It allows you to record the screen of the computer with MediaRecorder. It is a software tool that is built in in MediaRecorder.</span>

<span style="color: rgb(0, 0, 0);">**<span class="FM_All_caps">IMPORTANT</span>** To record the screen of a computer other than the one with MediaRecorder installed, use an Epiphan screen capture device instead.</span>

<span style="color: rgb(0, 0, 0);">Prerequisites</span>

- <span style="color: rgb(0, 0, 0);">You record the full screen of the PC with MediaRecorder.</span>

</div><span style="color: rgb(0, 0, 0);">Other USB cameras may also work. However, it could be that you have to change the Color space to MJPG. See [Show frame rate, resolution and format](https://bookstack.noldus.com/Show%20frame%20rate,%20resolution%20and%20format).</span>

<span style="color: rgb(0, 0, 0);">You can also combine built-in screen capture with, for instance, an IP camera.</span>

## <span style="color: rgb(0, 0, 0);">Procedure</span>

1. <span style="color: rgb(0, 0, 0);">In MediaRecorder, choose **File** &gt; **Video Settings**.</span>
2. <span style="color: rgb(0, 0, 0);">From the **Video device** list, select **Medialooks Screen Capture**.</span><span style="color: rgb(0, 0, 0);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/1YFIaf56BxyTwZK9-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/1YFIaf56BxyTwZK9-image.png)</span>
3. <span style="color: rgb(0, 0, 0);">Click the **Advanced Video Settings** button to select recording options.</span><span style="color: rgb(0, 0, 0);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/RTDQcl3fApqxhsC6-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/RTDQcl3fApqxhsC6-image.png)</span>
4. <span style="color: rgb(0, 0, 0);">In the **Medialooks Screen Capture Properties** window that opens, select the frame rate and resolution in the **Output** field. Although you are allowed to select a high frame rate, the actual frame rate of the recording will depend on the processor speed of your computer. Most likely this will be in the order of magnitude of 10 frames per second.</span><span style="color: rgb(0, 0, 0);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/krwgqj1PI6SMs1xO-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/krwgqj1PI6SMs1xO-image.png)</span>
5. <span style="color: rgb(0, 0, 0);">Although this window has several recording options, the use of the built-in screen capture is designed and supported to record one window on the MediaRecorder computer only. Minimize MediaRecorder after you start recording.</span>

### <span style="color: rgb(0, 0, 0);">To re-enable settings</span>

<span style="color: rgb(0, 0, 0);">As soon as you select the screen capture device, it is used for the video preview and you cannot change its settings. The Output fields are grayed out. To enable these fields again:</span>

1. <span style="color: rgb(0, 0, 0);">Close the **Medialooks Screen Capture Properties** window.</span>
2. <span style="color: rgb(0, 0, 0);">From the **Video device list** choose **Select video device** and click **Apply**.</span>

<span style="color: rgb(0, 0, 0);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/sNnxK6TglbK09cFm-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/sNnxK6TglbK09cFm-image.png)</span>

<span style="color: rgb(0, 0, 0);">Reselect the **Medialooks Screen Capture** device again and click the video icon to re-open the Medialooks Screen Capture Properties window (see step [3](#XREF_85526_3_Click_the) above). You can now change the frame rate and resolution again.</span>

## <span style="color: rgb(0, 0, 0);">Note</span>

<span style="color: rgb(0, 0, 0);">The actual resolution of the recorded file may be lower than the value set in Output.</span>

<span style="color: rgb(0, 0, 0);">The use of built-in screen capture option is supported with a Windows text size of 100% or 125% (Control Panel &gt; Display).</span>

<span style="color: rgb(0, 0, 0);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/0msddAsJ1YjOoH2e-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/0msddAsJ1YjOoH2e-image.png)</span>

<span style="color: rgb(0, 0, 0);">If you change Windows text size to 125%, this may result in MediaRecorder capturing only part of the screen. To solve this, do the following:</span>

1. <span style="color: rgb(0, 0, 0);">Make sure MediaRecorder is not running.</span>
2. <span style="color: rgb(0, 0, 0);">Open the folder **C:\\Program Files\\Noldus\\MediaRecorder 6.**</span>
3. <span style="color: rgb(0, 0, 0);">Right-click the file **MediaRecorder.exe** and select **Properties**.</span>
4. <span style="color: rgb(0, 0, 0);">Open the **Compatibility** tab.</span>
5. <span style="color: rgb(0, 0, 0);">Select **Disable display scaling on high DPI settings** and click **Apply**. </span><span style="color: rgb(0, 0, 0);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/ziY6dLx5cHjLK3W0-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/ziY6dLx5cHjLK3W0-image.png)</span>
