# Configure a video input source

Captured video sources don't usually need configuration, but you can change some of the video settings using the Admin panel, including:

- Configure a video input source

- SDI video settings

Pearl Nano does not support USB video input, so USB video and web camera settings do not apply.

**Open the configuration page for an input source using the Admin panel**

- Log in to the Admin panel as **admin**.

- Ensure a source is connected to the input port,

- From the Inputs menu, click the **source name**. The configuration page for the source opens.

**Video settings**

| **Value** | **Input type** | **Description** |
| --- | --- | --- |
| Scaling (Pearl Nano) | HDMI, DVI, SDI | Use this setting to scale the video input source. This is useful when adding multiple video sources in a custom layout such as picture in picture or side-by-side. The frame size selected for the video source is also what gets sent out the HDMI OUT port when you select the video input as the output source. |
| Image | HDMI, DVI, SDI | This menu allows you to choose a custom no-signal image for the channel. The drop-down list gives you the option to choose the default image or any image you have uploaded through the Add a custom No Signal image |
| Timeout | HDMI, DVI, SDI | The timeout represents the number of seconds after losing the signal that the no-signal is displayed. You may change this number to adjust how soon you wish the no-signal image to appear after the signal disappears. |
