$10 wallet top-up: how many seconds of Seedance 2.5 and Wan 3.0

A $10 top-up buys about 17.3 seconds of 9:16 Seedance 2.5 at 720p, or 80 seconds of Wan 3.0 at 720p, on Sume. Seconds are a way to compare, since real clips need whole-clip prices and a minimum length of 4 seconds on Seedance and 2 on Wan.

A $10 purchase is the smallest on-demand amount listed in the pricing FAQ; the range goes to $1,000.

Seconds per dollar

Divide the wallet amount by the per-second price. Seedance 2.5 per-second prices below are for a 1-second 9:16 clip (token count is rounded up per clip, so longer clips cost a hair less per second).

What $10 means in clips

At 720p on Seedance 2.5 a 6-second clip is $3.4668, so $10 covers 2 of them. A 15-second clip is $8.667, so $10 covers 1.

On Wan 3.0 at 720p a 6-second clip is $0.75, so $10 covers 13.

Why holds matter at small balances

Each job reserves its estimate at submit. A $10 balance with a 15-second 720p Seedance clip in flight has $1.333 available for the next job.

A second 15-second clip then fails with 402 insufficient credits until the first settles or you top up. The errors and credits docs describe the lifecycle.

Choosing a first top-up

• Test runs: $10 is enough for several short drafts.
• Campaign batch: sum the clips and add a retake margin, as the top-up post explains.
• Rates can change; re-check pricing.
