Besides using the ss parameter to select a particular frame from the video, you can also use a filter.  
The “Thumbnail” filter selects the most representative frame in a given sequence of consecutive frames 
automatically from the video and saves it as the thumbnail image.

You can use the “Thumbnail” filter by specifying the filter name in the filter() function following input():
