Features

Lucy-edit-dev — Ultra-Fast Text-Guided Video Editor

Lucy Edit Dev is a state-of-the-art text-guided video editing model. Give it a source video and a short prompt, and it will transform the content while preserving timing, camera motion, and overall composition.

What Lucy Edit Dev can do

Prompt-based video editing Change clothing, add or remove objects, alter styles, or adjust scene appearance using natural language instructions.
Structure-preserving edits Keeps original framing, motion, and pacing while modifying only the requested elements.
High temporal consistency Edits stay stable across frames, avoiding heavy flicker or “teleporting” artifacts.
Fast turnaround Optimized for quick responses so you can try multiple prompts and versions in minutes, not hours.

Inputs

video (required) The source clip to edit. The output duration matches the input duration (subject to platform limits).
prompt (required) A concise description of the desired edit, such as: “Turn the city into a futuristic neon metropolis” “Replace all cars with horse-drawn carriages” “Dress the people in medieval armor”

Pricing

Price per second: $0.030
Maximum supported duration per request: 120 seconds

How to use

Upload or paste the URL of your source video.
Write a clear prompt describing what should change and what should stay the same.
Click Run.
Preview the edited clip; if needed, tweak the prompt and re-run to iterate quickly.

Tips for best results

Keep prompts focused and specific (“Add light snowfall and winter coats” is better than “Make it different”).
Use reasonably clear, well-lit footage; very dark or heavily compressed videos reduce edit quality.
When refining a look, keep the core prompt and only adjust small details to get consistent outcomes.
