ExamplesView all
The man throws a baseball — camera locks onto the spinning ball in an extreme close-up tracking shot as it flies through a downtown canyon of skyscrapers at high speed. Motion blur on buildings. The ball arcs upward, passes through clouds, then descends and punches through a cottage window with a shattering glass explosion. Reverse angle: inside a warm English study, an oversized ginger cat wearing a fluffy white bathrobe reclines on a vintage armchair, candy wrappers everywhere. The ball rolls to a stop at his paw. The cat glances down at it, completely unimpressed, then resumes eating a chocolate bar. Fireplace crackles. Slow zoom into the cat's judging face. Comedy, photorealistic, dramatic contrast between action and absurd calm.

What is the Seedance 2.0 Fast Image To Video Turbo API?
Seedance 2.0 Fast Image To Video Turbo is a ByteDance model for video generation from images, exposed as a REST API on WaveSpeedAI. Seedance 2.0 Fast (Image-to-Video Turbo) generates cinematic 720p/1080p videos from reference images using speed-optimized inference —the fastest and most affordable Seedance image-to-video option with native audio-visual synchronization and director-level control. You can call it programmatically or try it from the playground above.
How do I call the Seedance 2.0 Fast Image To Video Turbo 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. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedance-2.0-fast-image-to-video-turbo.
How much does Seedance 2.0 Fast Image To Video Turbo cost per run?
Seedance 2.0 Fast Image To Video Turbo starts at $0.60 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. 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 Fast Image To Video Turbo accept?
Key inputs: `prompt`, `image`, `aspect_ratio`, `resolution`, `duration`, `enable_web_search`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedance-2.0-fast-image-to-video-turbo.
How do I get started with the Seedance 2.0 Fast Image To Video Turbo API?
Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.
Can I use Seedance 2.0 Fast Image To Video Turbo outputs commercially?
Commercial usage rights depend on the model's license, set by its provider (ByteDance). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
