How many seconds of AI video does $20 buy on Sume, by model?

A $20 top-up is a common first purchase, and the useful question is how much footage it buys. Sume bills each video row at the provider list price times 1.25, per output second, so the answer is a division. The table below divides $20 by each billable rate and rounds down to whole seconds, which is the footage you can finish before the balance runs out.

Two caveats. Each job is rounded up to the cent on its own, so many short clips cost slightly more than one long one of the same total length. And the Seedance rows bill per video token rather than per second, so they are left out here.

How many seconds does $20 buy per row?

Resolution is the lever. Within one row, going from the cheapest to the most expensive tier cuts your footage by a factor of three to ten. Across rows at a matched resolution, Wan 3.0 and the MiniMax rows are closest in price at 480p.

What does that mean in clips?

Divide by your clip length. At 480p, 320 seconds is 64 five-second clips from Wan 3.0 or H3 Max, and 106 three-second clips from the same budget. At Gemini Omni Flash 1.1's 720p default, 160 seconds is 20 eight-second clips, each with native audio, which is the length Auto uses when you send none.

Kling Video v3 Pro is a single card with two rates, so its audio switch moves the number from 142 to 95 seconds.

Which number should I plan on?

Plan on the resolution you will ship, not the cheapest one. A draft pass at 480p is a good way to test prompts, but the final render is billed again at its own rate. Reserve the final-tier cost times the number of keepers, and treat the draft pass as overhead.

Rates can change. Read pricing from GET /v1/video-router/models before you budget a batch, and see the cost calculator post for how to turn the catalog fields into a quote.
