Introducing Decart Lucy Edit Dev on WaveSpeedAI

Introducing Lucy Edit Dev: Studio-Grade AI Video Editing Arrives on WaveSpeedAI

The post-production landscape just changed forever. We’re thrilled to announce that Lucy Edit Dev by Decart AI is now available on WaveSpeedAI, bringing the power of text-guided video editing to creators, studios, and developers worldwide. What once took days or weeks of manual masking, rotoscoping, and frame-by-frame adjustments can now be accomplished in minutes with nothing more than a natural language prompt.

What is Lucy Edit Dev?

Lucy Edit Dev is a state-of-the-art text-guided video editing model developed by Decart AI, the company behind breakthrough real-time video generation technology. Built on the proven Wan2.2 5B architecture with a high-compression VAE and Diffusion Transformer (DiT) backbone, Lucy Edit Dev represents a paradigm shift in how we approach video post-production.

Unlike traditional video editing that requires extensive manual work—creating masks, keyframing effects, and painstakingly adjusting each frame—Lucy Edit Dev interprets your written instructions and applies them directly to your footage. Simply describe what you want to change, and the model handles the rest while preserving your video’s original motion, timing, and composition.

This is the first open-source instruction-guided video editing model of its kind, democratizing capabilities that were previously locked behind expensive proprietary tools or required specialized VFX expertise.

Key Features

• Pure Text-Driven Editing: No masks, no keyframes, no manual rotoscoping. Write a prompt like “dress the character in medieval armor” or “transform the city into a neon-lit cyberpunk metropolis,” and watch your vision materialize.

• Superior Motion Preservation: Lucy Edit Dev maintains the original framing, camera movement, and subject motion with remarkable fidelity. Your edits blend seamlessly while the fundamental dynamics of your footage remain untouched.

• High Temporal Consistency: Forget about flickering artifacts or elements that “teleport” between frames. Edits remain stable and coherent throughout the entire clip, delivering professional-quality results.

• Rapid Iteration: Optimized for speed, Lucy Edit Dev lets you experiment with multiple prompts and variations in minutes rather than hours. The creative feedback loop has never been shorter.

• Versatile Edit Types: From wardrobe and accessory changes to full character transformations and complete scene replacements, the model handles an impressive range of modifications with consistent quality.

• Extended Duration Support: Process clips up to 120 seconds in a single request, making it suitable for substantial content pieces beyond quick social media clips.

Real-World Use Cases

Film and Television Post-Production

Transform establishing shots, modify costumes that didn’t work on set, or add environmental effects without reshoots. A scene filmed in summer can become a winter wonderland; period-accurate details can be added to contemporary footage.

Social Media Content Creation

Stand out in crowded feeds with creative transformations. Turn yourself into a fantasy character, place your content in impossible locations, or add dramatic stylistic effects—all while maintaining the authentic motion that keeps viewers engaged.

E-Commerce and Advertising

Quickly produce product variations for A/B testing. Change model outfits, swap background environments, or adjust branding elements across your video catalog without organizing new shoots.

Game Development and Concept Visualization

Rapidly prototype visual directions for cinematics. Transform reference footage into stylized concept pieces that communicate your creative vision to teams and stakeholders.

Educational and Training Content

Update outdated footage with contemporary elements, localize content for different regions, or demonstrate transformations for instructional purposes without recreating entire productions.
