Vidu Q3 Start End Image To Video

Vidu Q3 Start-End-to-Video

Vidu Q3 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 — 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?

• 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.

• Motion control Adjust movement_amplitude to control the intensity of motion in the transition.

• Audio generation Optional synchronized audio and background music for complete video content.

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

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

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 — specify how long you want the video to be.
5. Set resolution — choose 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 for complete video with sound.
8. Run — submit and download your video.

Pricing

Resolution	Cost per Second
540p	$0.07
720p	$0.15
1080p	$0.16

Billing Rules

• Per-second billing based on duration and resolution
• Total cost = duration × per-second rate

Examples

• 5s @ 540p → 5 × $0.07 = $0.35
• 5s @ 720p → 5 × $0.15 = $0.75
• 5s @ 1080p → 5 × $0.16 = $0.80
• 10s @ 720p → 10 × $0.15 = $1.50

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.
• Time-Lapse Effects — Create artificial time-lapse videos with controlled start and end points.

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.
