Vidu Q3 Pro Start End To Video

Playground

Vidu Q3 Pro Start-End-to-Video creates smooth transitions between two keyframes with viduq3-pro (1–16s). Billing follows Vidu’s published Q3-pro per-second rates by resolution. Ready-to-use REST inference API on WaveSpeed.

Features

Vidu Q3 Pro Start-End-to-Video

Vidu Q3 Pro Start-End-to-Video generates videos with precise control over both the first and last frames. Provide a start image, an end image, and a text prompt, and the model creates a smooth, coherent transition between the two visual states. It supports multiple resolutions, motion control, and optional audio generation with background music.

Why Choose This?

• Start and end frame control Define both the opening and ending visuals for more precise and predictable video transitions.

• Smooth interpolation Generate natural, fluid motion between two reference frames.

• Fast pro-speed generation Q3 Pro is built for rapid iteration, testing, and content prototyping.

• Multiple resolution options Choose from 540p, 720p, or 1080p depending on your quality and budget needs.

• Optional audio generation Generate synchronized audio and optional background music for richer outputs.

• Motion intensity control Adjust movement_amplitude to control how subtle or dramatic the transition feels.

Parameters

How to Use

1. Upload your start image — provide the first frame of the video.
2. Upload your end image — provide the last frame of the video.
3. Write your prompt — describe the motion, action, and transition between the two frames.
4. Set duration — choose how long you want the video to be.
5. Set resolution — use 540p for speed, 720p for balance, or 1080p for quality.
6. Adjust motion (optional) — control movement intensity with movement_amplitude.
7. Enable audio (optional) — toggle generate_audio and bgm if you want sound in the result.
8. Submit — run the model and download your video.

Example Prompt

A cinematic transformation from a clean product photo to a glowing premium hero shot, with subtle camera push-in, soft reflections, and smooth visual motion between the two states.

Pricing

Pricing is based on duration and resolution.

Example Costs

Billing Rules

• Pricing scales linearly with duration
• Higher resolutions cost more per second
• movement_amplitude, generate_audio, bgm, and seed do not affect pricing
• Off-peak pricing may be available separately through the provider

Best Use Cases

• Scene transitions — Create smooth cinematic transitions between two visual states.
• Product morphing — Show product transformations, feature changes, or visual upgrades.
• Before/after content — Generate engaging videos that compare two different looks or conditions.
• Character animation — Animate a subject moving from one pose or mood to another.
• Rapid prototyping — Quickly test visual transition ideas with fast generation speed.

Pro Tips

• Use images with similar composition for smoother transitions.
• Describe the motion happening between the two frames, not just the static start and end states.
• Start with shorter durations like 5s to validate the transition before generating longer clips.
• Use a fixed seed when you want more consistent variations.
• Lower movement_amplitude for subtle transitions, and raise it for more dramatic changes.

Notes

• prompt, image, and last_image are all required.
• duration supports 1–16 seconds for Q3 Pro.
• seed = -1 means a random seed will be used.
• Native Vidu documentation uses the audio flag, while this WaveSpeed schema exposes generate_audio and bgm.
• Higher resolution increases both output quality and total cost.
