Create Complete Story Beats with Vidu Q3
Last verified: July 30, 2026
Vidu Q3 generates dialogue, environmental effects, music, and picture together, helping creators produce synchronized narrative clips without assembling sound afterward. Created by ShengShu AI, the Q3 series entered Vidu's developer platform on January 27, 2026, and is built for story-led video production; it also powers the consumer-facing Vidu Claw marketing agent.
Official documentation positions Pro around audiovisual synchronization and shot segmentation, Turbo around faster generation, and the reference model around intelligent camera switching with consistency across viewpoints. The family advances beyond Q2 with a longer developer-documented clip ceiling, smart scene cuts, multi-speaker conversations, and spoken output in English, Japanese, or Chinese.

Prepare the Scene Before You Generate
Use these checks to prevent rushed pacing, confused speakers, drifting references, and avoidable framing errors.
Choose the right Q3 tier
Select Pro when final-detail quality matters most, or Turbo when you need faster iterations before committing to a polished take.
Match the source mode
Use text for scenes built from scratch, image mode for a single visual anchor, first-to-last-frame for a planned transition, or reference mode for recurring subjects.
Write sound into the action
Name each speaker, include their exact lines, and describe ambience and effects where they occur so the soundtrack follows the visual beat.
Keep one achievable story arc
Define a clear opening state, central action, and finishing image instead of packing unrelated events into the selected clip length.
Curate reference roles
Give each reference a distinct purpose such as character, prop, costume, or location, and remove conflicting designs that could blur identity.
Lock framing and seed
Choose the delivery ratio before composing the shot, then preserve the seed when testing controlled changes to dialogue, motion, or camera direction.
Choose Native Sound or HDR Finishing
The Q3 column reflects controls available on this page; where “Q3 lab ceiling” appears, it points to a wider creator-documented range that is not selectable here. The competitor column covers the base Ray 3 model rather than later numbered updates.
| Feature/Spec | Vidu Q3 | Ray 3 |
|---|---|---|
| Generation routes | Text-to-video, image-to-video, first-to-last-frame, and reference-to-video | Text-to-video, image-to-video, and start/end Keyframes |
| Single-generation duration | 4–16 seconds ; Q3 lab ceiling: 1–16 seconds for text, image, and first/last-frame generation, or 3–16 seconds for reference generation | SDR text-to-video: 10 seconds; SDR image-to-video: 5 seconds; HDR text-to-video: 5 seconds |
| Native output resolution | 540p, 720p, 1080p | 540p, 720p, 1080p |
| Sound created with picture | Available on audio-enabled page variants for synchronized dialogue and effects | No native audio |
| Selectable frame shapes | 1:1, 3:4, 4:3, 9:16, 16:9 | 1:1, 3:4, 4:3, 9:16, 16:9, 21:9 |
| Opening and closing frame control | Dedicated first-to-last-frame mode on Pro and Turbo variants | Start frame, end frame, or both through Keyframes |
| Reference-led identity | 1–7 JPG, JPEG, PNG, or WebP images, up to 10 MB each ; Q3 lab ceiling permits source assets up to 50 MB, with a 20 MB Base64 request-body cap | Character Reference supported across text, image, video, and Reference workflows |
| Switch between story-sound and grading paths | Use the Q3 story workflow directly on Vidofy.ai | Ray 3 is also usable on Vidofy.ai in the same model workspace |
Match the Model to the Production Bottleneck
Build sound into the story beat
If spoken lines, ambience, and effects must shape the timing from the first render, the Q3 family removes a separate sound-design handoff. Base Ray 3 officially generates silent video, making it a picture-first source when audio will be produced later.
Plan the finishing pipeline
Ray 3's strongest documented differentiator is native HDR in 10-, 12-, and 16-bit EXR using the ACES2065-1 color space, giving post-production teams additional grading and exposure latitude. Vidu's Q3 materials instead emphasize synchronized storytelling, smart cuts, and reference consistency; the reviewed documentation does not describe an equivalent HDR or EXR path.
Choose the Path That Matches Your Finish
Use this quick guidance to pick the best option for your workflow.
When to choose each: Choose the Q3 family for dialogue-led shorts, anime or drama scenes, narrative advertising, and multi-reference continuity where sound and picture should emerge together. Choose Ray 3 for silent cinematic shots that prioritize reasoning-led motion and an HDR/EXR grading pipeline.
Generate a Finished Story Clip in Four Steps
Move from route selection to a saved result in four focused steps.
Step 1: Choose the route and tier
Select text, image, first-to-last-frame, or reference generation, then choose Pro for finish quality or Turbo for faster iteration.
Step 2: Build the audiovisual brief
Describe the subject, action, camera, lighting, dialogue, ambience, and effects, or add the source assets required by the selected route.
Step 3: Set the deliverable
Choose clip length, resolution, aspect ratio, audio behavior, and seed so the output matches its intended channel and revision plan.
Step 4: Generate and refine
Review pacing, lip movement, identity, and transitions, then reuse the seed while making focused prompt changes before saving the preferred clip.
Frequently Asked Questions
What is Vidu Q3 best at for AI video creation?
Its signature strength is producing story-led video with native sound in the same generation, so dialogue, effects, music, and visuals can share one timeline. Official materials also emphasize multi-speaker scenes, detailed camera pacing, smart cuts, anime, short drama, and narrative advertising.
Can I create a 16-second video with synchronized dialogue and effects?
Yes. This page offers selectable durations from 4 to 16 seconds, and audio-enabled variants can create dialogue and effects with the picture. Vidu's official materials also document direct audiovisual output and a 16-second generation ceiling.
Can I use seven reference images in reference-to-video mode?
Yes. You can add 1–7 JPG, JPEG, PNG, or WebP files here, with each file limited to 10 MB. The Q3 lab ceiling permits image assets up to 50 MB in Vidu's reference documentation, although Base64 request bodies have a separate 20 MB cap that is not the limit used by this form.
Should I choose Q3 Pro or Q3 Turbo for video generation?
Choose Pro when the page's ultra-quality or premium finish tier matters more than speed. Choose Turbo when faster generation and high-quality output are better suited to exploration, testing, or producing multiple directions.
Which languages can spoken video use?
Official product materials list English, Japanese, and Chinese video output. Write each speaker's dialogue in the intended language, identify who delivers every line, and keep language changes unambiguous.
Can I download a clean clip without a watermark?
Free accounts receive watermarked outputs, while paid plans generate without a watermark. Confirm the account level before producing a client-facing or final distribution copy.
Can I use the generated videos in client work or paid campaigns?
Usage rights depend on the terms that apply to your account, inputs, and distribution channel. Review those terms before commercial release, confirm that you have permission for every uploaded asset, and do not treat watermark removal as a license grant; this is not legal advice.
How should I troubleshoot weak motion or missed instructions?
Reduce the scene to one primary action, name every speaker, state camera movement explicitly, and place sound cues where they occur. Reuse the seed for controlled revisions, try the prompt helper for clearer structure, or move from Turbo to Pro when finish quality matters more than iteration speed.
How are generation credits calculated here?
The per-generation credit amount is calculated live from the selected model and options, so a fixed price is not quoted in the page content. New accounts receive 60 signup credits that can be applied while testing available settings.
