Crystal Vision has unveiled Lkey 3, which the company described as its most advanced linear keyer.

It has been designed for the highquality keying of real-time graphics generated by an external graphics machine over a 3Gb/s, HD or SD video stream. New timing functionality includes built-in video delay and frame synchronisers, while enhanced masks offer adjustable edge softness for blending between masked and unmasked areas to create a more natural-looking edge.
