Why Choose This?

Image-grounded generation Start from a reference photo for precise visual control over subject appearance, environment, and composition.
Start and end frame guidance Provide both a starting image and an end frame to define exactly where the clip begins and finishes.
Audio input support Upload an audio track to guide the rhythm, mood, and pacing of the generated video.
Negative prompt support Specify what you don't want in the video for more precise control over the output.
Prompt expansion Enable enable_prompt_expansion to let the model automatically enrich and optimize your prompt before generation.
Resolution options Generate at 720p or 1080p to match your delivery requirements.
Reproducible results Use the seed parameter to lock in a specific output for exact reproduction.

seed	No	Random seed for reproducible results. Use -1 for a random seed.

How to Use

Upload your image — provide the start frame to animate via URL or drag-and-drop.

Upload last image (optional) — provide an end frame to guide where the clip finishes.
Upload audio (optional) — provide an audio file or URL to synchronize the video.
Add negative prompt (optional) — specify elements you want to exclude from the output.
Select resolution — 720p for standard output, 1080p for higher-quality results.

Pro Tips

Use a high-quality, well-lit reference image with a clearly visible subject for the most natural animation.
Providing a last_image significantly improves motion direction and narrative coherence.
Use negative_prompt to avoid common artifacts like unwanted motion or blurry faces.
Enable prompt expansion for shorter or less detailed prompts to get richer output automatically.
Fix the seed once you find a result you like to iterate consistently across resolution and duration changes.

Notes

Both image and prompt are required fields; all other parameters are optional.
Ensure image and audio URLs are publicly accessible if using links rather than direct uploads.
Please ensure your content complies with usage policies.

Wan 2.7 Image To Video API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/alibaba/wan-2.7/image-to-video 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 Wan 2.7 Image To Video below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/alibaba/wan-2.7/image-to-video" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "audio": "https://example.com/your-audio.mp3",

    "resolution": "720p",
    "duration": 5,
    "enable_prompt_expansion": 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("alibaba/wan-2.7/image-to-video", {

Wan 2.7 Image To Video API — Frequently asked questions

What is the Wan 2.7 Image To Video API?

Wan 2.7 Image To Video is a Alibaba model for video generation from images, exposed as a REST API on WaveSpeedAI. WAN 2.7 converts images into videos (720p/1080p) with optional audio, supporting first and last frame control. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Wan 2.7 Image To Video 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/alibaba/alibaba-wan-2.7-image-to-video.

How much does Wan 2.7 Image To Video cost per run?

Wan 2.7 Image To Video starts at $0.50 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 Wan 2.7 Image To Video accept?

Key inputs: `prompt`, `image`, `audio`, `resolution`, `duration`, `seed`. 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/alibaba/alibaba-wan-2.7-image-to-video.

How do I get started with the Wan 2.7 Image To Video 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 Wan 2.7 Image To Video outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Alibaba). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
