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 note that the incoming video streams have to be synced correctly before. We recommend to use using Frame Stores for such a recording workflows. Please beware also note that this is an AJA-only feature. Please beware that Additionally, there is a special use case, when using the AJA Corvid 88 video device. Here In this case you have to use Input1 Input 1 & 5 to distribute the incoming audio to all other channels. This , as this is unfortunately a limitation peculiarity of the AJA video device. |
Video Mode: select the Video mode . The video mode has to match and ensure that it matches 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 limited to HD modes and for AJA devices. |
AJA Frame Buffer: This settings setting 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 RP-188 (SDI Embedded) Timecode (AJA only): This option enables the “SDI Embedded” Timecode Source option for this an AJA Input Channel. By default, this option is enabled.
| Info |
|---|
If you experience Frame Drop Errors, disable this option and try it again. |
Enable End-To-End SDI If Available: This option does work for some specific AJA devices, like such as the KONA 1 or the KONA LHe Plus, where the incoming signal will be passed to the output port, once the just:in engine Just In Engine application is running.
Chunk Length: defines the maximum length of the recorded Video. The maximun maximum 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.
Port: port to access the Channel the Channel from just:in mac over an IP connection. Default The default port for the first Channel is 50000, 50001 for the second Channel, and so on. You can leave keep this setting if the chosen ports are not in use on this machine.
...
VTR Preroll in Seconds: set the desired VTR preroll value in seconds (1-10). Default The default value is 5.
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.
...
Don't Cache: files are directly written to disk, no caching is done.
Cache (Default): tells the internal macOS ethernet Ethernet controller to cache data in order to flush it to the network stack later to improve write performance.
...
Ignore: Channel ignores timecode breaks.
Create new file: Channel creates a new file upon a timecode break.
Preview
You can manually override the resolution, framerateframe rate, 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 informationsinformation.
Resolution: two resolution options are available:
High: 640x360px
Low: 480x270px
Frame rate: the preview frame rate can be changed between 0 (=native framerateframe rate) and 30 (if the channel framerate frame rate is higher then than 30, then the preview will be limited to 30fps).
Quality: can be changed between 10 10% and 100%.
