Vidu Q2 Pro Fast Start-End to Video
Vidu Q2 Pro Fast Start-End to Video generates smooth video transitions between a start frame and an end frame. This model combines the visual quality of Q2 Pro with faster generation speeds, perfect for scene transitions and visual storytelling.
Why Choose This?
-
Fast generation Significantly faster than Q2 Pro while maintaining high quality.
-
Bi-frame guidance Uses both start and end frames to anchor identity, layout, and lighting.
-
Temporal continuity Minimizes flicker and maintains subject integrity across frames.
-
Object-aware motion Preserves faces, hands, and fine details while animating.
-
Camera-path estimation Simulates subtle pans, dolly moves, and push-ins.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the video motion (max 2000 chars) |
| image | Yes | Start frame image (URL or upload) |
| last_image | Yes | End frame image (URL or upload) |
| duration | No | Video length: 1-8 seconds (default: 5) |
| resolution | No | Output resolution: 720p (default), 1080p |
| bgm | No | Add background music (default: enabled) |
| movement_amplitude | No | Motion intensity: auto (default), small, medium, large |
| seed | No | Random seed for reproducibility (-1 for random) |
How to Use
- Upload start image — provide the first frame of the transition.
- Upload end image — provide the last frame of the transition.
- Write your prompt — describe the motion and transition between frames.
- Set duration — choose video length from 1 to 8 seconds.
- Select resolution — 720p for faster processing, 1080p for higher quality.
- Configure options (optional) — enable/disable BGM, adjust motion amplitude.
- Run — submit and download your video.

Best Use Cases
- Scene Transitions — Seamless bridges between shots in long-form content.
- Before/After Sequences — Demonstrate change-over-time with smooth motion.
- Film Previsualization — Explore transitions and camera moves early.
- Storyboard Animation — Bring static boards to life between key beats.
- Time-lapse Effects — Create smooth temporal transitions between two states.
Pro Tips
- Ensure start and end frames have similar aspect ratios for best results.
- Use clear prompts describing the motion between frames.
- For big pose or layout jumps, consider shorter durations for smoother transitions.
- Set movement_amplitude to "small" for subtle, professional transitions.
- Use a specific seed to reproduce the same result across runs.
- Enable BGM to add fitting background music automatically.
Notes
- Prompt, image, and last_image are all required fields.
- Maximum video duration is 8 seconds.
- Start and end frames should share similar visual characteristics for best continuity.
- Ensure uploaded image URLs are publicly accessible.
- Seed value -1 generates a random seed each time.
