exported or re-rendered at a different tier. Shape is a gate. A vertical placement does not take a widescreen file, and cropping into the shape moves the subject rather than tightening it.
That is the mismatch this kind of register exists to surface. The column that is cheapest to publish is the one that can be fixed later, and the column that decides whether the piece exists at all is the one most often left out.
3An empty column is not an absent capability
Almost every product that generates video can produce a vertical frame. What is missing from many pages is the statement, and a media plan that has to be signed off runs on statements.
The practical consequence is a question rather than a verdict. Where the shape column is empty, the answer probably exists somewhere, and a schedule has to hold a gap open until somebody gets it in writing.
A craft note, not a spec. Nothing here is taken from a platform or a vendor, and nothing here should be quoted as a requirement. The sourced material is on published limits. Related: Planning a join, Safe areas.

For ad work around “Why a ladder exists”, 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.

The photo is cleaned into a product shot and that object appears in every shot.
