Short drama clip generation: Create focused drama fragments from 8 to 12 seconds.
Script-driven control: Use content to describe the plot, action, dialogue, camera movement, and visual details for the clip.
Structured asset control: Define characters, scenes, and tools with IDs, names, types, reference images, and descriptions.
Reference positioning: Use image and placement to control positioning, panorama, or step-based references.
Precise duration selection: Choose a fixed duration of 8, 9, 10, 11, or 12 seconds.
Narrative workflow: Suitable for storyboard shots, scene-level clips, ads, hooks, and short character-driven video moments.

Q3 Drama Clip API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/vidu/q3/drama-clip with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read URLs from data.outputs. Examples for Q3 Drama Clip below.

HTTP example

# Submit the prediction
curl --fail-with-body --connect-timeout 10 --max-time 60 \
  -X POST "https://api.wavespeed.ai/api/v3/vidu/q3/drama-clip" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "placement": "panorama",
    "duration": 8,
    "resolution": "1080p",
    "aspect_ratio": "9:16"
}'

# Wait at least 2 seconds, then poll. Safe GET requests may be retried.
curl --fail-with-body --connect-timeout 10 --max-time 30 \
  --retry 4 --retry-all-errors --retry-delay 1 \
  -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# Start at 2 seconds and increase the interval for long-running tasks.
# Stop on completed, failed, cancelled, or timeout.

Node.js example

// npm install wavespeed
const { Client } = require('wavespeed');

const apiKey = process.env.WAVESPEED_API_KEY;
if (!apiKey) throw new Error('Set WAVESPEED_API_KEY');
const client = new Client(apiKey);

try {
  const result = await client.run("vidu/q3/drama-clip", {
        "placement": "panorama",
        "duration": 8,
        "resolution": "1080p",
        "aspect_ratio": "9:16"
}, {
    timeout: 3600,
    pollInterval: 2.0,
  });
  console.log(result.outputs);
} catch (error) {
  console.error('Generation failed:', error);
  process.exitCode = 1;
}

Python example

# pip install wavespeed
import os
from wavespeed import Client

client = Client(api_key=os.environ["WAVESPEED_API_KEY"])

try:
    output = client.run(
        "vidu/q3/drama-clip",
        {
    "placement": "panorama",

except Exception as error:
    raise SystemExit(f"Generation failed: {error}") from error

Q3 Drama Clip API — Frequently asked questions

What is the Q3 Drama Clip API?

Q3 Drama Clip is a Vidu model for video generation from images, exposed as a REST API on WaveSpeedAI. Vidu Q3 Drama Clip generates 8-12 second script-driven drama videos from structured assets, including characters, scenes, and tools. It is ideal for compact story scenes, storyboard shots, and focused narrative moments. 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 Drama Clip 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 result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/vidu/vidu-q3-drama-clip.

How much does Q3 Drama Clip cost per run?

Q3 Drama Clip starts at $1.12 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 Drama Clip accept?

Key inputs: `image`, `aspect_ratio`, `resolution`, `duration`, `assets`, `content`. 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-drama-clip.

How do I get started with the Q3 Drama Clip 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 Q3 Drama Clip 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.
