The Vidi-Amiga 12SV is a video digitizer which connects to the parallel port of the Amiga. It is capable of capturing realtime video in 16 greyscales, or colour stills at up to 4096 colours (HAM-6) from either a PAL or an NTSC source including SVHS. An absolutely still image is required for colour grabs, because the red, green and blue components are captured independantly then overlaid within the software. Fast processors not only improve the speed of the capture but increase the tolerance of a bad quality video source. The Vidi-Amiga SV also has the ability to digitize the sound from a video source.
