Vidu Q4 Image to Video with a five-tier quality ladder

Vidu Q4 animates exactly one starting image into a clip of 3 to 16 seconds, in five quality tiers from 540p to 4k, with optional sound.

Controls and specifications

This is the single-image product of the Vidu Q4 family on this platform: one starting picture, one clip. To use multiple reference pictures and audio clips, select Vidu Q4 Reference to Video in the workspace.

The five-tier ladder is what sets this model apart here. Drafts can run at 540p and a final render at 2k or 4k without changing tools, and the credit quote follows the tier and length you pick.

Upload one image, then set length, quality tier and sound. There is no shape selector, because the clip keeps the proportions of the image you uploaded. The prompt is optional here: a picture can be animated without a description.

What this model is good at

Five quality tiers

540p, 720p, 1080p, 2k and 4k are selectable per task, so a test shot and the final render can use different tiers.

Three to sixteen seconds

Any whole number of seconds between 3 and 16, chosen before you generate.

Sound you can switch off

A sound switch sits with the other controls: leave it on for a clip with atmosphere, or turn it off for a silent render.

Typical projects

Start with a draft

Test a picture at 540p, then repeat the same settings at a higher tier only for the image that worked.

Animating a hero still

Bring a product or scene picture to life while keeping its framing, because the clip inherits the image proportions.

Silent inserts

Turn sound off for clips that will sit under narration or music in the edit.

Limits to know before you start

  • Exactly one image per task, in JPEG, PNG or WebP and up to 50 MB. Multi-image reference input is not available on this product.
  • No shape selector: the output follows the uploaded image, so pick an image that already has the framing you want.
  • Quality tiers are settings, not measured sizes. In the files we checked, a 3-second request returned a 3.04-second clip and the pixel dimensions did not always match the tier label.
  • There is no reference audio input on this product; sound comes from the sound switch alone.

How to start

1

Open the workspace

Use a button on this page. It opens the right workspace with this model already selected, in the language you are reading now.

2

Describe the result

Write what should happen in the shot or image. Concrete subjects, framing and action give the model more to work with than short labels.

3

Set the controls and confirm

Choose length or quality tier, shape and sound where offered, then read the credit quote for those exact settings before you generate.

What it costs

Generation uses account credits. Cost depends on the model, quality and output size or duration. Reference images, video or audio may add charges in some modes. Check the workspace quote for your selected inputs and settings before generating; the pricing page lists credit packages.

Questions about this model

How many images can I use?

One. Vidu Q4 Image to Video animates a single starting picture; multi-image reference work belongs to the reference product.

Which quality tiers are available?

540p, 720p, 1080p, 2k and 4k. The credit quote changes with the tier and with the length you set.

Can I choose the output shape?

No. The clip keeps the proportions of the starting image, so there is no shape selector for this model.

Is a prompt required?

Not in image mode. You can animate a picture without writing anything, though a description of the motion gives the model more to work with.

Can I supply audio?

No. This product has a sound on/off switch but no audio input. Reference audio is offered on the reference product instead.
