Smart GreenScreen is a professional chroma key app for macOS and iOS with tracking markers, overlay support, and high-resolution PNG export. It replaces a selected background color (for example green) with another color and helps with camera tracking, livestreams, conferencing, and studio production workflows. Core Features Greenscreen / Chroma Key • Replaces a background color with another color in real time. • Adjustable RGB and brightness for both background and marker colors. • 25 color presets for fast setup. • “Slider for marker” toggle: sliders can control either background or marker color. • Tab key toggles greenscreen on/off (black when off). • Overlay image with alpha support (PNG transparency). Tracking Markers • 4 marker types: 1) Cross 2) Triangle target 3) Checkerboard circle 4) Circle+Cross • Up to 12 markers simultaneously. • Adjustable marker size (3–25% of screen). • Adjustable stroke width for cross-style markers (2–12). • Invert option for better visibility. • Add, move, and delete markers with dedicated modes and clear visual mode indicators. • Default marker color is black on first launch for strong contrast on green backgrounds. Overlay Tools • Collapsible Overlay section in Settings. • Base overlay image: Load/Remove PNG with transparency. • Floating PNG overlays: import multiple transparent PNGs, place them freely on screen, and position them like markers. • Floating overlays can be moved and deleted using the same Move/Delete workflow as markers. • Dedicated delete action for the overlay image.
