Vidu AI Video Generator: Put Your Photos in One Scene with Vidu Q4 Preview and Q3 Pro




What is Vidu AI?
Vidu AI is the video model line from ShengShu Technology, a Beijing company with roots in Tsinghua University research. Vidu is known for keeping several separate subjects recognizable in one scene, something ShengShu calls multiple-entity consistency, and for generating sound with the video. The generator above has two versions: Vidu Q4 Preview, which works only from pictures and can combine up to 15 reference photos, and Vidu Q3 Pro, which can start from a written prompt or from a start frame with an optional end frame. Both versions make clips up to 16 seconds.

How to use Vidu on Plimo
Pick a Vidu version
The generator above opens on a Vidu model. Use the version cards to switch between them: Q4 Preview when you have pictures to work from, Q3 Pro when you want to begin with words.Add your pictures
For Q4 Preview, drop one photo into the start frame, or switch to reference mode and add up to 15 photos of the people, pets and places that belong in the scene. Q3 Pro takes a start frame with an optional end frame, or no image at all.Tell Vidu what happens
A single start frame can go without a prompt. Reference photos need a sentence that explains how they come together, such as “the dog leaps into the woman's arms on the beach”, and a text-only clip on Q3 Pro needs the whole scene written out.Choose length, resolution and sound
Set the duration and resolution. Sound starts on, and turning it off doesn't lower the price shown on the Generate button.Generate and review
Press Generate once the credit figure looks right. The clip shows up in My creations, where Remake reloads your photos and prompt for another attempt.
Why use Vidu on Plimo
Room for 15 reference photos
Q4 Preview accepts more reference images than any other video model in Plimo's menu, so separate portraits of a whole friend group can share one scene.From 540p up to 4K
Q4 Preview runs from 540p through 1080p to 2K and 4K, so a clip can begin as a low-cost test and finish sharp enough for a big screen.Sound at no extra cost
Both versions can add audio to the clip, and the price is the same with it on or off, so you only decide whether you want it.Free credits to get started
Vidu is a member model, but every new account gets free credits once, which you can spend on Seedance 2.0 Mini or Grok Imagine 1.5 video to try Plimo first.Clean clips you can use for work
Vidu videos made with a membership download without a watermark, may be used commercially and stay in your account longer.
Vidu compared with other video models
Kling
Kling 4.0 runs to 30 seconds and can edit an uploaded clip, while Vidu stops at 16 seconds but Q4 Preview takes up to 15 reference photos to Kling's 7.
Veo
Veo 3.1 Fast gives a fixed 8-second shot with a cinematic look, whereas Vidu lets you set the length and switch the sound off.
Seedance
Seedance accepts short reference clips alongside photos and can be tried on free credits through its 2.0 Mini, while Vidu guides the scene with pictures only.
Hailuo AI
Hailuo AI's MiniMax H3 Max aims at realistic faces with sound in every clip, and takes start and end frames or up to nine photos plus three clips.
Grok Imagine
Grok Imagine 1.5 begins at a 6-second clip with built-in sound and can be tried on free credits, and the Grok Imagine series also makes still images.
Wan
Wan 3.0 stretches from 2 to 30 seconds and can follow reference clips as well as up to ten photos.
FLUX
FLUX 3 Video lets you check a rough draft before the full render and runs up to 20 seconds, working from frames rather than reference photos.
SkyReels
SkyReels V4 can end on a chosen frame even without a start frame, which Q4 Preview can't, and it always needs a written prompt.
HappyHorse
HappyHorse 1.1 works much like Q4 Preview, from a start frame or a set of reference photos, but caps references at nine and needs a prompt every time.
What people make with Vidu
A group shot nobody was in together
Add a separate portrait of each friend, up to fifteen, and describe everyone crowding around one birthday cake as the candles go out. Q4 Preview is built to keep each face recognizable.You, your dog and your favorite café
Use reference photos of a jacket, your dog and a café interior, then ask for you walking in wearing the jacket with the dog trotting at your heels.Then and now in one shot
On Q3 Pro, set a childhood photo as the start frame and a recent one as the end frame. The clip travels from one to the other in a single move.A scene from words alone
Q3 Pro can work without any image. Describe a paper lantern rising over a night market and drifting past lit rooftops, and add the sound of the crowd below.A portrait that comes alive
Put a portrait into the Q4 Preview start frame, leave the prompt empty and see what motion it chooses.A product in a styled setting
Give Q4 Preview a product photo, a model shot and a backdrop, then describe the model lifting the item off a shelf. Made during a membership, the result can go on your shop page.One long take with no cuts
Write a single continuous shot on Q3 Pro, like a cyclist weaving through a morning market from one end to the other, and let it run the full 16 seconds.
