What Is Vidu Q4?

Vidu Q4 turns a visual idea into a short video workflow. Start with a still image when the composition already exists, or use reference mode to describe a scene and guide it with optional pictures. In either case, a useful prompt focuses on what moves and how the camera sees it.

The version described here is Vidu Q4 Preview. This is an independent service, with two modes rather than a separate tool for every type of input. Read how to use Vidu Q4 for the individual controls, upload steps, and ways to prepare a clear first prompt.

Vidu Q4 Preview Features

Choose the mode that matches your starting material. References provide guidance; they do not guarantee identical subjects or perfect motion in every frame.

Vidu Q4 Image to Video

Use one image to establish the subject, lighting, and composition. Describe a small movement first: a slow camera push, drifting clouds, or a gentle turn. A narrow motion goal makes it easier to judge the result.

Vidu Q4 Reference to Video

Write a required prompt and add relevant reference pictures when you need visual guidance. Explain which subject or setting matters, then describe the action. You can also work from the prompt alone without adding images.

  3. Select resolution, duration, and the controls available in that mode.

Vidu Q4 FAQ

Use your own or authorized material and review each output before sharing it. Read the terms of service for account and content rules.

What input do I need for Vidu Q4?▼

Image to Video requires one picture in PNG, JPG, JPEG, or WebP format. Reference to Video requires a written prompt; pictures and audio references are optional. Choose material you have permission to use and keep each uploaded file within 100MB.

Can I use reference mode without images?▼

Yes. Write a prompt describing the subject, setting, and movement, then leave the reference image list empty. You are still using Reference to Video. Add pictures when visual guidance is useful, rather than uploading unrelated images just to fill the list.

Which video sizes and lengths can I choose?▼

Both modes offer 540p, 720p, 1080p, 2K, and 4K, with whole-number durations from 3 to 16 seconds. The starting settings are 720p and 5 seconds. Higher settings are available options, rather than a guarantee of a successful or flawless result.

What does prompt expansion do?▼

In Image to Video, prompt expansion lets the model elaborate on your description. Leave it on for a simple direction, or turn it off when you want to try a more specific prompt. This switch is separate from Generate audio and is not present in reference mode.

How are video credits calculated?▼

Vidu Q4 uses a per-second credit rate for the selected resolution, multiplied by the video length. Both modes use the same rates. Review the estimate before submitting and choose a shorter clip when you want to explore an idea with fewer credits.
