A new Column “People in videos” of Video Content type has been Introduced where you can specify people who are in the Video to be included in Video Metadata.
The column is available when you edit the properties of your Video that you uploaded in Site Asserts library.
See my post on How to add a Video to SharePoint 2013 site
Once you add the names in People In Video column you can view it at the Video View page towards the right.
One of the biggest advantages of this field however is that if you enter someones name in the site Search box and select the scope “Videos”, you will find all videos where this person was added in “People in videos” column.It looks like a Facebook Photo tagging feature.
