Seedance 2.0 Fast supports generating high-definition video clips of 4-15 seconds with exceptional quality.
Yes, the Seedance 2.0 Fast API supports image-to-video generation, allowing you to upload reference images to control the style and content of the output video.
Depending on network and system load, the Seedance 2.0 Fast API typically generates a high-quality video within 30-120 seconds per request.
Seedance 2.0 Fast supports multiple resolutions and aspect ratios including 16:9, 9:16, and 1:1, making it suitable for various platforms such as YouTube, TikTok, and Instagram. Supported output resolutions: 480p / 720p.

Seedance 2.0 keeps the core workflows of Seedance 1.5 Pro—text-to-video, image-to-video, and first/last frame control—and adds audio-driven generation, video reference, and motion control. In the version comparison on this page, average generation time also drops from about 60 seconds to about 45 seconds.
Both seedance-2.0-fast and seedance-2.0-mini output 480p or 720p video, while the standard seedance-2.0 model also offers 1080p and 4K.

You can access ByteDance Seedance 2.0 Fast directly through the Seedance API on APIMart: create an account, generate an API key, and send requests with the model ID seedance-2.0-fast. If your code comes from a platform that names the model bytedance/seedance-2.0, switch the model field to seedance-2.0-fast and check the APIMart docs for parameters; generation runs as an asynchronous task that you poll for the result.
Sign up for APIMart, open the API Keys page in your dashboard and create a key. The same key calls the ByteDance Seedance 2.0 Fast API and every other model on the platform, with pay-as-you-go billing and no subscription.
Send a generation request with your prompt and parameters. The Seedance 2.0 Fast API runs as an asynchronous task: it returns a task id right away, and you poll that task until the result is ready. Full parameters and code examples are in the APIMart docs (docs.apimart.ai).
