Seedance V1 Lite I2V 1080P | Fast Image-to-Video API

Seedance V1 Lite — Image-to-Video 1080p

Seedance V1 Lite Image-to-Video 1080p is Full HD image-to-video generation model that transforms static images into stunning 1080p videos. With optional last-frame control, flexible durations up to 12 seconds, and multiple aspect ratios, create cinematic animations from any image.

Why It Stands Out

Full HD 1080p output: Generate high-resolution videos with exceptional clarity.
First and last frame control: Optionally specify an ending image for precise animation control.
Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
Flexible duration: Generate videos from 2 to 12 seconds long.
Multiple aspect ratios: Wide range from ultrawide 21:9 to vertical 9:16.
Camera control: Option to fix camera position for stable shots.
Reproducibility: Use the seed parameter to recreate exact results.

Pro Tips for Best Quality

Use high-resolution, well-lit source images for optimal results.
Use last_image for controlled transitions between two specific frames.
Enable camera_fixed for professional-looking static shots.
Choose 21:9 for cinematic content, 9:16 for mobile-first platforms.
Start with shorter durations to test concepts, then extend for final versions.

Notes

Ensure uploaded image URLs are publicly accessible.
Processing time varies based on duration and current queue load.
Please ensure your prompts comply with content guidelines.

Seedance v1 Lite I2v 1080p API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seedance-v1-lite-i2v-1080p 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 Lite I2v 1080p below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/bytedance/seedance-v1-lite-i2v-1080p" \
  -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-lite-i2v-1080p", {
        "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-lite-i2v-1080p",
    {
    "image": "https://example.com/your-input.jpg",
    "prompt": "A cinematic shot of a city at sunset, soft golden light",

Seedance v1 Lite I2v 1080p API — Frequently asked questions

What is the Seedance v1 Lite I2v 1080p API?

Seedance v1 Lite I2v 1080p is a ByteDance model for video generation from images, exposed as a REST API on WaveSpeedAI. Seedance Lite creates coherent multi-shot image-to-video clips in 1080p with smooth, stable motion and accurate prompt following. 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 Lite I2v 1080p 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-lite-i2v-1080p.

How much does Seedance v1 Lite I2v 1080p cost per run?

Seedance v1 Lite I2v 1080p starts at $0.45 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 Lite I2v 1080p 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-lite-i2v-1080p.

How long does Seedance v1 Lite I2v 1080p take to generate?

Average end-to-end generation time on WaveSpeedAI is around 161 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 Lite I2v 1080p 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.
