 Sometimes we have created ROIs in one video, saved them, and opened up a second video to start drawing new ROIs on this second video. Now we may want to replicate the ROIs on the first video on the second video, and we can do this with the `Apply shapes from another video` sub-menu. 
 
 1. To duplicate the ROI shapes already defined in a different video on the current video, navigate to the `Select video` dropdown menu in the `Apply shapes from another video` menu. This dropdown menu will show the videos in your SimBA project that has defined ROIs. 
 
 2. In this dropdown menu, select the video which has the ROIs you wish to replicate. Once selected, click `Apply`. The ROIs from the video in the `Select video` dropdown menu will appear on the frame.
