Balloon Flyaway | Trending Video Effects API

Balloon Flyaway Effect

Requirements

Number of Images

Mandatory
Only supports uploading one image

Number of People

Supports single-subject, dual-subject, and multi-subject in realistic style characters and animals

Image Requirements

When the person/animal in the photo is a single subject and fully visible, the effect is better

Prompt

Mandatory
The format should remain largely unchanged, for details please refer to the "prompt" parameter in the request example
If there are personalized requirements, the prompt words can be modified without altering the structure and majority of the content

Effect Boundaries

When the number of subjects in the photo is three or more, or the subjects are close to each other, there may be missing subjects when they turn into balloons and fly away

Best Practices

Use clear, well-lit photos
Ensure all subjects are fully visible
Maintain appropriate spacing between subjects
Keep the default prompt structure
Avoid complex backgrounds
Use photos with good contrast between subjects and background

Balloon Flyaway API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/video-effects/balloon-flyaway 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 Balloon Flyaway below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/video-effects/balloon-flyaway" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "image": "https://example.com/your-input.jpg"
}'

# 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("video-effects/balloon-flyaway", {
        "image": "https://example.com/your-input.jpg"
});

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

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "video-effects/balloon-flyaway",
    {
    "image": "https://example.com/your-input.jpg"
}
)

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

Balloon Flyaway API — Frequently asked questions

What is the Balloon Flyaway API?

Balloon Flyaway is a Video Effects model for AI inference, exposed as a REST API on WaveSpeedAI. Transform photos into playful balloon flyaway videos with an image-to-video effect that makes subjects float away with charming motion. 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 Balloon Flyaway 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/video-effects/video-effects-balloon-flyaway.

How much does Balloon Flyaway cost per run?

Balloon Flyaway starts at $0.20 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 Balloon Flyaway accept?

Key inputs: `image`. 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/video-effects/video-effects-balloon-flyaway.

How long does Balloon Flyaway take to generate?

Average end-to-end generation time on WaveSpeedAI is around 454 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Balloon Flyaway outputs commercially?

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