Seedance 2.5 price per second at 480p, 720p and 1080p on Sume

Seedance 2.5 does not bill by the second. Sume prices it by video tokens, so the cost of one more second depends on the frame size. At 9:16 the arithmetic gives $0.2687 per second at 480p, $0.5778 at 720p and $1.4216 at 1080p, which makes 1080p 2.46 times the price of 720p rather than the 2.25 times the pixel count alone would suggest.

The rates and limits come from the Video Router docs (Seedance 2.5 accepts 4 to 30 seconds at 480p, 720p and 1080p; every video model bills at provider list times 1.25) and the API pricing rate card. All figures below were read on 2026-10-03.

How does Sume turn a Seedance 2.5 clip into a price?

The estimate counts video tokens as width x height x seconds x 24 frames per second, divided by 1,024, then multiplies by a per-1,000-token rate. That is why the same formula covers every duration and why a clip priced at 15 seconds is exactly three times a 5-second clip at the same frame size.

Seedance 2.5 is billed at $0.02675 per 1,000 tokens at 480p and 720p, and at $0.02925 per 1,000 tokens at 1080p. The table shows the 9:16 frame sizes the estimate uses.

Why is 1080p more than twice 720p?

Two things stack. A 1080 x 1920 frame carries 48,600 tokens per second against 21,600 at 720p, which is 2.25 times as many. The 1080p rate per token is also about 9 percent higher ($0.02925 against $0.02675). Together that is 2.46 times: $1.4216 per second against $0.5778.

Going from 480p to 720p is milder. 480p carries 10,044 tokens per second, so 720p costs about 2.15 times as much, with no change in the token rate.

What does a whole clip cost?

Multiply the per-second price by the length you need. The table gives common lengths at 9:16; other aspect ratios shift the total by a fraction of a percent, covered in the aspect-ratio post.

When is it worth stepping up a resolution?

Price is only half the question, since the same prompt does not render the same frames at a different resolution. For a test round, 480p keeps a 15-second clip near $4.03; for a final that will be watched full screen, 1080p at 15 seconds is $21.32, so it pays to confirm the hook at a lower step first. Wan 3.0 vs Seedance 2.5 lines the two up on inputs and limits, and the 480p draft post explains why a draft is not a preview of the final take.
