DS Keyer Tab Screen The KONA 3G has a hardware-based downstream keyer that is ideal for putting logos, “bugs” or
other video material with an alpha channel on top of video being played out or printed to tape.
A typical application would be putting a television station's call letters or channel over program
video content. Keyed video can be from the KONA's internal Frame Buffer (from storage, video
In, KONA TV, etc.) or from a graphics file that has an alpha channel (PhotoShop etc.).
