Video Input: The pulldown menu allows you to see and change what's currently selected and shows
the video format that Io XT has detected (if any). The figure above shows that video is
selected at the HDMI input and the format is 1080i with a frame rate of 29.97. Since this
text is blue, you can tell that it matches the framebuffer's primary format selected in the
“Format” screen. By looking at the input source, you can determine how the primary
format should be set (unless you want to perform a conversion on the input.) If you wish
to select a different input use the pulldown to select either SDI 1, 2 or Dual Link for two-
wire 4:4:4 RGB, or Stereo 3D. For 3G single-link, choose the SDI Source used and select
Stereo 3D from the SDI pulldown menu.
Use the LTC/Ref menu pulldown next to Video Input to select how the LTC BNC is used:
selecting Reference means it’s used a Reference standard; selecting LTC means it’s used
for linear time code (LTC) input.
System Genlock: For video stability and proper system operation, you can genlock all equipment to house
sync, however genlock is not required for Io XT/4K due to excellent freerun accuracy. To
connect genlock, use a black burst generator output looped through the system. On the
Io XT/4K house sync is connected to “LTC/Ref In”.
NOTE: Be sure to set the Reference/LTC connection to Reference in the pulldown menu in the Video
Input pane.
