How much does the Vidu Q3 API cost?

Vidu Q3 API pricing is per-second × resolution. viduq3-pro charges $0.056 / $0.12 / $0.128 per second at 540p, 720p, and 1080p. viduq3-turbo charges $0.032 / $0.048 / $0.056 per second at the same tiers. 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.

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 you can build

Real workflows powered by this model.

01/case

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

02/case

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.

03/case

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.

05why

Why reAPI

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. viduq3-pro starts at $0.056 per second at 540p; viduq3-turbo starts at $0.032 per second. 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.

07faq

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.
