What is a Channel?
A Channel is a virtual representation of a Video Device or a NDI Source within the network. Depending on the number of inputs, you can configure one or multiple Channels.
Channel Settings AJA/BMD
| Info |

Depending on your Video device(s) the Channel Settings can look slightly different. |

Settings
Below you can find a description of each Channel Setting:
Device: Select the Video Device (AJA/BMD) for this Channel.
Input Mode: Select the Input Mode for this Channel. Available options, depending on the Device are:
SDI (Blackmagic DeckLink)SDI (AJA)
SDI (AJA 4x4K-Quad)
SDI (AJA 12G)
HDMI (AJA)
Input: Choose the Input of the Device for this Channel here (for BMD Channels, only option “Input #1” is available).
Audio Input: Choose between different Audio Input (AJA/BMD) and Audio Input Channel (AJA only) options. Audio Input options are:
Auto (same as video, normally SDI)
SDI (By choosing this option, the audio input channel option can be adjusted as well)
Analog
AES/EBU
| Info |
|---|
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. |
Video Mode: select the Video mode. The video mode has to match the incoming Video Signal, which is attached to the selected Channel. If it does not match, a warning will be shown (No Signal).
| Note |
|---|
Please beware that PSF video mores are only available for HD modes and for AJA devices. |
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 End-To-End SDI If Available: This option does work for some special specific AJA devices, like the Kona 1 or the LHePlus, where the incoming signal will be passed to the output port, once the just:in engine application is running.
...
Cache Options:
Don't Cache (default): files are directly written to disk, no caching is done.
Cache (Default): tells the storage internal macOS ethernet controller to cache data in order to flush it to disk the network stack later to improve write performance. If you experience low write performance, enable caching.
Action on Timecode break:
Ignore: Channel ignores timecode breaks.
Create new file: Channel creates a new file upon a timecode break.
Preview
You can manually override the resolution, framerate and the quality of the Video Previews within just:control. This may be helpful to increase performance when displaying many Channels in just:control. Please see Channel Preview Options below for more informations.

Quality: can be changed between 10 and 100%.

Add/Remove a NDI Channel
You can add or remove NDI Channels at any time. Open the Configuration Panel and select one of the connected just:in mac devices. Then use the Plus button to add a NDI Channel.

Channels can be removed only, if they get disabled/stopped before. |
Enable a Channel for Recording
After configuring a Channel you have to enable it by clicking on the checkbox next to the Channel name. The Channel can now be used by just:control. When quitting and relaunching just:in Engine, previously activated Channels will still be active, so there is no need to open the Configuration Panel and activate the Channels again.

Once a channel is enabled, it will be available in the Connection Tab within the Inspector. |
Change a Channel Name
The name of a Channel can only be changed, when the Channel is disabled. First make sure that the Channel is not enabled and then click on the Channel Name (next to the channel checkbox), adjust the name and press enter.
