Vidu Q4 AI Video Generator

Vidu Q4 is Shengshu Technology’s current flagship video model. Q4 Preview launched on October 7, 2026. It turns one image, or a stack of references, into a clip of up to 16 seconds, with sound generated in the same pass, at up to 4K. The limits below are from Vidu’s model map and API docs.

01 — Capabilities

A still, or a stack of references — not a blank prompt

Q4 Preview is documented as image-to-video and reference-to-video. Text-to-video is on older Vidu lines, not on this model id.

01
Up to 16 seconds, at 24 fps
Image-to-video accepts 3 to 16 seconds, default 5. Reference-to-video accepts 1 to 16 seconds. The model map lists 24 fps. There is no 30-second mode on Q4 Preview.
02
540p through 4K
The documented resolutions are 540p, 720p, 1080p, 2K and 4K. 720p is the default. Image-to-video keeps the aspect of the input still; there is no separate aspect-ratio field on that route.
03
Fifteen images and three voices
Reference-to-video takes 1–15 images for character, scene and style, plus up to 3 voice references. Image-to-video takes exactly one still as the first frame.
04
Audio is generated with the picture
Image-to-video defaults audio to on. Reference-to-video needs audio set to true. You can ask for all sound, speech only, or effects only. Dialogue and effects come out in the same generation.

02 — Prompt to output

Prompts that match the clips above

Each prompt describes the picture on its card. “Use this prompt” sends that text to Create. The generator on this page runs Seedance 2.5, not Vidu Q4.

01 · Portrait
PromptClose-up of a young man with curly hair in a grey knit sweater, soft window light. He glances away, then smiles. Slow push-in, shallow depth of field.
02 · Product
PromptA white leather sneaker on a pale grey studio backdrop, soft diffused light. The camera orbits slowly. Stitching stays sharp, the look stays minimal.
03 · Street
PromptA slow dolly down a cobblestone lane in an old European village. Climbing roses on stone walls, café tables in morning sun, a few people walking in the distance.
04 · Character
PromptA young woman with shoulder-length brown hair in an olive t-shirt, late-afternoon gold light. She turns her head and looks off. Breeze in her hair, a handheld feel.

03 — Where it fits

Jobs that start from a still or a reference pack

Q4 Preview is built around a picture you already have, plus optional voices. A text-only idea has to go through an older Vidu model, or through another generator.

A character that has to keep the same face and voice
Up to 15 stills and 3 voice clips can pin appearance and speech. That is the case Vidu’s Q4 page is explicit about: series work, ads, one take with the same person.
Animate one frame, keep its ratio
Image-to-video uses the still as the first frame and keeps that aspect. 3–16 seconds, up to 4K. There is no 16:9 field to override a square upload.
A line of dialogue already in the clip
Native audio can be speech, effects or both. Eight to sixteen seconds is enough for one spoken beat with the mouth generated together. It is not a full scene of conversation.
4K for a finish, 720p while you draft
Default resolution is 720p. 2K and 4K are listed, and they cost more. The press note also mentions 10-bit color; treat that as a launch claim, not an API field you set.

04 — Verdict

05 — Side by side

Vidu Q4, Veo 3.1 and Kling 4.0

Entry method, length and how many references you can stack are where these three stop lining up. Vidu Q4 numbers are from the October 2026 Preview docs.

06 — How it works

Start a clip on ImgToVid

Step 1
Describe one shot
Subject, action, camera. If you wanted Vidu’s 15-image stack, say who has to stay consistent in the prompt. Vidu Q4 will not be the model that runs it.
Step 2
Use the generator on this page
It runs Seedance 2.5, because Vidu Q4 is not offered here. The prompt and the settings carry into Create.
Step 3
Generate in Create
Membership and credits are checked there. Coming back to this page does not switch the model over to Vidu Q4.
