Ad placement specs against what generators output

Fitting MiniMax output into YouTube ad formats

The MiniMax reference publishes two models with deliberately different edges: four to fifteen seconds at 768P or 2K on MiniMax-H3, five to fifteen at 480P or 768P on H3-Max, where four seconds and 2K are both stated as unsupported. As of 2026-09-22.

Two models named by what each refusesThe reference states four to fifteen seconds at 768P or 2K on MiniMax-H3, and five to fifteen at 480P or 768P on H3-Max where four seconds and 2K are both unsupported.

2A reference that publishes what each model refuses

Most pages in this register list what is available. This one lists exclusions alongside: four seconds is not supported on H3-Max, 2K is not supported on H3-Max. Those sentences carry more planning information than the ranges do, because they say which of two nearly identical models a given brief has to use.

A five second bumper runs on either. A four second one runs on only one of them, and a piece that needs 2K runs on the other, so a campaign with both requirements is a campaign that has already decided it is generating twice. None of that is visible from a price per second.

3The ratio is required, which is rarer than it sounds

For text-to-video the reference states that the ratio is required and cannot be adaptive, and gives six values from 21:9 down to 9:16. Required is the useful word: a request that omits the shape does not quietly receive widescreen, it does not run. On a site whose recurring finding is that shape gets decided by a default nobody read, that is a design choice worth pointing at.

For image-to-video the same page says the ratio follows the input image and is always adaptive, which moves the decision to whoever prepared the reference frame. The shape is still determined before generation, but by a file rather than by a parameter, and that file is usually chosen for its content rather than its dimensions.
