Seedance API pricing: 5 credits per second, 3 to 15 seconds

Seedance 2.0 Fast bills 5 credits per second at 1080p, so the default 5-second clip costs 25 credits. It is the cheapest video model on Genace and the only one with genuinely linear pricing.

The formula, exactly

const perSec1080 = 5;
const factor = p.resolution === '720p' ? 0.5 : 1;
const credits = Math.ceil(p.durationSec * perSec1080 * factor);

Two things worth noticing:

720p is half price. Not “cheaper” — exactly half, then rounded up. A 5-second 720p clip is ceil(5 × 5 × 0.5) = 13 credits instead of 25.

Math.ceil means odd 720p durations round up. A 3-second 720p clip is ceil(7.5) = 8 credits, not 7.5. The rounding only ever costs you a fraction of a credit, but it is there.

Duration range

durationSec: z.number().int().min(3).max(15).default(5)

Any integer from 3 to 15. That is the widest range of the three video models, and it is the reason Seedance is the cheapest way to produce variable-length output — you pay for the seconds you actually asked for rather than rounding into a fixed bucket.

Duration	1080p	720p
3s	15 credits	8 credits
5s	25 credits	13 credits
10s	50 credits	25 credits
15s	75 credits	38 credits

In dollars

At the Enterprise pack rate ($0.0100 per credit), a 5-second 1080p clip is $0.25. At the Basic pack rate ($0.0138) it is $0.35.

The full ladder for the default 5-second 1080p clip:

Pack	Per credit	5s at 1080p	5s at 720p
Basic	$0.0138	$0.35	$0.18
Standard	$0.0124	$0.31	$0.16
Premium	$0.0116	$0.29	$0.15
Enterprise	$0.0100	$0.25	$0.13

Aspect ratios

Five options: 16:9, 9:16, 1:1, 4:3, 3:4. That is more than Veo 3 and Kling, which both drop 4:3 and 3:4. Aspect ratio does not affect price.

The “Fast” in the name

This is Seedance 2.0 Fast, the speed-optimised variant. Genace uses it as the default video model precisely because it is the cheapest and quickest option in the lineup — the tradeoff against the Pro variant is output quality, which this page makes no claim about.
