What makes Lucy Edit stand out

Lucy Edit is a high-fidelity video-to-video editor optimized for fast, text-driven transformations that preserve subject identity, motion continuity, and scene geometry. By targeting edits rather than regenerating every frame, Lucy Edit maintains stable structure, believable lighting, and consistent materials across time. It interprets concise prompts to restyle outfits, replace backgrounds, or apply aesthetic grades while keeping camera movement and pose intact. Built for production reliability, Lucy Edit delivers realistic results with minimal flicker and strong adherence to requested scope. With lightweight inputs and predictable behavior, Lucy Edit adapts cleanly to diverse footage and editorial pipelines.

Key capabilities:

  • Temporal stability: Lucy Edit keeps identity and textures consistent across frames.
  • Structure preservation: maintains pose, layout, depth, and material response.
  • Background control: replaces or cleans plates while respecting occlusion and parallax.
  • Wardrobe restyling: Lucy Edit swaps outfits while retaining body silhouette and motion.
  • Scoped changes: honors constraints like background only or keep face unchanged.

Prompting guide for Lucy Edit

Provide a video_url for the source clip and a prompt that states the exact change. Lucy Edit responds best to concrete, scoped instructions that name what to edit and what to preserve. To avoid drift, tell Lucy Edit to keep identity, camera motion, and composition intact. For broad looks, ask for a global grade or background swap; for precise fixes, narrow the area. Lucy Edit iterates quickly, so refine in short passes and review results. When in doubt, guide Lucy Edit with spatial terms and priorities.

Examples:

  • Background-only swap: "replace office background with a sunny beach, keep subject and motion" - Lucy Edit changes only the environment.
  • Wardrobe restyle: "turn the jacket into red leather, preserve pose" - Lucy Edit retains identity.
  • Localized cleanup: "remove floor cables, do not alter shadows or reflections" - respects lighting and depth.
  • Global grade: "apply cinematic teal-orange, keep skin tones natural."

Pro tips:

  • State constraints clearly: keep subject, keep pose, change background.
  • Use precise spatial terms: left, right, background only, face only.
  • Limit adjectives; favor 2-3 strong descriptors for style.
  • Supply clean, steady footage and crop irrelevant regions.
  • Iterate with short updates; check temporal continuity.
