Vidu Q2 Pro Start End To Video Fast

Vidu Q2 Pro Start End To Video Fast

Playground

Vidu Q2 Pro Fast Start-End to Video generates smooth video transitions between start and end images with faster generation speed. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing.

Features

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

How to Use

1. Upload start image — provide the first frame of the transition.
2. Upload end image — provide the last frame of the transition.
3. Write your prompt — describe the motion and transition between frames.
4. Set duration — choose video length from 1 to 8 seconds.
5. Select resolution — 720p for faster processing, 1080p for higher quality.
6. Configure options (optional) — enable/disable BGM, adjust motion amplitude.
7. Run — submit and download your video.

Examples

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.
