Ad placement specs against what generators output

Fitting HeyGen output into YouTube ad formats

HeyGen publishes a page of limits rather than a price grid: thirty minutes per scene, fifty scenes per video, 16:9 or 9:16, and output dimensions given as a range from 128 to 4,096 pixels on each side. Every ad format in this register fits in a single scene. As of 2026-09-22.

A page of limits reads unlike a page of pricesThirty minutes per scene, fifty scenes per video, two aspect ratios and output dimensions given as a range from 128 to 4,096 pixels. None of those four is a lever anybody charges for, which is why none of them would appear on a pricing table.On a pricing pageOn a limits pageLengthA duration you pay forThirty minutes per sceneStructureNot mentionedFifty scenes per videoOutput sizeA tier such as 1080p128 to 4,096 px each sideUploadsNot mentioned100MB video, 50MB image or audioSame vendor, different question answered

Inclusion rule. Formats from Google's own help page, matched only against limits the tool vendor publishes. Where either side does not state a value, the row says so rather than estimating. Order. Shortest format first, as on the placements page.

2Limits published as limits, which reads differently

Almost every vendor figure on these sheets is a by-product of billing: a duration appears because a duration is charged for, a resolution appears because each rung costs more. This page exists to say where the walls are, and the difference shows in what it covers. Scene count, upload ceilings and a pixel range are not priced levers, and none of them would appear on a pricing table.

For matching against an ad slot the effect is that the length column stops mattering and the shape column starts. Thirty minutes per scene clears every format here without discussion, while 16:9 or 9:16 is a firm choice of two that has to be made before anything is generated.

3A pixel range instead of a resolution ladder

Width and height each between 128 and 4,096 pixels is a different kind of statement from 720p or 1080p. It describes a space of legal outputs rather than a set of tiers, so a request can ask for the exact pixel dimensions a placement wants instead of picking the nearest rung and living with the shape that comes out.

The megabyte figures on the same page belong to uploads rather than output: 100MB for a video going in, 50MB for an image or an audio file, 32MB for an asset. They are worth recording because the file column on these sheets is otherwise empty on the vendor side, but they answer a question about what goes in, not about what an ad platform will be asked to accept.
