Ad placement specs against what generators output

SceneMixer publishes thirty seconds and a composite

The price list states thirty seconds as the longest single generation for Wan 3.0 and Seedance 2.5 jobs and fifteen for Seedance 2.0 and MiniMax H3 jobs, then states how length past that is reached: segments composited into an episode, billed at one credit per second of output. As of 2026-10-13.

Inclusion rule. Figures the price list states about how long output runs, including the priced step for assembling segments. Tier names are recorded as the page gives them. Order. Longest tier ceiling first, then the step that goes beyond it.

1Thirty seconds is the widest prompt-driven call here

Among rows that generate a scene from a prompt rather than a performance from an audio track, thirty seconds is the top of this column. It covers three of the six YouTube formats outright: the bumper, the Masthead autoplay window and the mark at which a skippable view is charged.

It also sets the floor on join count for the format that does not fit. A sixty second non-skippable is two calls and one join, which is the fewest any scene generator in this register manages, and one join is a materially different edit from seven.

2The tier decides the ceiling, so the ceiling is a purchase

Fifteen seconds and thirty seconds are both published on the same page as properties of different tiers. A shot list written at thirty is a shot list committed to the Wan 3.0 or Seedance 2.5 tiers, and a job that lands on a fifteen-second tier for cost reasons has quietly doubled its piece count.

This register records both rather than the larger, for the same reason it records two ranges on the row that publishes one per model. A ceiling that only exists at a price is a conditional ceiling, and the condition belongs in the cell.

3A published assembly step is unusual in this column

Most rows stop at the clip ceiling and leave what happens next to an editor. This one names the next step and prices it: segments composited into an episode at one credit per second of output. The joining work stays inside the tool and inside the invoice.

What that does not do is make the joins good. A documented compositing step says where the seams are handled, not whether a face and a key light survive them, and no page in this register publishes anything about that.
