ExamplesView all

Tail flick slow-motion, cut to POV shot through window of sparrows taking flight, ending with resigned yawn

Slow-mo raindrops dripping from eaves to dog’s nose shake, thunder rumble vibrating collar tag in macro

Beak smoothing wing transitions to cage door opening, bird hopping onto finger stretching wings in silhouette

Gentle belly rub hand motion, cut to slow rise stretch with creaky joints sound, hobbling to water bowl

Slow dolly along banquet table, cherub’s wing malfunction sparks igniting grapevine fire, transition to Baroque smoke curling into new constellations

A girl sits on a rooftop under a full moon, fairy lights strung around her glowing gently in the dark. She writes slowly in a journal, pausing now and then to gaze at the stars. Everything moves slowly—like a quiet dream suspended between sleep and memory.

Seedance v1 Pro I2v 720p API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seedance-v1-pro-i2v-720p with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Seedance v1 Pro I2v 720p below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/bytedance/seedance-v1-pro-i2v-720p" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "image": "https://example.com/your-input.jpg",
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "duration": 5,
    "aspect_ratio": "21:9",
    "camera_fixed": false,
    "seed": -1
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("bytedance/seedance-v1-pro-i2v-720p", {
        "image": "https://example.com/your-input.jpg",
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "duration": 5,
        "aspect_ratio": "21:9",
        "camera_fixed": false,
        "seed": -1
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "bytedance/seedance-v1-pro-i2v-720p",
    {
    "image": "https://example.com/your-input.jpg",
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "duration": 5,
    "aspect_ratio": "21:9",
    "camera_fixed": false,
    "seed": -1
}
)

print(output["outputs"][0])  # → URL of the generated output

Seedance v1 Pro I2v 720p API — Frequently asked questions

What is the Seedance v1 Pro I2v 720p API?

Seedance v1 Pro I2v 720p is a ByteDance model for video generation from images, exposed as a REST API on WaveSpeedAI. Seedance V1 Pro creates coherent multi-shot image-to-video clips with smooth, stable motion and faithful prompt adherence. 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 v1 Pro I2v 720p 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-v1-pro-i2v-720p.

How much does Seedance v1 Pro I2v 720p cost per run?

Seedance v1 Pro I2v 720p starts at $0.30 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 v1 Pro I2v 720p accept?

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-pro-i2v-720p.

How long does Seedance v1 Pro I2v 720p take to generate?

Average end-to-end generation time on WaveSpeedAI is around 89 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Seedance v1 Pro I2v 720p 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.
