Introducing Vidu Q3 Start End To Video on WaveSpeedAI

Introducing Vidu Q3 Start-End to Video on WaveSpeedAI

The most advanced start-end frame video model from Shengshu Technology has arrived. We’re thrilled to announce the availability of Vidu Q3 Start-End to Video on WaveSpeedAI—bringing the power of the globally top-ranked Vidu Q3 generation to precise, dual-keyframe video creation.

Vidu Q3 made waves when it launched on January 30, 2026, ranking No. 1 in China and No. 2 globally on Artificial Analysis benchmarks. Now, with the Start-End to Video variant, creators can harness that same industry-leading quality while maintaining full control over both the opening and closing frames of their generated videos. Provide a start image, an end image, and a text prompt—and watch the model produce smooth, cinematic transitions between the two states at up to 1080p resolution.

What is Vidu Q3 Start-End to Video?

Vidu Q3 Start-End to Video is a dual-keyframe interpolation model that generates high-quality videos by intelligently bridging two reference frames. Unlike standard image-to-video models that extrapolate unpredictably from a single image, this model anchors both the beginning and end of your video, then synthesizes the natural motion path between them.

The underlying Vidu Q3 architecture represents a generational leap over Q2. Built on Shengshu Technology’s advanced vision transformer foundation, Q3 delivers improved visual fidelity, better motion coherence, and superior physical logic—independent testing gives it a 7.5/10 physics score, with objects interacting realistically and character movements appearing natural and weighted. Frame-level distortions are significantly reduced compared to earlier generations, and motion continuity is noticeably smoother.

What makes the Start-End variant especially powerful is predictability. Traditional AI video generation produces beautiful but uncontrollable results. By constraining both endpoints, creators can direct the narrative arc of their video with precision while still benefiting from Q3’s cinematic motion engine and natural interpolation.

Key Features

Q3-Generation Visual Quality Vidu Q3 produces clearer imagery with fewer artifacts than any previous Vidu model. The improvements in architecture and data augmentation reduce flicker and improve motion continuity, delivering output that looks intentional rather than algorithmically generated.

Dual-Frame Precision Control Define both your starting and ending visuals. The model preserves identity, lighting, composition, and spatial relationships across the entire clip, ensuring your subject remains consistent from first frame to last.

Smooth, Physics-Aware Interpolation The AI-powered motion engine generates natural, fluid movement between your two reference frames. Objects obey realistic physics, characters move with weight and intention, and camera transitions feel cinematically crafted.

Multiple Resolution Options Choose from 540p, 720p, or 1080p output to balance quality against cost. Whether you’re prototyping ideas at lower resolution or producing final deliverables at full HD, the model adapts to your workflow.

Motion Amplitude Control Fine-tune the intensity of motion in your transitions. Use subtle movement for gentle transformations or crank it up for dramatic morphs and action sequences.

Native Audio Generation A standout capability inherited from the Q3 architecture: optional synchronized audio and background music generation at no extra cost. Your videos can ship complete with sound design, eliminating the need for separate audio production.

Built-In Prompt Enhancer The integrated prompt enhancement tool automatically improves your scene descriptions, helping you get better results without needing to master complex prompting techniques.

Real-World Use Cases

Cinematic Scene Transitions

Create smooth transitions between two visual states for films, commercials, and music videos. Feed in your opening shot and closing shot, describe the camera movement and action, and generate professional bridging footage that would otherwise require expensive VFX work.

Product Morphing and Showcases

Show product transformations, color variations, or feature changes with polished video transitions. A cosmetics brand can morph between shade options; a car manufacturer can transition between trim levels—all with smooth, controlled motion.

Before-and-After Content

Fitness transformations, home renovations, seasonal landscape changes—any scenario that tells a story through contrast benefits from smooth, professional video transitions between two states. The dual-frame control ensures both your “before” and “after” moments land exactly as intended.

Character Animation and Pose Transitions

Animate characters moving from one pose or expression to another. Game developers, animators, and content creators can quickly prototype character movement without manual keyframing, using the text prompt to guide the style and timing of the transition.

Time-Lapse and Temporal Effects

Create artificial time-lapse videos with controlled start and end points. Simulate sunrise to sunset, season changes, or architectural construction progress with natural-looking temporal interpolation.

Storyboard Previsualization

Transform static storyboard frames into animated sequences. Provide your key beats as start and end images, and the model generates the motion between them—perfect for pitching concepts, testing editorial flow, or previewing camera moves before committing to production.

Getting Started on WaveSpeedAI

Using Vidu Q3 Start-End to Video on WaveSpeedAI takes just a few steps:

Upload your start image — the first frame of your video
Upload your end image — the last frame of your video
Write your prompt — describe the motion, action, and transition between frames
Set duration — choose your video length (default: 5 seconds)
Choose resolution — 540p for speed, 720p for balance, or 1080p for maximum quality
Adjust motion (optional) — control movement intensity with the amplitude setting
Enable audio (optional) — toggle synchronized audio and background music
Generate — submit and download your completed video

WaveSpeedAI’s infrastructure delivers fast inference with no cold starts, so your videos generate quickly regardless of demand. The REST API integrates directly into existing production pipelines and creative workflows.
