What Is Vidu Q3?
Vidu Q3 is a next-generation AI video generation model like Gaga-1. It produces complete 16-second videos with synchronized audio, including character dialogue, environmental sound effects, and background music. This represents a significant advancement from previous models that generated silent video requiring separate audio production.
The model marks a transition from “motion generation” to “audio-visual generation” in AI video technology. Rather than producing isolated clips, Vidu Q3 creates cohesive narrative segments ready for commercial use.
Core Features of Vidu Q3
1. 16-Second Audio-Video Generation
Vidu Q3 produces videos up to 16 seconds with complete audio synchronization. This duration supports full narrative sequences including dialogue exchanges, scene establishment, and emotional resolution.
The audio system generates three synchronized elements:
- Character dialogue with accurate lip-sync
- Environmental sound effects based on scene context
- Background music matching the visual atmosphere
For example, a rainy urban street scene automatically includes ambient traffic sounds, rain acoustics, and appropriate atmospheric audio without manual specification.
2. Intelligent Camera Control
The model interprets cinematographic direction from text prompts. Users can specify shot sequences including:
- Establishing wide shots for scene context
- Medium shots for character interaction
- Close-ups for emotional emphasis
- Tracking shots following movement
The system also generates automatic shot transitions based on content understanding. A dialogue scene might begin with a two-shot, cut to close-ups during key lines, and return to a medium shot for resolution.
3. Multi-Language Text Rendering
Vidu Q3 renders text accurately within video frames in Chinese, English, and Japanese. This applies to:
- On-screen titles and captions
- Environmental signage
- Product labels and branding
- Artistic text effects
Previous AI video models struggled with text generation, often producing distorted or illegible characters. Q3 addresses this limitation for commercial applications requiring readable text.
4. Voice Language Support
Character dialogue generation supports Chinese, English, and Japanese with natural pronunciation and appropriate emotional delivery. Voice characteristics adapt to character appearance and scene context.
How to Use Vidu Q3: Step-by-Step Guide
Method 1: Text-to-Audio-Video
1. Access Vidu.com or the Vidu API at platform.vidu.com
2. Select the text-to-video option
3. Write a detailed prompt including:
- Scene description and setting
- Character actions and movements
- Dialogue with speaker attribution
- Desired camera movements and shot types
- Audio atmosphere notes
4. Generate and download the complete audio-video file
Method 2: Image-to-Audio-Video
1. Upload a reference image as the starting frame
2. Describe the desired action, dialogue, and audio elements
3. Specify camera movement if different from static
4. Generate the video with synchronized audio
Prompt Writing Best Practices
Effective prompts for Vidu Q3 include specific cinematographic language:
Shot Specification Example:
Shot 1: [Wide shot] Bamboo forest at dusk, two sword fighters face each other
Shot 2: [Close-up] Male fighter speaks: “Is there truly no possibility of reconciliation?”
Shot 3: [Reaction shot] Female fighter smirks coldly
Shot 4: [Action sequence] Combat begins with metallic clash sounds
This structure guides the model through shot transitions while maintaining narrative coherence.
Bonus: Gaga AI as a Strong Alternative AI Video Generator
For creators looking beyond a single, cinematic-focused model, Gaga AI offers a broader set of early-generation AI video capabilities powered by its core model, Gaga-1. Launched in October 2025, Gaga-1 predates newer models like Vidu Q3 and takes a more multimodal, creator-oriented approach to AI video generation.
Instead of prioritizing complex scene composition, Gaga AI focuses on video + voice generation, avatars, and expressive audiovisual output.

How Does Vidu Q3 Compare to Vidu Q2?
Vidu Q2 introduced multi-reference video generation, allowing users to maintain character and scene consistency across shots using multiple reference images. This feature remains a core strength of the Vidu platform.
Vidu Q3 builds on this foundation with three major additions:
| Feature | Vidu Q2 | Vidu Q3 |
| Maximum Duration | 8 seconds | 16 seconds |
| Audio Generation | Not included | Synchronized audio output |
| Camera Control | Basic | Intelligent shot switching |
| Text Rendering | Limited | Multi-language support |
| Reference Images | Up to 6 subjects | Enhanced consistency |
The Q2 multi-reference system excels at maintaining character appearance across different camera angles and scenes. Q3 enhances this with the ability to generate complete audio-visual sequences without post-production work.
Practical Applications for Vidu Q3
Short-Form Drama Production
The 16-second duration supports complete dramatic beats including setup, conflict, and resolution. Production teams can generate concept sequences and pre-visualization content without full shoots.
Advertising and Marketing
Product demonstrations with synchronized narration eliminate the need for separate voiceover recording. Consistent character appearance across multiple shots maintains brand identity.
Music Video Creation
Artists can generate performance footage from still images. The system matches lip movements to specified lyrics and generates appropriate instrumental accompaniment.
Social Media Content
Content creators can produce polished video segments quickly. The audio-visual completeness removes post-production bottlenecks.
Limitations and Considerations
Current limitations of Vidu Q3 include:
- Voice consistency across costume changes remains challenging
- Complex multi-character scenes may require multiple generations
- Regional dialects not currently supported
- Maximum 16-second duration per generation
For projects requiring extended duration, multiple generations can be combined with matching audio transitions.
