On the Inputs screen you can view the currently selected video and audio input
sources and map audio sources to the channels supported by Final Cut Pro (more on
this later). Two information panes in the screen are provided: Video Input and Audio
Input.
AJA Control Panel, Inputs Tab
Input Select Tab Settings
Video Input—the pulldown menu allows you to see and change what's currently
selected and the video format that Io XT has detected (if any). In the example
shown previously, it 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 shown in blue, you can tell that
it matches the framebuffer's primary format selected in the “Formats” screen. By
looking at the input source, you can determine how the primary format should
likely be set (unless you want to perform a conversion on 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 lateral time code (LTC) input.
Audio Input—this pulldown menu allows you to pick where the audio comes from. Io
XT supports up to 8 channels of embedded audio. You can choose out of 16
channels embedded in the SDI which 8 to bring in (1-8 or 9-16). Here you can also
select which two channels from the 8 embedded would be mapped to Final Cut
Pro if only two channels were selected in that application.
