Q3 Text To Video API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/vidu/q3/text-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 Q3 Text To Video below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/vidu/q3/text-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",
    "style": "general",
    "resolution": "720p",
    "duration": 5,
    "aspect_ratio": "4:3",
    "movement_amplitude": "auto",
    "generate_audio": true,
    "bgm": true,
    "seed": 0
}'

# 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("vidu/q3/text-to-video", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "style": "general",
        "resolution": "720p",
        "duration": 5,
        "aspect_ratio": "4:3",
        "movement_amplitude": "auto",
        "generate_audio": true,
        "bgm": true,
        "seed": 0
});

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

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "vidu/q3/text-to-video",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "style": "general",
    "resolution": "720p",
    "duration": 5,
    "aspect_ratio": "4:3",
    "movement_amplitude": "auto",
    "generate_audio": true,
    "bgm": true,
    "seed": 0
}
)

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

Q3 Text To Video API — Frequently asked questions

What is the Q3 Text To Video API?

Q3 Text To Video is a Vidu model for video generation, exposed as a REST API on WaveSpeedAI. Vidu Q3 Text-to-Video turns text prompts into high-quality videos with exceptional visual fidelity and diverse 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 Q3 Text 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/vidu/vidu-q3-text-to-video.

How much does Q3 Text To Video cost per run?

Q3 Text To Video starts at $0.35 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 Q3 Text To Video accept?

Key inputs: `prompt`, `aspect_ratio`, `resolution`, `duration`, `seed`, `bgm`. 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/vidu/vidu-q3-text-to-video.

How long does Q3 Text To Video take to generate?

Average end-to-end generation time on WaveSpeedAI is around 510 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Q3 Text To Video outputs commercially?

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