In a wide shot, a young white man skateboards in an outdoor skatepark. He has short black hair and wears a white T-shirt, black pants, and black-and-white sneakers. Arms outstretched and head down, he leans into a boardslide maneuver along the edge. Ramps and rails surround him, with trees and scattered people in the background. The sky is vivid blue with a few clouds. The camera tracks him as he glides rightward, then leaps into a spinning trick—rotating twice midair before landing and skating onward.
A group of people riding horses down the street, followed by a tracking shot.
A girl plays the piano, captured through multiple cinematic angle cuts.
A gentle breeze stirs the flowers, fountain droplets fall, and sunlight refracts through a wine bottle, creating glowing flares.
In a static shot, a man from the right side of the frame walks toward another man on the left and expresses strong dissatisfaction.
A girl smiles charmingly by the seaside.
Two men walking forward.
A statue covers its face and begins to weep as surrounding hands gradually retreat.
A cat jumps onto the table and begins to drink water.
The camera slowly rotates as the sleeves gently flutter.
Seedance v1 Lite I2V 480p generates short videos from a single reference image plus a motion-focused prompt. Upload a starting image, describe the action and camera beats, and the model animates the scene while keeping the input image as the visual anchor. You can also provide an optional last_image to guide how the clip ends, and enable camera_fixed when you want motion without camera movement.

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seedance-v1-lite-i2v-480p with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Seedance v1 Lite I2v 480p below.

time.sleep(2)Seedance v1 Lite I2v 480p is a ByteDance model for video generation from images, exposed as a REST API on WaveSpeedAI. Seedance V1 Lite is a 480p Image-to-Video model for coherent multi-shot videos with smooth motion and precise prompts. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
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 result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedance-v1-lite-i2v-480p.
Seedance v1 Lite I2v 480p starts at $0.080 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.
Key inputs: `prompt`, `image`, `aspect_ratio`, `duration`, `seed`, `camera_fixed`. 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-v1-lite-i2v-480p.
Median end-to-end generation time on WaveSpeedAI is around 63 seconds per request, based on recent successful runs. Queue time varies with global demand; live status is visible in the prediction record.
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.
