Seedance 2.0 Fast: a beach tracking shot · Prompt and review
A golden retriever runs along a beach at sunset, splashing through shallow waves, tracking shot
The Seedance 2.0 Fast sample follows a moving dog through shallow water. Watch the paws, body shape and splashes as the camera tracks alongside. The sample demonstrates this particular scene; it does not measure current generation speed.
A sample illustrates one result. It does not guarantee the same quality, timing or output on another prompt.
Pricing
Seedance 2.0 Fast · Pricing
Seedance 2.0 Fast prices below are calculated from current rates for 16:9 video at 24 fps. Check both input modes before choosing a setting: reference video contributes billable time as well as the generated output.
Current ratesEstimated USD / billable second
| Resolution | Reference video | Official price | Wan API price | You save |
|---|---|---|---|---|
| 480p | No video | $0.0562 | Unavailable | — |

Estimates use 16:9 output at 24 fps. Other aspect ratios and actual output dimensions can change the cost.
Without reference video, only output seconds count. With reference video, input and output seconds count; billable input time is at least two-thirds of the output duration, rounded up to a whole second.
Official comparison: BytePlus international on-demand pricing. Checked 2026-10-15. Wan API prices refresh automatically.
Input and output video tokens determine the final cost. Failed requests are not charged.
The Seedance 2.0 Fast estimate changes with duration, output dimensions and video references. Audio has no separate price tier. A lower rate per token with reference video does not necessarily mean a lower total cost for the shot.
Readme
What is Seedance 2.0 Fast?
Seedance 2.0 Fast is a separate member of the ByteDance video family, with its own model identifier and pricing. It accepts text and reference media, generates clips from four to fifteen seconds, and offers 480p or 720p output.
Use Seedance 2.0 Fast when your next decision concerns motion: whether a tracking shot keeps pace, a subject remains recognizable, or an action reaches a useful endpoint. A successful test should answer that decision before you add more events to the scene.
Documented model ID
bytedance/seedance-2.0-fastSeedance 2.0 Fast accepts up to nine reference images, three video clips and three audio clips. Each media type has additional file and duration requirements; reference audio must accompany an image or video.
Model capabilities and service availability are listed separately. Output options may depend on the selected model version and input mode.
Direct a scene with Seedance 2.0 Fast
Give Seedance 2.0 Fast an opening and ending
Provide a first image to establish the opening, or add a last frame to describe the destination. Frame inputs belong to their own mode and cannot be mixed with the reference collection.
References separate appearance from motion
Use Seedance 2.0 Fast image references for appearance and a video reference for movement. Explain the role of each asset, especially when the source clip contains a different subject or setting.
Sound belongs in the brief
Seedance 2.0 Fast can generate sound with the picture. Specify waves, footsteps or speech deliberately, then listen to the complete result. Disable generated audio when the edit needs a silent source clip.
Try Seedance 2.0 Fast in the Playground
Write a brief for Seedance 2.0 Fast, select an input mode and inspect the request before generating. Keep one main action so changes between attempts have a clear purpose.
A repeatable application request
Use the Seedance 2.0 Fast integration guide to carry a tested brief into your application. Save the settings alongside the returned task ID so you can associate each result with its inputs.
Where Seedance 2.0 Fast fits
Action and camera studies
Test a short tracking or reveal shot with Seedance 2.0 Fast before expanding the sequence. Evaluate whether the subject stays visible and whether the camera move supports the intended action.
Product movement concepts
Use a product image to anchor a turn, lift or reveal. Inspect geometry and labels throughout the video: a recognizable opening frame does not establish that the product remains accurate later.
Social video variations
Try one change at a time with Seedance 2.0 Fast: framing, movement or the endpoint. Keep the aspect ratio aligned with the destination and compare complete clips rather than attractive thumbnails.
Plan a Seedance 2.0 Fast test
- 01
Choose the decision
Write down what the Seedance 2.0 Fast result must establish. For the dog sample, that could be continuous running with the animal fully visible and no unexpected cut.
- 02
Prepare only useful references
Remove references that conflict in lighting or identity. Use a first frame for a defined opening, or choose reference mode when multiple assets describe different aspects of the shot.
- 03
Keep the settings comparable
Start Seedance 2.0 Fast at five seconds and 720p. When comparing another model, keep the prompt, duration, aspect ratio, audio setting and reference files the same.
- 04
Review and revise one failure
Watch the Seedance 2.0 Fast result at full size, then listen separately. Name a concrete problem such as a changing paw or an abrupt camera move before revising the brief.
Integrate Seedance 2.0 Fast
The Seedance 2.0 Fast guide includes the model identifier, request fields, reference rules and task retrieval example. Submit once, keep the returned task ID and retrieve that task until it finishes. The request preview lets you inspect the same input contract used by the Playground.
Integration guideSeedance 2.0 Fast or Mini?
Seedance 2.0 Fast and Mini share a fifteen-second maximum, 480p/720p output and the same reference counts. Those specifications cannot establish which produces a usable result for your brief. Compare current prices and matching shots; this page makes no measured latency claim.
| Model | Output options | Wan API price |
|---|---|---|
| Seedance 2.0 Fast | 480p / 720p | Price unavailable |
| Seedance 2.0 Mini | 480p / 720p | Price unavailable |
Before choosing Seedance 2.0 Fast
- Seedance 2.0 Fast does not offer 1080p, 4K or Draft mode. Choose the standard model or Seedance 2.5 when their different output settings are required.
- The Seedance 2.0 Fast reference inputs have separate limits: video clips must total at most fifteen seconds, and audio clips must also total at most fifteen seconds. A last frame requires a first frame.
- Seedance 2.0 Fast can change fine details, lettering or subject appearance during motion. Editing, extension and returning a final-frame image are not exposed by this Wan API integration.
Evaluate Seedance 2.0 Fast on Wan API
Seedance 2.0 Fast has its own live price table. The Playground shows an estimate before submission; final cost follows actual usage. Failed requests are not charged.

Seedance 2.0 Fast vs Mini: which should you test?Seedance 2.0 Fast questions
How long does Seedance 2.0 Fast take?
Seedance 2.0 Fast is the model name, not a completion-time guarantee. We have not measured a controlled latency comparison on Wan API. Record elapsed time alongside output quality when testing your own brief.
Which resolutions and durations can I choose?
Seedance 2.0 Fast supports 480p and 720p, with integer durations from four to fifteen seconds or automatic duration. The default is five seconds at 720p. Output is MP4 at 24 fps.
Can I use only an audio reference?
No. Seedance 2.0 Fast reference audio needs a reference image or video. To describe ambience without supplying media, use the prompt and keep generated audio enabled.
Is this the standard 2.0 model?
No. Seedance 2.0 Fast has a separate identifier, output limits and rate table. A request intended for standard 2.0 should be checked before switching, particularly if it selects 1080p or 4K.
Can I try the sample before signing in?
Yes. Playing the existing Seedance 2.0 Fast sample is free. Creating your own clip requires signing in, an available generation service and enough balance for the displayed estimate.
