  • framebuffer:
    • provides 12 or 24 bits of colour information to an Amiga screen
    • 1.5 MB as two banks of 12 bit RAM
    • double buffered 12 bit (4096 colours) animations or a single buffered 24 bit (16.7 million colours) image
    • 768×625 (PAL) or 768×525 (NTSC) maximum resolution
  • framegrabber:
    • realtime digitizing at up to 25 fps
    • freeze, grab and store 12 or 24 bit full screen live RGB video in real time frame grabbing
    • composite and Y/C video requires an RGB splitter or the optional Video Interface Unit
  • flicker fixer:
    • duplicates and enhances the A3000's display enhancer circuitry
    • even de-interlaces external live video
    • the HD15 VGA output is software switchable between 15 and 31 kHz
    • works only in 12 bit mode
  • picture in picture:
    • freeze, resize, move or scale live incoming RGB video in a window
    • reverse-PIP - place a fully functional movable and scalable Workbench window on full screen live video
    • works in 12 bit mode only
  • genlock:
    • separate composite and component (RGB + sync) genlocks
    • three genlock modes - controlled by a switch on the back of the board:
      • Amiga graphics only
      • keyed source - allows external video to show through the background
      • full external - direct feed of the RGB signal so it can be seen what the camera is pointing at or the live video to show through every colour but the background
  • separated RGB, composite and Y/C inputs
  • composite and Y/C outputs
  • optional Video Interface Unit:
    • connects to the 26 pin I/O connector of the IV24
    • built-in RGB splitter converts the composite and Y/C inputs into RGB

  • connects to the inline Zorro and video slots of the A3000
  • can be installed in the A2000 with an optional video slot adaptor card
