The Video Centre Pro is an external genlock for the Amiga which supports fade to black and fade in/out although it does not support chroma-keying. It has composite input and output, as well as an SVHS input and output. This device was usually supplied with a cable (approx 1.2m) with 23pin connectors at both ends. One of which connects to the Amiga and the other connects to the genlock.
