Vidu Q2-Pro Start-End-to-Video

Vidu Q2-Pro Start-End-to-Video is a professional-grade AI video generation model that creates smooth, cinematic transitions between two images. Provide a start frame and an end frame — the model generates a high-quality video that naturally bridges the two visuals with fluid motion up to 1080p resolution, ideal for demanding creative and production workflows.

Why Choose This?

• Precise frame control Define exactly where the video begins and ends for complete narrative control.

• Professional quality Cinematic-grade transitions with smooth, coherent motion at up to 1080p.

• Flexible duration Create videos up to 10 seconds in length.

• Audio generation Optional synchronized audio and background music.

• Motion control Adjust movement amplitude for subtle or dramatic transitions.

• Prompt Enhancer Built-in tool to automatically improve your transition descriptions.

Parameters

How to Use

1. Upload your start image — provide the image representing the first frame of the video.
2. Upload your end image — provide the image representing the last frame of the video.
3. Write your prompt — describe the transition, motion, and how the scene evolves between frames.
4. Set resolution — higher resolution for better quality, lower for faster processing.
5. Adjust duration — set video length up to 10 seconds.
6. Configure audio (optional) — enable/disable audio generation and background music.
7. Set motion intensity (optional) — control how dynamic the transition is.
8. Run — submit and download your video.

Best Use Cases

Pro Tips

• Use the Prompt Enhancer to refine your transition descriptions.
• Ensure start and end images share a compatible composition for the most coherent transition.
• Be specific in your prompt about how the motion or transformation should unfold between the two frames.
• Keep subject framing consistent between start and end images for the smoothest interpolation.
• Use movement_amplitude to control the energy of the transition — "small" for elegant morphs, "large" for dramatic reveals.
• Use longer durations for complex transformations that require more time to unfold naturally.

Notes

• All three fields — prompt, start_image, and end_image — are required.
• Maximum video duration is 10 seconds.
• The model interpolates motion and scene content between the two provided frames.
• Audio generation adds synchronized sound effects and ambient audio.
