About Vidu Q2 Pro Fast

Vidu Q2 Pro Fast is a speed-tuned Q2 Pro variant from Shengshu that turns a single image or a pair of frames into a short video at 720p or 1080p. It has no 540p tier and takes no text-only or reference input. It is meant for generating several motion options around one prepared composition during an iterative session.

Where it works well

Output is limited to 720p and 1080p, so even quick drafts are at a size usable for review.
Image-to-video and start-end frames cover both single-still animation and controlled transitions.
It is built for repeated runs, letting you compare several movements for the same starting picture.
Short clip lengths in whole-second steps make it simple to test timing.

When to choose another model

Text-to-video and reference-to-video are not offered, so you need a prepared image.
No 540p option exists, so there is no lowest-cost draft size.
Clips are silent, since synchronized audio belongs to the Q3 models.

Start/end-frame generation does not expose the native audio selector available to Q3; image audio support is operation-specific.

Use TokenLab create endpoint and follow returned poll_url; if you need a fixed status path, use `/v1/tasks/{id}`.

Durations from 1 to 8 seconds are accepted.

Motion options for one frame
Run the same still with different movement prompts and choose the take that fits the edit.
Iterating on a transition
Adjust the last frame and re-render to check how the bridge between two compositions looks.
Fast client previews
Show moving versions of approved stills to a client within a single working session, instead of waiting for a long render queue between rounds.
Social teaser variants
Produce several short cuts of the same hero image for A/B testing.

Prompt examples

FAQ

What is Vidu Q2 Pro Fast?

It is a faster variant of Vidu Q2 Pro that takes an image, or first and last frames, and returns a short video at 720p or 1080p.

How does it differ from Q2 Pro?

Q2 Pro also offers reference-to-video and a 540p tier. Pro Fast narrows to image and frame-pair inputs at 720p and 1080p, aimed at faster iteration.

Can I write a prompt without an image?

No. It supports image-to-video and start-end-to-video only, so a source image is required. Use Vidu Q2 or a Q3 model if you want to start from a text description.

Which clip lengths are available?

Whole-second durations from one to eight seconds are offered, which makes it simple to test timing and compare how long each movement needs to play out.

Does it generate audio?

Vidu's model map ties synchronized audio and video output to the Q3 series. Expect silent video from this Q2-family variant, and add music or sound effects separately in your editor.

How much does Vidu Q2 Pro Fast cost?

Rates depend on the billing unit, specification, and usage. Compare matching conditions in the model's detailed pricing; a single rate does not determine the total cost.
