First click on the video you would like to link to, and underneath the video viewing window, click on Share
Next, click on "Link" and find the Record URL and click the Copy button to copy this link. The link will look something like this https://go.openathens.net/redirector/matc.edu?url= https%3a%2f%2ffod.infobase.com%2fPortalPlaylists.aspx%3fwID%3d102572%26xtid%3d168531.
Each segment has its own URL, so you can link to the whole video, or just to a particular segment of a video.
When you click on the title for a particular segment, you will see the link to the full video, and a link to just the segment under "Link."
