# Lucy Canonical page: https://fuser.studio/models/lucy Lucy in Fuser turns a still image and a text prompt into a short video with Decart's model. Use it for fast motion drafts and camera tests before final shots. ## Specs | Spec | Value | | --- | --- | | Inputs | Prompt (text), Image Prompt (image) | | Output | video | | Aspect ratios | 16:9, 9:16 | | Cost | 331 credits per run | Animate static visual concepts into fluid cinematic video sequences in seconds for rapid style scouting and motion pre-visualization Creator: Decart [Animate Still Frame](https://app.fuser.studio) ## How Lucy works Move from a single reference still to a finished cinematic motion draft in three frictionless steps. ### Upload Reference Frame Select a crisp 16:9 or 9:16 still image with established lighting and clear subject definition. ### Direct The Motion Prompt specific camera moves, lighting shifts, and physical actions to guide the animation path. ### 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. ## Made with Lucy Explore how creators animate concept art, fashion stills, product prototypes, and cinematic plates into fluid motion sequences. ### Atmospheric acoustic performance visual ### Dynamic luxury product reveal ### Architectural light study ### Cinematic desert pursuit draft ### High-contrast editorial movement ## What people build with Lucy From rapid storyboard pitching to lookbook motion tests, discover how creative teams integrate near-real-time video generation into their production pipelines. ### Commercial Storyboard Pre-Visualization Transform approved client mood boards and keyframes into animated video animatics within seconds to validate pacing and camera angles before production. ### Fashion Lookbook Motion Scouting Test garment flow, drape movement, and model poses from high-res editorial photography before booking commercial video crews. ### Cinematic B-Roll Prototyping Draft transitional landscape shots, atmospheric establishing frames, and texture inserts at full speed during early editing sprints. ### Industrial Design Movement Testing Animate static CAD renders and physical prototypes with realistic orbital camera rotations and shifting specular reflections. ### Social Media Campaign Iteration Quickly convert static vertical product photography into high-energy short-form motion content optimized for 9:16 mobile feeds. ## Frequently Asked Questions ### How fast does Lucy generate video clips? 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. ### What input formats and aspect ratios are supported? 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. ### What types of creative work is Lucy best suited for? 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. ### What are Lucy's limitations and when should it be avoided? 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. ### Who developed Lucy and what architecture powers it? 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. ## Try Lucy on Fuser Animate static visual concepts into fluid cinematic video sequences in seconds for rapid style scouting and motion pre-visualization [Animate Still Frame](https://app.fuser.studio) ## Related models - [MiniMax H3 Recast](https://fuser.studio/models/minimax-h3-recast.md) - [Kling O3 Edit](https://fuser.studio/models/kling-o3-edit.md) - [Kling O3](https://fuser.studio/models/kling-o3.md) - [Kling 3.0 Video](https://fuser.studio/models/kling-3-0-video.md) - [Seedance 2](https://fuser.studio/models/seedance-2.md) - [MiniMax H3](https://fuser.studio/models/minimax-h3.md) Node reference: [Lucy docs](https://docs.fuser.studio/docs/nodes/video/lucy.md)
