If you are interested in results containing video, Ezy allows you to further refine your search by selecting a specific type of video. 

You can do this through the Content Type section in the Advanced Filtering Panel.
​

Embedded refers to videos hosted by third parties like YouTube or Vimeo. It also covers links to websites that contain video content.
​
​Native refers to videos uploaded directly to the social network.
​
​Live video is currently being played, whereas "was live" means that the publisher broadcasted a video that has ended.
​
You can of course select just "Video" to include everything.
