Hedra publishes ten minutes, driven by audio
The Character-3 model page states a maximum duration of ten minutes. Nothing this register reads on the placement side comes close, so the cell is accurate and inert at once, and what it actually describes is how long a performance can be sustained. As of 2026-09-22.
| Figure | Value | What sets it |
|---|---|---|
| Max duration | 10m | How long the supplied audio runs |
| Longest ad slot in this register | 60 seconds | A platform help page |
| Headroom | Nine minutes on any slot recorded here | Not a usable quantity |
Inclusion rule. The duration figure this model page states, set against the longest placement ceiling this register carries. Figures for other Hedra models are not recorded on this sheet. Order. The published figure first, then what it is being read against.
1A ceiling that nothing reaches is still worth printing
Ten minutes answers no question a media buyer has. Its value in the register is comparative: it marks this row as belonging to a different product category from the scene generators, whose longest single runs are measured in tens of seconds.
Reading it as headroom is the error the cell invites. Headroom implies the constraint has moved somewhere else, and here it has: to whether a speaking performance is the right form for the advertisement at all, which no spec sheet settles.
2Length governed by audio is length governed by a script
Where a model animates a supplied audio track, the output runs as long as the track. The ceiling is then a statement about file handling rather than about how long a coherent scene can be held together, which is what the same number means on a prompt-driven row.
That is why this register refuses to rank the column. Ten minutes here and thirty seconds on a scene generator are not the same quantity measured twice, and a table that sorted them into an order would be publishing a category error as a finding.
3What the resolution ladder adds to the reading
The same page publishes 540p, 720p and 1080p, with no condition tying any of them to the length. A ten minute piece at 1080p is available in the terms the page states, which is unusual: two other rows here couple their longest run to a resolution.
For a sixty second non-skippable that combination is the whole appeal. One request, one continuous performance, no joins to match and no tier to give up, against a format whose impression billing charges for every second including the ones a seam would spoil.

Inclusion rule. Every generator with a row in this register, carrying whatever its own page states as a length. A page that states none keeps its row and says so. Order. Alphabetical by generator name.
