Render In Seconds

Generate a fluid five-to-ten second cinematic clip at faster than real-time speeds.

What Lucy is good at

Built on an accelerated diffusion transformer architecture, Lucy combines sub-ten-second rendering speeds with precise camera control and reference identity preservation.

Sub-10s Motion Generation

Accelerated diffusion transformer architecture delivers five- to ten-second video sequences in six to ten seconds, enabling immediate creative feedback loops.

Reference Identity Preservation

Retain the core layout, subject structure, and lighting palette of your input reference frame while injecting natural physics and camera movement.

Dynamic Camera Choreography

Direct sweeping crane shots, subtle pushes, and dramatic pans with natural spatial depth and perspective handling across 16:9 and 9:16 canvases.

Organic Physics Simulation

Simulate atmospheric movement, shifting dappled illumination, and responsive fluid motion across character garments, hair, and environmental elements.

Frequently Asked Questions

Lucy generates 5-to-10 second video clips in approximately 6 to 10 seconds, achieving faster than real-time generation speeds. This near-instant turnaround enables rapid motion sketching, iterative storyboarding, and interactive visual brainstorming without waiting on batch render queues.

Lucy accepts a reference image alongside a guiding text prompt, supporting both 16:9 landscape and 9:16 vertical aspect ratios. For optimal pixel mapping, upload clean, pre-graded source images (such as 1280x720 or 720x1280) and match the aspect ratio setting to your source frame's native proportions.

Lucy excels at rapid motion prototyping, cinematic B-roll drafting, animating static character portraits, and A/B pre-visualization for commercial storyboards. Its core strength lies in preserving the composition, lighting, and subject identity of the source image while introducing fluid physical movement.

Lucy is not designed for final-cut VFX production requiring pixel-perfect hand anatomy or legible typography, as high-speed diffusion can introduce finger smearing and text distortion. It is also not suited for long-form narrative consistency across multi-scene sequences longer than 10 seconds.

Lucy was developed by Decart and released in early 2026. It is built upon an accelerated Wan-2.2 Diffusion Transformer (DiT) architecture paired with Decart's high-efficiency inference stack.
