Wings Insertion
Option +WINGS allows a symmetrical L-R wings insertion to be integrated
into the card program video output. Wings video is accommodated using a
separate wings SDI input. The wings user interface displays wings timing
relative to the card output video, allowing wings timing offset to be adjusted
such that wings can be properly framed. (The option and its host card does not
provide timing offset control of the wings video; offset must be provided by a
external frame sync card or device controlling the wings video feed.)
The wings L/R insertion width can be manually configured, or can be set to
automatically track with aspect ratio as set by the host card (on cards
equipped with aspect ratio control).
