How does Google take a video preview if there is no microdata?

Question

Search Engine Optimization

Example:
Search for "nutella fight"

This is what Google showed. At first I thought it was a snippet, I read it and realized that the Video snippet is different (there would be a big picture on top). On the page itself, I also do not find micro- markup https://meduza.io/video/2018/01/26/vo-frantsii-vtr...
Where does this image come from and how to do it?
