Lucy Edit Dev is an open-weight video editing model that performs instruction-guided edits on videos using free-text prompts — it supports a variety of edits, such as clothing & accessory changes, character changes, object insertions, and scene replacements while preserving the motion and composition perfectly. - 🚀 First open-source instruction-guided video editing model - 🧩 Built on Wan2.2 5B architecture — inherits high-compression VAE + DiT stack, making adapting existing scripts and workflows easy. - 🏃‍♂️ Motion Preservation - preserves the motion and composition of videos perfectly, allowing precise edits. - 🎯 Edit reliability — edits are more robust when compared to common inference time methods. - 🧢 Wardrobe & accessories — change outfits, add glasses/earrings/hats/etc. - 🧌 Character Changes — replace characters with monsters, animals and known characters. (e.g., "Replace the person with a polar bear") - 🗺️ Scenery swap — move the scene (e.g., "transform the scene into a 2D cartoon,") - 📝 Pure text instructions — no finetuning, no masks required for common edits ℹ️ Model size: ~5B params. Build on top of Wan2.2 5B. Note: The prompts above are not enriched, the model will react better to enriched prompts - as described in the prompt guideline section below. 🔥 Latest News - [2025-09-18]: Initial Lucy Edit Dev weights & reference code released. - [2025-09-16]: Diffusers integration PR opened and merged. PR #12340 . Please refer to the "Prompting Guidelines & Supported Edits" section for the best experience. Lucy Edit is built for precise, realistic, and identity-preserving video edits. Prompts with ~20–30 descriptive words work best. Using the right trigger words helps the model understand your intent. Trigger Words - Change → Clothing or color modifications - Add → Adding animals or objects - Replace → Object substitution or subject swap - Transform to → Global scene or style transformations 1. Clothing Changes ✅ Best performance. Lucy Edit excels at swapping outfits while preserving motion, pose, and identity. Example: “Change the shirt to a kimono with wide sleeves and patterned fabric.” 2. Human/Character Replacement ✅ Strong results. Works well for transforming people into new characters or creatures. Detailed prompts are key. Example: “Replace the person with a tiger, striped orange fur, muscular build, and glowing green eyes.” Example: “Replace the person with an 2D anime character, big eyes, blue gown and battle scars.” 3. Replace Objects ✅ Reliable for structure-preserving swaps. Ideal when replacing one object with another of similar scale. Example: “Replace the apple with a glowing crystal ball emitting blue light.” 4. Color Changes ⚠️ Mixed reliability. Sometimes subtle, sometimes exaggerated. Works best with precise descriptions. Example: “Change the jacket color to deep red leather with a glossy finish.” 5. Add Objects ⚠️ Often attaches to the subject. Works best for wearable or handheld props. Example: “Add a golden crown on the person’s head, decorated with ornate jewels.” 6. Global Transformations ⚠️ Effective for backgrounds or scene-wide changes, might alter the subject Alter environment or style, might, Often changes the identity of the subject. Example: “Transform the sunny beach into a snowy tundra with falling snowflakes.” Additional Notes - Strengths: Lucy Edit excels at identity conservation, edit precision, realism, and prompt adherence. - Detail matters: Longer prompts (20–30 words) describing style, appearance, and context improve results. - Frame count: 81-frame generations produce better temporal consistency than shorter clips. ☁️ Hosted API: You can access the model on our API and get 5000 free credits here . 🧨 Diffusers: Coming soon 🧩 ComfyUI: Coming soon ✅ Public Batch API. ✅ Diffusers pipeline (`LucyEditPipeline`) ✅ Remote ComfyUI custom nodes. ✅ Technical Report [ ] Local Inference ComfyUI Nodes.
