ByteDance · Model and API
Seedance is ByteDance’s video model family. The official Seedance 2.5 announcement introduces clips up to 30 seconds and multimodal references. Choose a version available in runblob and build your scene here.
Start with one action and a clear camera movement. For a product clip, prepare a product reference and describe the setting and lighting. For several events, define their order: what appears first, what changes and how the scene ends.
Your selected version determines resolutions, duration and reference limits. Face, Mini and Official are variant labels in our catalog. Check the settings and calculated cost before generation; features in the official service can differ from those exposed here.
To integrate the Seedance API, select the exact version and settings in the playground. The generated cURL includes the endpoint, request fields and required Bearer authorization type. Move the request into your server code; keep secret keys out of the browser. References use service-accessible URLs rather than local file paths.
Seedance API pricing depends on version, resolution and duration. For per-second rates, compare the cost of the full clip. Video-reference variants can include additional input seconds in billing; the calculator shows billable time before generation.
Compare Seedance 2.0 and 2.5 using a specific scene and matching output settings. Runblob’s Mini, Face and Official variants have their own controls: the shared family name does not imply identical reference limits or prices. Select a specific version for integration.

Test composition and movement before filming
The reference sneaker rests on wet asphalt. The camera slowly moves a quarter circle around it, with night lights reflected in the background. Preserve sole shape and colors in one continuous shot.
The product reference establishes appearance; text specifies motion and lighting.
The character from the image walks toward a window, stops and watches the rain. Static camera, soft daylight and a calm pace. Preserve clothing and hairstyle.
Related actions are easier to review than a collection of unrelated locations.
Preserve the reference mountain lake composition. A light breeze creates ripples as clouds move slowly. Very gentle camera push-in, with no new objects entering the frame.
Subtle motion is useful for testing stability of the starting composition.
Runblob prices in USD. The final cost depends on the selected version and request parameters. Public rates refresh every six hours; personal rates are available in your dashboard.
Configure the parameters and build an API request. Sign in to runblob to start a generation.
Select a version, resolution and duration in the playground. Rates come from the current runblob catalog, so check the estimate before starting.
Use an image with a clear main subject and describe the desired action. Add more references when you can explain the role of each one.
