Tagging a movie as a video helps us differentiate types of content that aren't truly movies.

If you find some content that is for example:

  • a compilation DVD
  • a "best of" DVD
  • a fitness video
  • a compilation of children's programming

Then marking it as a video is the right thing to do. Videos are still searchable and have all of the functionality that regular movies do, it just helps us keep track of them separately.
