> ⚠️ **Important**   
> ⚠️ Before you start capture, be sure to check that the appropriate options are selected in the Capture panel (see [Capture properties)](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10588821).

**To capture live data:**

1. Ensure your system is connected and calibrated and that Evoke is not in Review mode.
2. Open the **Capture** panel (**View** menu > **Capture**).
3. In the **Capture Info** section, ensure the **Capture Folder** location is as required.
4. In the **Capture Name** box, enter a name for the new capture. If you want a number to be automatically appended to the file name and incremented on each successive capture, ensure **Auto-increment Name** is selected.
5. Do one of the following:
  - If you don't want to select any further parameters, go to step 7; or
  - If your capture requires any further setup, for example, if you are using remote triggering, in the **Auto Capture** section,** **supply the necessary information:
    - **Start/Stop on Timecode** To start and end capture data at a specified timecode, select the check box and enter the required timecode.
    - > Macro (anchor)

**Stop After Duration** To end the capture automatically after a specified number of seconds, select this check box and enter the required number of seconds.
    - **Broadcast Capture** <span style="color: #000000"> To send a remote trigger </span><span style="color: #FF0000"> </span><span style="color: #000000">over the network via UDP</span><span style="color: #FF0000"> </span><span style="color: #000000"> to control capture start and stop times, </span> <span style="color: #FF0000"> </span><span style="color: #000000">select this check </span><span style="color: #FF0000"> </span><span style="color: #FF0000"> </span><span style="color: #000000">box. </span><span style="color: #FF0000"> </span><span style="color: #FF0000"> </span>
    - ** ****Triggered Capture**** ** To receive a remote trigger to control capture start and stop times, select this check box. <span style="color: #FF0000"> </span><span style="color: #000000">A trigger can originate from either a voltage signal connected to your Vicon system via a Vicon connectivity device (Vicon Lock) or over the network via </span><span style="color: #000000">UDP</span><span style="color: #000000">.</span><span style="color: #FF0000"> </span>
    If you are sending or receiving a signal via UDP, also specify the **Port** for the capture and from the **Address** list, select the required IP address.   
For information on the format of UDP broadcast and trigger notifications, see [Control remote capture](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10588312).
  For more information on the capture settings, see [Capture properties](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10588821).
6. If you selected the **Start On Timecode** check box, start the timecode source from which the data capture is to be triggered; otherwise, go to Step 7.
7. In the **Capture** section, select the check boxes next to each data source that you want to capture. For more information, see [Capture properties](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10588821).
  :check_mark: **Tip**   
By default, Evoke captures raw camera data (.*x2d*) but all data available for review is captured in the review file (.*mcp*). If you do not select the check box next to **Capture Processed Data**, you may not see your data when you open it for review.
8. When you are ready to begin capturing, at the bottom of the **Capture** panel, click **Start Capture**.  
The **Duration** number (mm:ss) increases as the capture proceeds.  
If you did not specify a number of seconds in the **Stop after Duration** box (see [step 5](#AutoStop)) or if you decide to end the capture before the specified time, click **Stop Capture** when you have finished capturing.  
To abandon the capture without saving any data, click **Cancel**.

Each successful capture is listed in the **Captures** section of the **Review **panel (**View **menu > **Review**). If required, you can play back the captured data by double-clicking the capture name and then clicking the Play button at the bottom right of the **Workspace** view pane (see [Review captures](https://vicon-help.atlassian.net/wiki/spaces/Evoke16/pages/10588232)).
