It edits existing videos with cinematic multi-shot quality, AI camera control, consistent characters, 480P / 720P / 1080P / 4K output, 4-15s duration, and flexible aspect ratios. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Seedance 2.0 Mini Video Edit API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header.

How much does Seedance 2.0 Mini Video Edit cost per run?

Seedance 2.0 Mini Video Edit starts at $0.75 per run.

The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Seedance 2.0 Mini Video Edit accept?

Key inputs: `prompt`, `video`, `aspect_ratio`, `resolution`, `reference_images`, `enable_web_search`.
