Io X3 Capture, Display, Convert v16.2 39 www.aja.com
DS Keyer Screen
The Io X3 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 Io X3 internal Frame
Buffer (from storage, video In, etc.) or from a graphics file that has an alpha
channel (Photoshop etc.).
Settings in the DS Keyer Screen provide control over how the keyer operates and
whether it’s turned on or off.
