Core Capabilities
Camera and Shot Generation
- Novel View Generation: Create new camera angles from existing footage (reverse shots, low angles, medium shots)
- Shot Continuation: Generate seamless next shots in video sequences
- Motion Transfer: Apply camera motion from one video to a new starting frame
Object Manipulation
- Object Addition: Insert new elements into scenes (crowds, products, props, fireworks) with proper lighting and perspective
- Object Removal: Remove unwanted elements or distracting objects from footage
- Object Replacement: Replace or retexture existing objects using text prompts or reference images
- Green Screen Extraction: Isolate subjects with precise edge detection for transparent or colored backgrounds
Environmental and Atmospheric Changes
- Location/Environment Modification: Change settings, locations, seasons, and time of day
- Weather Effects: Add atmospheric elements like rain or other weather conditions
- Lighting Adjustment: Transform lighting conditions (golden hour, dawn, sunset) with natural shadow and reflection updates
Visual Style and Appearance
- Style Transfer: Apply aesthetic styles to footage using reference materials
- Character Appearance: Modify actor age and appearance through text prompts
- Color Modification: Change object colors using color swatches or descriptive prompts
- Relighting: Adjust scene mood and lighting conditions
