Why Vidu Q3 Pro?
thumb_upStrengths
- Industry-leading 16-second single-pass generation -- longest among all major video models
- Native audio-video generation in one pass: dialogue, SFX, and background music without post-production
- Competitive API pricing starting at $0.07/sec on FAL.ai for 540p
- Available on three major API providers: FAL.ai, WaveSpeed, and Replicate
- Strong cinematic camera language comprehension with intelligent scene transitions
infoLimitations
- Standard Q3 limited to 1080p -- 4K requires Q3 Pro tier
- No video-to-video or motion brush capabilities
- Not self-deployable (closed source, no model weights)
- 24fps only, no higher frame rate options
- Complex multi-character scenes can produce identity drift over longer durations
auto_fix_highPrompt Guide
- 1Think like a director -- define subject, action, environment, and camera angle explicitly. Vidu Q3 is strongest when prompts read like short shot descriptions.
- 2Start with 5 seconds at 720p to learn how the model responds, then scale up to longer durations and higher resolutions for final output.
- 3Avoid overcomplexity -- most low-quality outputs come from stacking too many actions and camera moves in too little time. Keep each shot focused on one primary action.
- 4Describe lighting explicitly with terms like 'golden hour sunlight', 'soft studio lighting', or 'harsh midday glare' to control the visual mood.
- 5Specify audio intentionally -- indicate who speaks and when, include tone labels like 'calm narrator voice', or state 'no narration' for product shots.
- 6Use image-to-video as a visual anchor -- provide a start frame so the model does not have to guess subject details, and focus the prompt purely on motion and change.
✓ Do this
- Structure prompts as: Subject + Action + Environment + Camera + Audio cues
- Use cinematic camera language: dolly zoom, tracking shot, crane shot, shallow depth of field, anamorphic bokeh
- For native audio, specify pace, tone, and gender neutrality: 'calm, mid-tempo, neutral voice'
- Leverage the 16-second max duration for narrative sequences with beginning, middle, and end
- Ensure camera movements have physical motivation -- motion looks real when it has a reason within the scene
✗ Avoid this
- Maximum 1080p resolution -- Q3 Pro tier supports up to 4K but standard Q3 caps at 1080p
- Very fast multi-character scenes in short durations may produce identity inconsistency
- Text rendering in generated video is not reliably supported
- No video-to-video mode -- only text-to-video and image-to-video inputs
- Audio quality degrades with overly complex or overlapping sound descriptions
Example Prompts
“A lone fisherman casts his line into a misty lake at dawn. Camera slowly dollies forward from behind, revealing the vast still water. Birds chirp softly, the line splashes gently. Morning fog drifts across the surface.”
“Close-up of a pianist's hands moving across ivory keys in a dimly lit concert hall. [Pianist, intense but restrained]: Classical piano melody fills the hall. Camera holds steady, shallow depth of field, warm amber spotlight.”
“Aerial drone shot sweeping over a neon-lit Tokyo street at night. Rain-slicked roads reflect colorful signs. Camera tilts down as pedestrians with umbrellas cross below. Ambient city sounds: traffic, distant chatter, rain.”
