Features
Vidu Q3 Turbo Start-End-to-Video
Vidu Q3 Turbo Start-End-to-Video generates videos with precise control over both the first and last frames, powered by fast turbo-speed generation. Provide a start image, an end image, and a text prompt — the model creates a smooth, coherent video transition between the two states. Supports multiple resolutions, motion control, and optional audio generation with background music.
Why Choose This?
-
Fast generation Turbo architecture delivers quick results for rapid prototyping and iteration.
-
Start and end frame control Define both the beginning and ending visuals for precise, predictable video transitions.
-
Smooth interpolation AI-powered motion generates natural, fluid movement between your two reference frames.
-
Multiple resolutions Choose from 540p, 720p, or 1080p to balance quality and cost.
-
Audio generation Optional synchronized audio and background music for complete video content.
-
Motion control Adjust movement_amplitude to control the intensity of motion in the transition.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the desired motion and action |
| image | Yes | Start frame image (URL or upload) |
| last_image | Yes | End frame image (URL or upload) |
| duration | No | Video length in seconds (default: 5) |
| resolution | No | Output resolution: 540p, 720p, or 1080p (default: 720p) |
| bgm | No | Include background music (default: enabled) |
| generate_audio | No | Whether to generate synchronized audio (default: enabled) |
| movement_amplitude | No | Motion intensity: auto or manual value (default: auto) |
| seed | No | Random seed for reproducible results (default: -1) |
How to Use
- Upload your start image — provide the first frame of the video.
- Upload your end image — provide the last frame of the video.
- Write your prompt — describe the motion, action, and transition between the two frames.
- Set duration — specify how long you want the video to be.
- Set resolution — choose 540p for speed, 720p for balance, or 1080p for quality.
- Adjust motion (optional) — control movement intensity with movement_amplitude.
- Enable audio (optional) — toggle generate_audio and bgm for complete video with sound.
- Run — submit and download your video.
Pricing
| Resolution | Cost per Second |
|---|---|
| 540p | $0.04 |
| 720p | $0.06 |
| 1080p | $0.08 |
Billing Rules
- Per-second billing based on duration and resolution
- Total cost = duration × per-second rate
Examples
- 5s @ 540p → 5 × $0.04 = $0.20
- 5s @ 720p → 5 × $0.06 = $0.30
- 5s @ 1080p → 5 × $0.08 = $0.40
- 10s @ 720p → 10 × $0.06 = $0.60
Best Use Cases
- Scene Transitions — Create smooth cinematic transitions between two visual states.
- Product Morphing — Show product transformations, color changes, or feature variations.
- Before/After Content — Generate engaging videos showing transformations or comparisons.
- Character Animation — Animate a character moving from one pose to another.
- Rapid Prototyping — Quickly test transition concepts with turbo-speed generation.
Pro Tips
- Use images with similar composition for smoother transitions.
- The prompt should describe the motion and action happening between frames, not just the static scenes.
- Start with shorter durations (5s) to test transitions before generating longer clips.
- Set a seed value to reproduce the same result or create consistent variations.
- Lower movement_amplitude for subtle transitions, higher for dramatic transformations.
Notes
- Prompt, image, and last_image are all required fields.
- Higher resolution increases both quality and cost.
- Audio generation (generate_audio and bgm) is included at no extra cost.
- Seed value of -1 means random seed.
