Keeps Your Original Aspect Ratio
The output follows the shape of the image you upload, so a vertical product shot stays vertical and a widescreen still stays wide. You don't have to re-crop for each platform or lose the edges of your composition.
Vidu Q4 AI Video Generator: Keep Characters and Voices Consistent
Vidu Q4 Preview is ShengShu's newest AI video model. It turns one image, or up to 15 reference images and 3 voice clips, into videos of up to 16 seconds with native audio and 2K/4K output.

Vidu AI Image to Video with Vidu Q4
Start from a single image. Describe the motion and the camera, and Vidu Q4 extends the still into a 3–16 second clip at 2K or 4K. Used as an image animator, it keeps the look of the frame you upload and lets the prompt decide what happens next.
Fast Action That Holds Together
Martial arts, running and fight scenes are where image-to-video clips tend to warp. Vidu says Q4 keeps this kind of motion fluid, with fewer deformations, stutters and artifacts. Name the action and its direction in the prompt to give the model a clear path.
Effects with Real Weight
Explosions, smoke, particles and energy effects render with more natural light and movement. That matters for game trailers, fantasy shorts and product reveals, where one burst of VFX carries the whole shot.
Prompts That Keep the Shot on Track
A common complaint about Vidu image to video is a clip that drifts away from the brief. Q4 follows camera moves and transitions more closely, but the prompt still steers: one subject, one main action and one camera move per shot gives the most predictable result.
Reference to Video AI: Up to 15 Images and 3 Voices
Reference to video is where Q4 changes the most. Instead of one starting frame, you hand the model a set of references: faces, outfits, props, locations and a style frame. Up to 15 images and up to 3 voice clips go into a single generation, and Vidu Q4 builds the scene around them.
Lock the Cast Before You Generate
Upload each character, costume and prop the way a crew preps a set. With 15 slots, up from 7 in the Q3 reference models, a two-person scene can carry front and side views of both characters, plus the location and a style reference.
Tell the Model Who Is Who
When two references disagree on a face or a costume, the prompt decides. Point to each reference by its tag and say what it does in the shot, for example: "@1 in the white gi punches while @2 holds guard." Clear tags cut the guesswork that leads to mixed-up faces.
Give Each Character a Voice
Add up to three voice clips, each 3–12 seconds long, to clone your characters' voices. The clips set how a character sounds; the dialogue itself goes into the prompt, assigned to whoever says it.
Images and Voices Only
Vidu reference to video in Q4 accepts still images and audio. It does not take a reference video for motion or editing, so if you need to copy movement from existing footage, use a model that supports video reference.
Image to Video with Audio: Voice, Lip Sync and Sound Together
Q4 generates sound with the picture. Dialogue and ambient sound come out in the same pass, so you aren't exporting a silent clip and patching audio in afterwards.
Native Vidu Lip Sync
Lip movement is generated together with the voice and the face, rather than pasted onto a finished clip. Expressions and mouth shapes stay tied to what the character is actually saying.
The Same Voice, Shot After Shot
With earlier models, one character could sound different every time you generated. Voice references tie the voice to a sample you choose, so a series character keeps one voice from episode to episode.
Write the Lines in the Prompt
Put dialogue in quotation marks and name who says it. Keep each line short enough to fit the clip: 16 seconds is the ceiling, and shorter lines leave room for a reaction shot.
What You Can Make with Vidu Q4
Vidu built Q4 for four kinds of work: AI series, advertising, social content and cinematic production. Here is how each one uses the Vidu AI video generator.
AI Series and Short Drama
Recurring characters need the same face and voice in every episode. Reference images and voice clips make that practical across a full run of short episodes.
Ad Concepts and Product Variants
Test several creative directions for a pitch, or make versions of one product spot for different markets, without rebuilding the cast each time.
Social Videos
Vertical clips for Reels, Shorts and TikTok, with dialogue and sound already built in.
Previs and Cinematic Shorts
Block out performance, framing and pacing before a shoot. 4K output with 10-bit color holds up when footage goes through color grading.

Two things stay the same. The 16-second ceiling matches Vidu Q3, and Q4 has no text-to-video mode, which Q3 Pro still offers. If you need either, see our Vidu Q3 page.
On the Artificial Analysis image-to-video leaderboard, Vidu Q4 Preview debuted at #3, while Vidu Q3 Pro sits at #19 on the same board (as of Oct 8, 2026).
