Input rejected
Check the selected mode, file types and duration. Edit and Extend need one source video and a prompt. Keep total reference video and audio lengths within their separate limits.
Seedance 2.5 AI Video Generator
Create video up to 30 seconds from text, images, video, and audio. Preview a draft before rendering the final clip, or use a prompt to edit or continue a video.
What is Seedance 2.5?
Seedance 2.5 creates longer takes from text, images, video, and audio. Use a short draft to check the motion before rendering a final, or start with a video to revise the action or generate a separate continuation.
Seedance 2.5 settings in this workspace
These are the options and limits checked by the generator before a request is sent.
| Setting | Available option |
|---|---|
| Starting point | Text prompt, first-frame image with optional last frame, or multiple media references |
| Output duration | 4–30 seconds |
| Resolution | 480p / 720p / 1080p |
| Reference file count | Up to 30 images, 10 videos, and 10 audio clips |
| Reference length | Up to 30 seconds of video and 30 seconds of audio in total, counted separately |
| Other operations | 480p draft; edit or extend from exactly one source video and a prompt |
A provider may still reject an unavailable input combination. Check the result card for its actual status and error.
What a five-second Seedance 2.5 clip costs
Credits for one five-second generation. The audio example also includes an image; the video example uses one five-second reference video. No batch or other reference media is included.
| Resolution | No references | With audio | With 5s video |
|---|---|---|---|
| 480p | 10 | 20 | 20 |
| 720p | 20 | 40 | 40 |
| 1080p | 45 | 90 | 100 |
A five-second 480p draft uses 10 credits. Requesting a five-second 720p final afterward uses another 20, for 30 credits across the two requests.
Longer clips, longer reference videos and multiple outputs change the total. Adding video and audio together applies the reference multiplier once. The live quote beside the Create button is the amount charged for your chosen settings.
Seedance pricing and plansCompare the same prompt on 2.0 and 2.5
Use a controlled test rather than treating the illustrative clips on this page as model output. The workspace keeps each result, its settings, credit cost and status together.
- 1
Hold inputs constant
Use the same text prompt, five-second duration and 720p output on both models. Leave references off and request one result per model.
- 2
Inspect both results
Play the resulting clips and check whether the subject, camera path and timing follow the prompt. Compare sound only if you enabled it on both runs.
- 3
Record what happened
Keep the prompt, model, settings, credits and any error with each clip. A new prompt or changed settings need a new comparison.
When a generation does not complete
The result card shows whether a request is still processing or has failed. These checks help locate the next useful action.
Still processing
A provider timeout can occur after it accepts a request. Check the existing result card for a callback or final status before starting another paid generation.
Confirmed failure
If the provider rejects or confirms that a job failed, the result shows Failed and the charged credits are returned. Read the error, change one input at a time and retry.
