Introducing Lucy Edit Pro: Studio-Quality Video Editing Through Natural Language

The era of frame-by-frame video editing is giving way to something far more intuitive. Decart AI, the Israeli startup that achieved a $3.1 billion valuation in just two years, has developed Lucy Edit Pro—a text-guided video editing model that transforms how creators modify and enhance video content. Now available on WaveSpeedAI, Lucy Edit Pro delivers studio-grade results through simple natural language prompts, eliminating the need for masks, keyframes, or tedious manual adjustments.

What is Lucy Edit Pro?

Lucy Edit Pro is a high-fidelity, instruction-guided video editing model built on the powerful Wan2.2 5B architecture. Unlike traditional video editors that require extensive manual work or AI generators that create content from scratch, Lucy Edit Pro takes an existing video and precisely transforms specific elements based on your text descriptions—while preserving everything else exactly as it was.

The model represents the production-ready evolution of Decart’s Lucy Edit technology. Where the open-weight Dev version excels at experimentation and prototyping, the Pro version prioritizes visual fidelity, temporal stability, and crisp 720p output quality suitable for professional workflows.

What makes Lucy Edit Pro remarkable is its structure-preserving capability. Feed it a video of someone walking through a city street with the prompt “transform her outfit into a regal medieval gown with a jeweled crown,” and the model redraws only the clothing and accessories frame by frame. The subject’s motion, the camera angles, the timing, and the overall composition remain untouched—only the requested elements change.

Key Features

Text-Guided Precision Editing Describe your edit in plain English, and Lucy Edit Pro executes it across every frame. No technical expertise required—prompts like “replace the kitchen with a futuristic laboratory with glowing panels” translate directly into cinematic transformations.

Perfect Motion Preservation The model maintains original camera movements, pacing, and subject blocking throughout the edit. This means you can make dramatic visual changes without losing the natural flow and timing of your footage.

High Temporal Consistency One of the biggest challenges in AI video editing is frame-to-frame drift and flickering, especially on detailed elements like hair, clothing textures, and accessories. Lucy Edit Pro specifically addresses this with enhanced temporal stability, delivering smooth, coherent results across extended sequences.

720p Production Quality Unlike models limited to lower resolutions, Lucy Edit Pro outputs at 720p—sharp enough for social content, previews, concept shots, and many production use cases.

Extended Duration Support Process videos up to 120 seconds per request, giving you flexibility for longer content pieces without breaking them into fragments.

Flexible Resolution Options Choose between 480p for quick drafts and iterations or 720p for final production quality, optimizing your workflow and costs based on project needs.

Use Cases

Content Creators and Social Media Rapidly iterate on video concepts by testing different visual styles, outfits, or settings without reshooting. Transform a casual video into multiple themed versions for different platforms or campaigns.

Film and Video Production Create convincing VFX prototypes and concept shots before committing to expensive post-production. Re-dress actors in period costumes, add environmental details, or visualize scene transformations during pre-production planning.

E-Commerce and Product Marketing Generate product variations and lifestyle imagery at scale. Show the same model wearing different outfit configurations or place products in diverse settings without organizing multiple photo shoots.

Game Development and Animation Prototype character designs and scene concepts quickly. Transform reference footage into stylized versions that match your artistic direction, accelerating the creative development process.

Advertising and Brand Content Customize video content for different markets, seasons, or campaigns by swapping visual elements while maintaining the core message and motion of your footage.

Creative Experimentation Turn ordinary footage into extraordinary content—transform urban scenes into fantasy landscapes, add magical elements to everyday moments, or reimagine characters in entirely new contexts.

Getting Started on WaveSpeedAI

Using Lucy Edit Pro through WaveSpeedAI is straightforward:

1. Upload your source video via URL or direct upload. The model accepts MP4, WebM, and QuickTime formats.

2. Select your resolution—480p for faster, more affordable drafts or 720p for higher-quality final output.

3. Write your prompt describing exactly what should change. Be specific: “Replace her clothes with a red sci-fi pilot suit with metallic details” will outperform vague instructions like “make it futuristic.”

4. Run the model and review your edited clip in minutes.

5. Iterate as needed by refining your prompt and regenerating. Keep your core description stable while adjusting specific details for consistency.

For optimal results, use well-lit footage without extreme compression or heavy motion blur. Prompts of 20-30 descriptive words tend to produce the best outcomes.
