### Key Features

* **Precise Targeted Editing:** Edits specific elements such as character expressions, body movements, camera position, camera movement, style, backgrounds, weather, colors, or materials while keeping the rest of the scene stable.
* **Scene Preservation:** Maintains original length, framing, motion timing, and surrounding context during edits so only the intended changes appear.
* **Creative Recreation:** References the pacing, shot composition, and visual expression of existing videos while replacing products, characters, or assets for new commercial or social content.
* **Multimodal Edit Inputs:** Accepts one primary video plus supporting clips and image/subject references (up to 5 videos totaling 30 seconds) to guide targeted changes.
* **Efficient Iteration:** Reduces full regenerations by allowing focused revisions on promising shots for faster production workflows in advertising, animation, and storytelling.
* **Element Manipulation:** Adds, removes, or replaces subjects and objects, or adjusts style and environment, without rebuilding the entire scene from scratch.
