You specify your requirements for recording live trials on the Recording tab. If you use the same setup each time, you can make subsequent recordings just by clicking the **Start** button.


    **To record trial data:**


1. Ensure your system is connected and calibrated and that Tracker is in **Live** mode.
2. In the **Resources** pane, click the **Recording** tab.
3. In the **Location** area, select whether your trial will be saved as **Shared** or **Private** files.
4. In the **Trial Name** box, enter a name for the new trial. If you want a number to be automatically appended to the file name, ensure **Auto Increment Trial Number** is selected.
5. If you want existing captured trial data in the same folder to be overwritten when a new trial is saved, select the **Permit Overwrite of Existing Files** box.
6. Do one of the following:
  - If you don't want to select any further parameters, go to step 7; or
  - If your trial requires any further setup, for example, if you are using remote triggering, click **Show Parameters** and supply the necessary information:
    - **Start/Stop on Remote Trigger** To use a remote trigger to control capturing start and stop times, select this check box. The remote device must be connected to your Vicon system via a Giganet.
    - **Capture before Start (secs)** To capture data before the capture start is triggered either manually (by clicking **Start**) or automatically (based on a remote trigger), select this check box and enter the required number of seconds.
    - **Stop after Duration (secs)** To end the trial automatically after a specified number of seconds, select this check box and enter the required number of seconds.
    - **Start/Stop over Network** To make a UDP broadcast to a third-party application that capture has started or stopped, select this check box and from the adjacent drop-down list, select **Send** or **Receive**. In the **Address** list, either select the IP address of the network card that will be used to send or receive the start/stop trigger message, or select **All**. In the adjacent field, specify the UDP port which is to send or receive the message. For information on the format of UDP broadcast and trigger notifications, see [UDP capture broadcast/trigger](https://vicon-help.atlassian.net/wiki/spaces/Tracker39/pages/14058586).
    - **Arm** button To set the system to a state where it is ready to accept a trigger signal for automatic capture based on a signal broadcast over the network from a remote device, click this button. If you want to enable the system to remain ready to receive subsequent network signals after the capture is stopped, click the **Lock** button to the right of the **Arm** button.
7. When you are ready to begin recording, click **Start**.
  The **Frames Captured** number increases as frames are captured.
  If you did not specify a number of seconds in the **Stop after Duration** box or if you decide to end the capture before the specified time, click **Stop** when you have finished capturing.
  To abandon the trial without saving any data, click **Cancel**.

You can play back the captured trial immediately.
