Using Part Time Channels
in the Liberty Recorder

Introduction

The Part Time Channels (PTC) feature in the Liberty Recorder allows for the recording of both the audio and video of various media, on a part-time basis, according to the needs of the court. This feature can be particularly useful for evidence presentation systems and other AV presentations that are not active on a full-time basis. The media being captured can be from any of:

  • A third-party application.
  • A hardware device.
  • Or an NDI Source.

The operator manually controls the times during which the PTC is being recorded by use of a control button located directly beside the regular "Record" button, as seen in the screen capture below.

PTC Control Button

After the PTC Control button is clicked, the Recorder will present a list of PTCs, any of which may be activated by their selection, as seen in the screen capture below.

The same procedure is reversed to stop recording the PTC.

Recording a Third-Party App

The "Third-party App" recording function of the PTC facility allows for the recording of other applications running on the computer, including applications like Zoom and Teams or Youtube running in a browser. Both the audio and the video from the other application can be recorded. If "Third-party App" is selected, the dialog Window below will be displayed and must be configured appropriately.

PTC 3Rd Party Settings

  • "Name" is used to identify this Third-party app capture facility and associated settings. It will be displayed in the list of available PTCs, when the PTC button beside the Record button on the main Recorder Window is clicked.
  • "Enable Audio Capture" as applicable to have the PTC record audio. Audio settings include:
    • "Channel Name", used to identify the audio channel in the main Window of the Recorder.
    • "Description", a comment about this capture.
    • "App Input Device", the microphone or other input for the audio that is being sent to the other participants in a conference meeting. Note that, if this device is already part of the multi-channel recording configuration, then it will not be duplicated in the captured audio.
    • "App Output Device", the speaker or similar device where the audio from the third-party app will be played so that local participants can hear the associated playback.
  • "Enable Video Capture" as applicable to have the PTC record video from the computer screen. Detailed video settings can be set by opening the "Settings for Screen Capture Dialog".
    • "High Dynamic Video" may be toggled to allow video capture to successfully capture the third-party video.
    • "Save Video in Recording File" determines if the video will be saved into the recording file.
    • "Automatically show Video Window" determines if the video Window for the recorded video should open automatically, when the video is being captured.

If video is to be captured, then the "Settings for Screen Capture" shown in the Window below must be configured.

PTC Settings for Screen Capture

In the Settings for Screen Capture Window, first select whether the capture will be for a specified target Window, or for a pre-determined area of the screen. In the first case, specify the Window to be captured. In the second case, click on the Region "Select" button and use the mouse to define the area of the screen to be recorded.

Set the "Highlight Capture Area" and "Automatically keep the target area in the foreground" settings as appropriate.

Recording a Hardware Device

If a Hardware Source is chosen for a PTC, then the "Hardware Source" settings, as seen in the screen capture below, must be configured appropriately. Reference the documentation on defining hardware devices for further details on configuring a hardware device.
