Since v4.0, the configuration of Devices (previously known as Engines) and Channels is done within just:control (User Interface) and this process is working the same way for just:in mac and just:in linux engines/channels.
Basics
The Configuration Panel for both just:in mac and just:in linux can be found within just:control (more info here) and all Devices are managed here. Therefore a central configuration for all available Devices and Channels is available. There is no need to check settings on each and every just:in engine machine. The only required step on the engine machine is to start the engine application.
Presets
Presets offer a quick and easy way to predefine your settings.
Capture Presets: Define Codec/container settings and other Capture Preset related options like Audio Mapping, Burnt-In Timecode option or Image/Logo Overlay
Destination Presets: Set recording path(s)
Naming Presets: Define naming strategy for recorded files
Metadata Sets: Flexible templates for metadata elements
Marker Presets: Define custom Markers, which are then visible in Adobe Premiere Pro
Tasks: Pre- and/or Post-recording Tasks, which get executed at every start and/or stop recording process
