What is Vidu Q3?

Vidu Q3 is Shengshu's flagship multimodal AI video model. It accepts text, images, multi-reference subjects, and audio as input — and generates clips with synced sound, complex cinematic language, and narrative continuity. Built for creators, ad teams, and short-form storytellers who need more than a moving image.

Vidu Q3 Key Features

Five capabilities that make Vidu Q3 the strongest narrative AI video model.

Reference-to-Video

Upload up to 7 reference images — character, product, scene — and Vidu Q3 will preserve their identity across the entire generated clip.

Synchronized Audio

Native audio generation alongside visuals. Footsteps, ambient sound, dialogue, and music are produced together — no separate sound design pass needed.

Cinematic Narrative Depth

Vidu Q3 understands narrative arcs and complex camera language. Single generations carry a setup → action → resolution beat instead of one flat motion.

Adjustable Motion Amplitude

Dial motion intensity from subtle drifts to high-energy action. Critical for matching the pacing of ads vs. cinematic spots.

Customizable Style & Resolution

Pick aspect ratio, duration, resolution, and style references. Vidu Q3 honors all four together, so output matches your creative direction precisely.

How to Use Vidu Q3

From a blank canvas to a finished narrative clip in three steps.

Step 01
Pick your starting point
Type a prompt, upload reference images of characters or scenes, or combine both. Vidu Q3's reference-to-video flow is its strongest mode.
Step 02
Direct sound and motion
Describe what should be heard (dialogue, ambient, music) and what should be seen (camera movement, action, mood). Set motion amplitude for pacing.
Step 03
Generate & iterate
Pick aspect ratio (16:9 / 9:16 / 1:1 / 3:4 / 4:3), duration (3–16s), and resolution (720p / 1080p). Generate, refine, run side-by-side variants.

Vidu Q3 Prompting Tips

Best structure: subject + sound + camera + scene + style. Vidu Q3 takes audio direction seriously, so include what you want to hear (footsteps on gravel, distant thunder, a soft cello). For reference-to-video, upload clean, well-lit images and describe the relationship between them (e.g., "the woman in image 1 walks past the storefront in image 2"). Use motion amplitude words — drift, walk, run, sprint — to control energy. Combine with cinematic mood words (documentary, dreamlike, music video) for tighter style.

Frequently Asked Questions

Vidu Q3 leads on synced audio and narrative continuity. While Sora 2 focuses on visual fidelity and Kling on motion control, Vidu pairs visuals and sound natively — so a single generation already feels like a directed shot.

Yes — it's the model's strongest mode. Upload up to 7 reference images of characters, products, or scenes; Vidu Q3 preserves visual identity across the whole clip.

Yes. Shengshu allows commercial use of Vidu output, including the generated audio. Avoid copyrighted music styles or real-person voices — refer to the provider's terms.

Aspect ratios: 16:9, 9:16, 1:1, 3:4, 4:3. Resolutions: 720p and 1080p. Duration 3–16 seconds per clip.

Usually 60–150 seconds depending on duration and resolution. 1080p with synced audio takes longer than 720p without.

Yes — every Zopia account gets starter credits to try Vidu Q3 with no commitment.

Yes. Both Chinese and English work natively. Audio output handles dialogue in both languages.
