Seedance 2.5 Controls Available in Clipin

The generator follows the current official Replicate Seedance 2.5 schema and updates the credit estimate from duration, resolution, and whether a video reference is included.

01

Text and Multimodal Inputs

The Seedance 2.5 video generator can start from a prompt or a first frame, or combine up to 30 reference images, 10 video URLs, and 10 audio URLs. Reference audio requires at least one reference image or video.

02

Native 4–30 Second Output

Choose any explicit Seedance 2.5 duration from 4 through 30 seconds so the credit estimate and task reservation match the requested output length.

03

Synchronized Native Audio

Seedance 2.5 generates dialogue, lip movement, sound effects, and background music together with the visuals. Put spoken dialogue in double quotes inside the prompt.

04

480p and 720p Resolution

Choose Seedance 2.5 at 480p for lower-cost exploration or 720p for more detail. The estimate changes before submission so the selected provider tier is visible.

05

Seven Aspect-Ratio Options

Create landscape, square, portrait, or ultrawide outputs, or choose adaptive so Seedance 2.5 can determine the best ratio from the supplied media.

06

Credit-Aware Provider Pricing

Credits use Replicate's current per-second Seedance 2.5 rates and Clipin's standard $0.003 provider cost per credit, rounded once to a 5-credit increment. Video-reference inputs use the higher video-input tier.
