Scene study: a shoe on a turntable · Prompt and scene notes
A single unbranded yellow running shoe turns slowly on a small circular white display stand. Rounded lavender and peach blocks form a clean studio background. Soft high-key light reveals the fabric and sole as the shoe rotates a quarter turn. Stable side-on product framing, one continuous five-second shot. No lettering, no logo, no watermark.
The turntable illustration gives you a focused brief to adapt for Seedance 2.0 Fast: one shoe turns against a stable background. Inspect the outline and laces throughout the rotation. The displayed Wan 3.0 clip does not measure this variant’s output quality or completion time.
These illustrations were generated with standard Wan 3.0. They are not Seedance outputs or a comparison of model quality.
Seedance 2.0 Fast · Pricing
Seedance 2.0 Fast has its own live token rates. The table shows per-second estimates for 16:9 output at 24 fps, helping you compare the settings for a short motion test.
Current ratesEstimated USD / billable second
| Resolution | Reference video | Official price | Funny AI price | You save |
|---|---|---|---|---|
| 480p | No video | $0.0506 | 10% | |

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. Funny AI prices refresh automatically.
Input and output video tokens determine the final cost. Failed requests are not charged.
Reference video adds billable input to Seedance 2.0 Fast and can introduce a minimum usage threshold. Match length, resolution and references when comparing estimates; silent output does not use a separate lower token rate.
What is Seedance 2.0 Fast?
Seedance 2.0 Fast is a separate ByteDance video model for clips between four and fifteen seconds, with automatic duration also available. It offers 480p and 720p output with optional sound. You can start with text, establish a composition with frames or bring reference material for the subject and movement.
A small product rotation is one way to evaluate Seedance 2.0 Fast. Define the starting angle, the amount of the turn and a camera position that stays fixed, then watch whether the object remains recognizable. Record completion time separately from visual quality; the model name is not a measured speed promise on Funny AI.
Documented model ID
bytedance/seedance-2.0-fastSeedance 2.0 Fast accepts up to 9 reference images, 3 videos and 3 audio clips. Reference video and reference audio each have a separate fifteen-second total.
The settings below follow this model’s specification and the controls available on Funny AI. Check the integration guide for input requirements.
Direct a focused movement
Set the visual endpoints
Supply Seedance 2.0 Fast with a first frame and, optionally, a last frame. Use this mode when the opening and destination matter more than a collection of separate examples.
Separate the subject from the movement
In Seedance 2.0 Fast reference mode, an image can describe the subject while video suggests its motion. Name each source’s role in the prompt to keep the direction clear.
Include sound in the brief
Request generated sound with Seedance 2.0 Fast, or disable it for a later edit. An audio reference requires an accompanying reference image or video; the soundtrack should be reviewed with the picture.
Try the movement in your browser
Prepare Seedance 2.0 Fast in the Playground and inspect its input settings. Check current availability and the estimate before submitting the scene you want to test.
Use Seedance 2.0 Fast in your app
Select the Seedance 2.0 Fast identifier in your code and follow its API guide. Save the returned task ID with the request for later status checks and result retrieval.
Short scenes with one clear action
A product turning toward the viewer
Give Seedance 2.0 Fast a modest rotation to explore, with a fixed background and camera. The outline, material and small details provide specific points to check throughout the movement.
A detail entering the frame
Use Seedance 2.0 Fast to explore a short reveal: an object moves into view or the camera passes an edge. Describe which element moves so the direction is easy to judge.
An insert for a social edit
Create a Seedance 2.0 Fast shot that carries one visual idea within a larger sequence. Choose the intended aspect ratio and plan an ending that can connect to the next clip.
Prepare a matched motion test
- 01
Name the movement
Tell Seedance 2.0 Fast what the subject does and where the camera sits. Replace vague energy instructions with a visible action you can assess.
- 02
Choose the right anchor
Use frames with Seedance 2.0 Fast for defined endpoints, or references when appearance and motion come from different files. Keep those input modes separate.
- 03
Keep the comparison consistent
Match Seedance 2.0 Fast and Mini settings when evaluating the same brief. Hold the length, resolution and source material steady, then compare the complete results.
- 04
Review picture and time separately
Save the Seedance 2.0 Fast task and watch the entire clip. Record elapsed time separately so a pleasing image does not become an unsupported claim about speed.
Integrate Seedance 2.0 Fast
The Seedance 2.0 Fast guide documents the selected model, input combinations and task retrieval. Submit once and retain the accepted task ID. If a status request is interrupted, resume checking that task instead of sending a duplicate paid generation.
Integration guideFast and Mini: compare the same shot
Seedance 2.0 Fast and Mini share the documented duration range, resolution choices and reference counts. Their model identities and current rates are separate. Compare matching briefs and usable results rather than treating their names as a quality or speed ranking.

Seedance 2.0 Fast limits
- Seedance 2.0 Fast stops at 720p and does not offer Draft mode. Standard 2.0 has larger output tiers; 2.5 offers a longer single-clip duration.
- A last frame requires a first frame in Seedance 2.0 Fast. Frame inputs cannot be combined with the mixed reference collection.
- Seedance 2.0 Fast video and audio references each total at most fifteen seconds. This integration does not expose editing, extension or a separate final-frame image output.
Keep the motion test easy to review
Funny AI shows Seedance 2.0 Fast rates and the estimate for your selected inputs. Review those figures before deciding how to test the brief.
Inspect the prepared Seedance 2.0 Fast fields in the Playground, with its own API documentation available for the next step into your application.

Seedance 2.0 Fast vs Mini: plan a matched testSeedance 2.0 Fast questions
Is Seedance 2.0 Fast guaranteed to finish sooner?
No measured completion-time guarantee is provided for Seedance 2.0 Fast here. Treat Fast as the model name and record the elapsed time of your own request separately. A useful comparison also checks whether the complete clip meets the brief, using the same settings and references for each model.
Can Seedance 2.0 Fast generate 1080p?
No. Seedance 2.0 Fast offers 480p and 720p at 24 fps, with four-to-fifteen-second or automatic duration. Use standard 2.0 when its larger output tiers fit your delivery requirements. The Playground defaults for this variant are a five-second clip at 720p.
Can reference footage guide Seedance 2.0 Fast?
Yes. Seedance 2.0 Fast accepts up to three reference-video clips totaling at most fifteen seconds. You can combine them with supported image and audio references in reference mode. Describe which file supplies the subject and which supplies the motion, keeping first/last-frame inputs outside this collection.
Does silent Seedance 2.0 Fast output cost less?
Seedance 2.0 Fast has no separate lower token rate for silent output. Duration, output size and reference-video usage still determine the estimated total. Turn audio off when the creative brief calls for silence or the edit will supply its own sound, then check the live estimate.
Did Seedance 2.0 Fast generate the shoe video?
No. The shoe illustration was generated with standard Wan 3.0 for five seconds at 480p. It is a scene idea to adapt for Seedance 2.0 Fast, with its actual model identified beside the player. Use a separately generated result when assessing this variant’s motion or completion time.
