How to Use

Write your prompt — describe the scene, action, camera feel, and visual style you want.
Choose a style — select a preset that matches your creative direction.
Set resolution — use 540p for speed, 720p for balance, or 1080p for higher quality.
Set duration — choose the desired video length.
Adjust motion (optional) — control movement intensity with movement_amplitude.
Configure audio (optional) — toggle generate_audio and bgm if you want sound in the output.
Set a seed (optional) — use a fixed seed for more reproducible generations.
Submit — run the model and download the generated video.

Example Prompt

A cinematic night drive through a neon-lit city, light rain reflecting on the road, smooth forward camera motion, moody atmosphere, realistic lighting, subtle environmental motion

Pricing

Pricing is based on duration and resolution.

Resolution	Cost per Second
540p	$0.05
720p	$0.125
1080p	$0.15

Example Costs

Resolution	1s	5s	10s	16s
540p	$0.05	$0.25	$0.50	$0.80
720p	$0.125	$0.625	$1.25	$2.00
1080p	$0.15	$0.75	$1.50	$2.40

Billing Rules

Pricing scales linearly with duration
540p costs $0.25 per 5 seconds
720p costs 2.5× the 540p base rate
1080p costs 3× the 540p base rate
style, movement_amplitude, generate_audio, bgm, and seed do not affect pricing
Off-peak pricing may be available separately through the provider

Best Use Cases

Social media content — Create engaging short-form videos for Reels, Shorts, and similar formats.
Rapid prototyping — Quickly visualize creative concepts before committing to production.
Marketing and ads — Generate promotional clips with synchronized audio and motion.
Storytelling — Bring narrative scenes to life with motion, mood, and background music.
Game and app assets — Create animated content for interactive experiences and presentations.

Pro Tips

Be specific in your prompt about scene, action, lighting, and camera movement.
Start with 540p for rapid iteration, then switch to 720p or 1080p for final-quality output.
Use a fixed seed when you want more consistent variations.
Enable bgm for atmospheric content, and disable it when you plan to add custom audio later.
Lower movement_amplitude for calmer scenes, and raise it for more energetic or dramatic motion.

Notes

prompt is the only required field.
duration supports 1–16 seconds for Q3 Pro.
Higher resolution increases both output quality and total cost.
Native Vidu documentation uses the audio flag, while this WaveSpeed schema exposes generate_audio and bgm.
seed = -1 means a random seed will be used.

Q3 Pro Text To Video API — Quick start

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

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/vidu/q3-pro/text-to-video" \
  -H "Content-Type: application/json" \

Q3 Pro Text To Video API — Frequently asked questions

What is the Q3 Pro Text To Video API?

Q3 Pro Text To Video is a Vidu model for video generation, exposed as a REST API on WaveSpeedAI. Vidu Q3 Pro Text to Video is a fast AI video generation model that creates high-quality, audio-capable videos from text prompts with support for 1–16 second outputs. Ready-to-use REST inference API for cinematic clips, advertising creatives, social media videos, product visuals, storytelling, and professional text-to-video workflows with simple integration, no coldstarts, and affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Q3 Pro 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-pro-text-to-video.

How much does Q3 Pro Text To Video cost per run?

Q3 Pro Text To Video starts at $0.25 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 Pro Text To Video accept?

Key inputs: `prompt`, `resolution`, `duration`, `seed`, `bgm`, `generate_audio`. 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-pro-text-to-video.

How do I get started with the Q3 Pro Text 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 Q3 Pro 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.
