Vidu Q3 Start End Image To Video | High-Quality Motion-Diverse Video Generation

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

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	$0.07
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.
