To embed a video, go to a place that you can edit text and click on the Panopto icon (green circle) on the editor toolbar. Find your video and select it to insert into the page.
Look here for Panopto's documentation: http://support.panopto.com/documentation
In some cases, the Panopto Recorder tries to save the video in a place that you don't have permission to write a new file. In the Panopto Recorder program, go to Preferences (on the menu bar) and make sure the Recording Folder is set to a location that you can write to.
