How much does the Vidu Q3 API cost?

Vidu Q3 API pricing is per-second × resolution. Both viduq3-pro and viduq3-turbo bill at 540p / 720p / 1080p tiers — Turbo undercuts Pro at every tier. See current per-tier rates in the pricing table on this page. Audio and routing mode never change the Vidu Q3 API rate.

What is the difference between viduq3-pro and viduq3-turbo?

Both share the exact same parameter shape in the Vidu Q3 API. viduq3-pro renders at higher fidelity; viduq3-turbo cuts the per-second price roughly in half. A common pattern is to iterate on Turbo and re-render the keeper on Pro at the resolution you ship.

Can the Vidu Q3 API do image-to-video and first/last-frame in one call?

Yes. The Vidu Q3 API picks the mode from the count of image_urls you send: zero is text-to-video, one is image-to-video, two is first/last-frame. The aspect_ratio field only applies in text-to-video; sending it together with image_urls is rejected at the gateway with a clear 400.

What resolutions and durations does the Vidu Q3 API support?

The Vidu Q3 API supports 540p, 720p, and 1080p across both pro and turbo. Duration accepts any integer from 1 to 16 seconds (default 5). Pricing scales linearly with duration; resolution drives the per-second tier.

Does the Vidu Q3 API generate audio?

Yes. Audio defaults to on — every clip ships with dialogue, ambience, and sound effects already mixed in. Set audio to false in the Vidu Q3 API request body for a silent video. Audio does not change the per-second rate either way.

Where is the full Vidu Q3 API reference?

The full Vidu Q3 API parameter list, error codes, and runnable cURL examples live at /docs/viduq3.

Is Vidu Q3 API free or paid?

Paid. Completed generations are charged at the rates in this page's pricing table. Eligible new accounts may receive promotional test credits; availability and amount are shown at signup or in the dashboard. Technical or provider failures are refunded automatically, except where this page documents a charged output-moderation block.

Does Vidu Q3 API require a monthly subscription?

No. Pricing is pay-as-you-go: $1 buys 1,000 credits and credits never expire. Cost scales with what you generate rather than with a recurring fee.

How do I get a Vidu Q3 API key?

Sign up and create a key in the dashboard, no card required. Pass it as a Bearer token in the Authorization header.

Vidu Q3 API — Async Video Generation in One Endpoint

The Vidu Q3 API turns text or up to two images into a 1 to 16 second clip at 540p, 720p, or 1080p. One endpoint covers text-to-video, image-to-video, and first/last-frame transitions, audio built in.

What is the Vidu Q3 API?

Vidu Q3 is Vidu's async video generation model, offered on reAPI as two variants — viduq3-pro and viduq3-turbo — that share one endpoint and one parameter shape. The mode follows the number of images you send: none for text-to-video, one for image-to-video, two for a first/last-frame transition, with output running 1 to 16 seconds at 540p, 720p or 1080p and audio on by default. Billing is per second, at a rate set by variant and resolution.

What you can build with this model

Real-world workflows and production use cases you can build and ship with this model.

Animate a single still with the Vidu Q3 API

Pass one image and a motion prompt. The Vidu Q3 API returns a 1 to 16 second clip from the same endpoint as your text-to-video calls — no model swap, no extra integration. The aspect ratio of your output matches the source frame automatically.

Generate a clip

Smooth transitions between two frames with the Vidu Q3 API

Send two images and the Vidu Q3 API interpolates motion from the first frame to the last. Skip storyboarding and stitch keyframes directly into a finished shot — useful for transformations, day-to-night reveals, and product before/after spots.

Text-to-video with built-in audio via the Vidu Q3 API

Describe the scene, pick an aspect ratio, and the Vidu Q3 API returns a clip with dialogue and sound effects already mixed in. No timeline, no second TTS pipeline, no syncing pass on top of the render.

Why reAPI for Vidu Q3

One endpoint, three modes

The Vidu Q3 API picks its mode from the count of image_urls you send. Zero gives you text-to-video, one gives image-to-video, two gives first/last-frame interpolation — all on the same /api/v1/videos/generations call, with the same authentication and the same task polling pattern.

Pricing by resolution × seconds

The Vidu Q3 API charges per second and resolution only. Turbo undercuts Pro at every tier. See current 540p / 720p / 1080p rates in the pricing table on this page. Mode never shifts the rate, audio is included, and failed Vidu Q3 API jobs refund automatically.

Audio built into the Vidu Q3 API

Audio is on by default — dialogue, ambience, and effects ship inside the same MP4. Set audio to false in the Vidu Q3 API request body when you want a silent clip; the per-second rate stays the same either way.

Frequently asked questions

Common questions about this model.

The Vidu Q3 API is an async video generation endpoint with two variants — viduq3-pro and viduq3-turbo. One request body covers text-to-video, image-to-video, and first/last-frame interpolation; the Vidu Q3 API auto-routes the mode by how many images you attach.
