# Reference View pane
The Reference View pane is used to monitor captured videos from the reference cameras. Up to two reference cameras can be monitored on each pane. This pane can be accessed under the *View tab* → *Reference Overlay* or simply by clicking on one of the reference view icons from the main toolbar ([](https://v23.wiki.optitrack.com/index.php?title=File:ToolBar_ReferenceView_20.png)).
Cameras can be set to a reference view from the [Devices pane](/v2.3/motive-ui-panes/devices-pane.md) or by configuring video type to grayscale modes.
## Assets Overlay
In this pane, cameras, markers, and trackable assets can be overlayed over the reference view. This is a good way of monitoring events during the capture. All of the assets and trajectory histories under the Perspective view pane can be overlayed on the reference videos from this pane.
**Note:** that the overlayed assets will not be rendered into exported reference videos.
