Step by step
How to use Vidu Q4 in 6 steps
- 1
Open Vidu Q4 in the Studio
Open the Studio (it opens with Vidu Q4 selected), or choose the Video tab and pick Vidu Q4 in the model menu. Sign in with Google or your email; you pay per generation from prepaid credits.
- 2
Choose what to make
- Image → Video — a first frame and a prompt. Add it under “First frame”.
- Reference → Video — up to 15 images and 3 audio clips, and a prompt.
In reference mode, refer to each upload in the prompt by its tag — @Image1 and @Audio1 — and say what to take from it.
- 3
Write the prompt
One shot per prompt works best. Cover these, in plain sentences:
- Subject. Who or what is on screen, with the details that must stay consistent: age, clothing, materials, colours.
- Action. One clear action in the present tense. For clips up to 16 s, describe a short sequence of beats.
- Camera. Shot size and movement: close-up, wide, dolly-in, orbit, handheld, drone.
- Scene and light. Location, time of day, and where the light comes from.
- Style. Lens, film look, colour grade or animation style.
- Sound. Vidu Q4 generates synchronized audio with the clip, so name the ambience, effects or lines of dialogue you want.

The exact price is shown before you run: press Generate (or ⌘/Ctrl + Enter). The amount is held from your balance and refunded in full if the generation fails.

Download and iterate
Results appear above the prompt; download them from there. Change one thing per try — the prompt, the camera move or a setting — so you know what helped. Compare runs the same prompt on several models side by side, and Code shows the same request for the API.

Common Vidu Q4 mistakes
Drafting at 4K
Every try at 4K costs 8.7× one at 540p. Settle the composition and motion at 540p, then render the keeper at the resolution you deliver.
Expecting one long take
One generation is up to 16 seconds (3–16 s). Plan longer pieces as several shots, and keep the subject consistent with the same reference images in each.
Several actions in one prompt
Give each clip one clear action and one camera move. A list of events in one prompt usually gets merged or skipped.
References the prompt doesn't name
Refer to each upload by its tag — @Image1, @Video1, @Audio1 — and say what to take from it (the face, the outfit, the camera move, the voice).
Describing what you don't want
Prompts work better when they describe what should be on screen. "No blur" or "no extra fingers" can pull the result towards the very thing you name.
