How Much Does Seedance 2.5 Cost? Per Second & Per Clip

Seedance 2.5 pricing is token-based. On APIMart, a Seedance 2.5 video without a reference video costs $10 per 1M tokens at 480p and 720p, which works out to about $0.096 per second at 480p and $0.216 per second at 720p. A 5-second 720p clip costs about $1.08, and a 30-second 720p clip about $6.48. With a reference video, the rate drops to $6 per 1M tokens, but the reference duration is billed too. 1080p is billed at $11 per 1M tokens (or $6.568 with a reference video).

For comparison, BytePlus ModelArk lists Seedance 2.5 at $10.70 per 1M tokens without video input and $6.40 with video input for 480p and 720p (official pricing).

Key Takeaways

• Seedance 2.5 is billed by tokens, not by flat per-second rates. Per-second prices are estimates used to precharge a task.
• On APIMart (Gold): $10 / 1M tokens for 480p and 720p without a reference video, $6 / 1M tokens with one; $11 and $6.568 / 1M tokens at 1080p.
• In seconds: about $0.096/s at 480p and $0.216/s at 720p without a reference video.
• With a reference video you pay (reference duration + generation duration) × the reference-video rate.
• Clips run 4 to 30 seconds at 480p, 720p or 1080p. There is no 4K for Seedance 2.5 on APIMart.
• You only pay for successful generations, and there is no free tier.

How Much Does Seedance 2.5 Cost?

Here is the full Seedance 2.5 price list on APIMart (Gold member prices, October 2026):

With Seedance 2.5, higher resolution means more tokens per second, so a 720p Seedance 2.5 video costs a little over twice as much per second as 480p even though the token price is the same.

Membership lowers Seedance 2.5 pricing further. Gold members get 20% off APIMart's list price, and Platinum and Diamond members get up to 28% off. For example, 480p and 720p without a reference video cost $9.50 / 1M tokens for Platinum and $9 / 1M tokens for Diamond.

Is Seedance 2.5 Billed per Second or per Token?

Per token. Seedance 2.5 settles on the tokens a video actually uses. The token count grows with resolution, aspect ratio and duration.

Because the exact Seedance 2.5 token count is only known after generation, APIMart works in two steps:

1. Precharge. When you submit a task, APIMart reserves an estimate based on the per-second rate for your resolution and duration. If you choose Auto duration, it reserves 30 seconds of output.
2. Reconcile. When the task succeeds, the charge is settled on the actual tokens used. Any difference is refunded or charged.

That is why your final Seedance 2.5 charge can differ slightly from the estimate. Failed tasks are not charged.

How Is Reference Video Billed in Seedance 2.5?

When you pass a reference video to Seedance 2.5, two things change:

• The token price drops to the reference-video rate ($6 / 1M tokens at 480p and 720p on APIMart).
• The reference video's duration is billed too, on top of the generated duration.

The formula is (reference duration + generation duration) × reference-video price.

Example at 720p: a 10-second reference video plus a 10-second output is billed as 20 seconds × ~$0.130 = about $2.59. The same 10-second output without a reference video costs about $2.16.

So in Seedance 2.5 pricing, a reference video costs less per second, but a long reference clip can still raise the total. Trim reference videos to the part you actually need. A reference video must be at least 2 seconds long.

Seedance 2.5 Pricing per Clip: 5, 10, 15 and 30 Seconds

Estimated Seedance 2.5 cost per clip on APIMart without a reference video (Gold member prices):

For reference, BytePlus's own pricing examples put a 5-second 16:9 clip without video input at $0.514 at 480p and $1.156 at 720p.

For 1080p, use the token price ($11 / 1M tokens without a reference video) and the live estimate on the Seedance 2.5 model page, since 1080p uses far more tokens per second than 720p.

Seedance 2.5 vs Seedance 2.0 Pricing

Seedance 2.5 costs more than Seedance 2.0. Per-second prices on APIMart without a reference video (Gold):

What the extra cost buys: native clips up to 30 seconds, up to 50 references (30 images, 10 videos and 10 audio clips), and synced audio. If you need 4K or the lowest cost per second, Seedance 2.0 is still available on APIMart with the same API key.

Seedance 2.5 Pricing: APIMart vs Official BytePlus

Here are both sets of Seedance 2.5 prices side by side, per 1M tokens:

Why Is Seedance 2.5 So Expensive, and How Can You Cut Costs?

Seedance 2.5 generates long, high-resolution clips with audio in a single pass, and every extra second and every extra pixel adds tokens. A few habits keep Seedance 2.5 costs down:

• Draft at 480p first. Use 480p to test prompts and references, then render the final version at 720p or 1080p. Seedance 2.5 also has a draft mode: a 480p draft task, followed by a separate 1080p final task. Each task is billed on its own.
• Set an explicit duration. Seedance 2.5 Auto mode reserves 30 seconds up front. If you know you need 8 seconds, ask for 8.
• Keep reference videos short. Reference duration is billed, so trim it.
• Test with short clips. A 5-second Seedance 2.5 test at 480p costs about $0.48.
