Ad placement specs against what generators output

In-feed video: a click or a watch-time view

An in-feed video ad sits among other content rather than inside a video stream. What is charged for varies: a click in some campaign types, a stretch of autoplay in others. Neither constrains the file at all. As of 2026-09-12.

Inclusion rule. Properties the format definition states. Campaign-type mechanics are recorded where a definition states them and are not inferred. Order. The property that varies most first.

1A billing rule can be a brief in disguise

Where a view is counted after a stretch of autoplay, the format has said where the thing worth paying for must happen. That is an instruction about structure rather than about the file, and it does not appear in any spec column.

Where a click is what is charged, the instruction is different again: the opening has to earn a deliberate action rather than passive attention, which usually means a clearer offer earlier.

2Nothing here constrains the generator

With no stated length, shape or resolution, the format imposes nothing a tool has to satisfy. Everything a delivery check looks at comes from the surface rather than from the format definition.

So an in-feed campaign is usually blocked by the shape a surface accepts rather than by anything in this entry, and the useful reading is on the placement sheet instead.

3Campaign type belongs in the brief

Because the billing rule changes with the campaign type, two in-feed placements bought differently want different edits. A piece optimised for a watch-time threshold is not the same piece as one optimised for a click.

That is a planning decision rather than a production one, and it has to be settled before the material is generated, because the difference is in the first few seconds.

A vocabulary entry: the definition, plus how the specification pages on these sheets usually publish it. Table checked 2026-09-12. Nearby entries: Impression, Paid view.
