What is a Channel?
A Channel is a virtual representation of a Video Device or a NDI NDI®5 Source within the network. Depending on the number of inputs, you can configure one or multiple Channels.

Audio Input option “SDI”: When using this option, it is possible to distribute the incoming audio of SDI Input1 to all other Channels. Please beware that the incoming video streams have to be synced correctly before. We recommend to use Frame Stores for such a recording workflows. Please beware that this is an AJA only feature. Please beware that there is a special use case, when using the AJA Corvid88Corvid 88. Here you have to use Input1 & 5 to distribute the incoming audio to all other channels. This is unfortunately a limitation of the AJA video device. |
...
AJA Frame Buffer: This settings overwrites the default Frame Buffer value of an AJA Channel. This setting is required for UHD recording workflows, where Channel Frame Buffer can be set to a higher value, in order to avoid any Dropped Frames while recording.
Enable RP188 RP-188 (SDI Embedded) Timecode (AJA only): This option enables the “SDI Embedded” Timecode Source option for this AJA Input Channel. By default this option is enabled.
...
Enable End-To-End SDI If Available: This option does work for some specific AJA devices, like the Kona KONA 1 or the LHePlusKONA LHe Plus, where the incoming signal will be passed to the output port, once the just:in engine application is running.
...
Ignore: Channel ignores timecode breaks.
Create new file: Channel creates a new file upon a timecode break.
