Hedra publishes three rungs and no condition

The Character-3 page publishes 540p, 720p and 1080p, and attaches no length condition to any of them. Read beside the ten minute ceiling on the same page, that makes this the only row where a very long run and the top resolution are stated as compatible. As of 2026-09-22.

Inclusion rule. Values this model page publishes for Character-3. Figures for the vendor's other models are not carried on this sheet. Order. As the model page lists its fields.

1Three ladders on one page, none of them coupled

What distinguishes this row is not the values but their independence. Seven shapes, three resolutions and a ten minute ceiling are published as three separate lists, and nothing on the page says that choosing from one narrows another.

Two other rows in this register annotate a tier with a length, and one annotates a length with a tier. Here the combinations multiply out, which is either generosity or a page that has not been tested at the corners, and the register can only record which it says.

2540p at the bottom, for a product that runs long

A cheapest rung of 540p on a row whose ceiling is measured in minutes is a coherent pairing: long presenter footage is often delivered small, and a ten minute piece at 1080p is a large file to move around.

Against the advertising formats this register reads, the rung barely matters. Everything is under a minute, the published pixel floors are cleared at 540p, and the tier decision is about how the file looks rather than whether it is accepted.

3The widest shape list in the register sits beside this ladder

Seven ratios including 9:21 and 21:9 is the longest list published on any page here. Reading it with the resolution ladder, the row publishes more combinations of size and shape than anything else in the register, from a square 540p frame to an ultrawide 1080p one.

For a campaign that runs the same message across several surfaces, that is the property worth having. A vertical placement and a widescreen one can both be generated at their own shape rather than cropped from one master, and the crop is where a composition usually goes wrong.

4Where this cell sits in the column

Inclusion rule. Every generator in the register, carrying the resolution figure its own page prints, whether that is a ladder, a range or a single pair of numbers. Order. Alphabetical by generator name.
