## What is Smart GreenScreen?

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.

High-Resolution PNG Export (Unique Feature)
• Export the current greenscreen scene as PNG, including markers and overlays.
• Preset export sizes from HD up to 8K.
• Custom pixel size input for any workflow.
• iOS export options:
  • Share sheet export (AirDrop, Messages, Mail, etc.)
  • Save to Files / iCloud
• macOS export via native save dialog.
• Great for VFX planning, camera-tracking references, scene setup docs, and still frame delivery.

Keyboard Features (iOS)
• Optional on-screen keyboard for blind typing on the greenscreen.
• “On marker tap only” mode: keyboard appears when tapping a marker, hides with Enter.
• Optional clean typing mode with reduced suggestion/autocorrect distractions.
• External keyboard support with Tab toggle behavior matching macOS.

Menu Access
• macOS: Shift+Click or Cmd+M.
• iOS: 3-finger tap (always available), configurable multi-tap (3–10), or long press.

Settings & UX
• Save & Load Greenscreen Presets
• Auto-saved settings.
• Reset to defaults.
• Collapsible sections for clearer navigation (Colors, Marker, Overlay, Keyboard Setup, Presets, Export).
• Consistent icon-based controls and improved spacing for fast operation during production.

Technical Details
• Built with SwiftUI.
• Localization: DE, EN, ES, FR, IT, JA, PT, RU, ZH.
• Settings stored as JSON in Application Support.
• macOS: window + fullscreen, optional auto-hiding title bar.
• iOS: fullscreen layout optimized for notch and different screen sizes.

Target Audience
• Video production / post-production
• Livestreaming
• Video conferencing
• Camera tracking with greenscreen backgrounds
• Presenters and performers using marker-based typing workflows
