2 In the Global Configuration area, set the options described below:
Video Standard

Under Video Standard , select the video standard (i.e., NTSC or PAL).
Genlock

Under Genlock , select the source and resolution setting.
The available Source settings are:

Internal — this uses the internal clock of the server rather than
referencing to an external reference source.

timing derived from video input 1.

External — this references the video outputs to the external reference
signal applied to the REF IN connector. This is the recommended
setting.
The available Resolution settings are:

Standard — use for bi-level 525 or 625 line reference.

HD1080i — use for tri-level 1080i reference.

VBI and Closed Captioning
a Under VBI and Closed Captioning , set the start and stop lines for stored
closed captioning and other ancillary data. This data is stored as clip
essence.
b Select the SD MPEG Extended Height check box to compress the
ancillary data. This only applies to SD-only, MPEG 4:2:2 configurations.
Extended Record
a Select the Extended Record check box to increase the number of vertical
pixels recorded to include those that make up the VBI data closed
captioning. This saves space if the recorded VBI lines are set to the same
values. This only applies to SD MPEG 4:2:2 configurations.
