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 may configure one or multiple Channels.
...
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)
...
Video Mode: select the Video mode. The mode has to match the Video Signal, which is attached to the selected Channel. If it does not match, a warning will be shown (No Signal). Also beware Beware that here are only video modes available, which are matching the Device FramerateFrame rate.
Enable End-To-End SDI If Available: This option does work for some special 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.
Chunk Length: defines the maximum length of the recorded Video. The maximun Chunk Length is 12 hours, the default option is 2 hours.
If the Recording does not reach the entered Chunk Length
...
, the recorded clips will be automatically truncated to the expected recorded length.
Recording exceeds the entered Chunk Length: a new Recording (generating a new clip) will automatically be started.
Start Timecode: enabling this option overrides the local time or incoming timecode and makes every new clip start with the defined timecode value.
...
Restart On No Signal if Not Recording: If this option is enabled, the channel will automatically restart after a signal loss (only in Idle Mode). Options are:
Close container, write to new: Recording to the current file will be stopped and as soon as there is a valid signal again the recording will start into a new file.
Close container and stop: Recording will be stopped when channel detects a signal loss.
Cache Options:
Don't Cache (default): files are directly written to disk, no caching is done.
Cache: tells the storage controller to cache data in order to flush it to disk 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.
Calendar: select the Calendar which you would like to use with this Channel for Scheduled recordings. You may use any Calendar which can be imported to Apple Calendar app. This can be a local Calendar like the one which was created by the just:in Channel or an iCloud or Gmail Calendar. Contact us for more information.
Preview
...
You can manually override the resolution, framerate and the quality of the Video Previews of the within just:in user interfacecontrol. This may be helpful to increase performance when displaying many Channels in the just:in user interfacecontrol. Please see Channel Preview Options below for more informations.
Resolution: two resolution options are available:
High: 640x360px
Low: 480x270px
Frame rate: the preview frame rate can be changed between 0 (=native framerate) and 30 (if the channel framerate is higher then 30, then the preview will be limited to 30fps).
Quality: can be changed between 10 and 100%.

Enable a Channel for Recording
After configuring a Channel you need have to enable it by clicking on the checkbox next to the Channel name. The Channel can now be used by the just:in user interfacecontrol. When quitting and relaunching just:in Engine, previously activated Channels will still be active, so there is no need to open the just:in Preferences Configuration Panel and activate them the Channels again.
...
| Warning |
