Open the studio at https://vidu-q4.com/dashboard/ai-video/home. Generating requires sign-in. Drafting a prompt on the homepage does not.

## Modes

The site offers two Vidu Q4 workflows:

- Image to video. One still is the start frame; the output keeps that frame's aspect ratio.
- Reference to video. Up to 12 reference images (characters, objects, scenes) plus up to 3 audio or voice references. References are cited in the prompt with @image-1 style tags.

There is no pure text-to-video entry in this studio - every generation needs at least one image.

## Output

- Length: 3-16 seconds
- Resolutions: 540p, 720p, 1080p, 2K, 4K
- Aspect ratios (reference mode): 16:9, 9:16, 1:1, 4:3, 3:4
- Audio: synchronized native sound, effects, and lip-matched speech; can be disabled
- Download format: MP4
