When you “insert” video into a page, you are actually linking to a video hosted elsewhere, e.g. YouTube or Vimeo. Video playback is resource-intensive and can bring a webserver to its knees or crash it. Be sure to thoroughly read the fine print on a hosting service before you upload the video, particularly regarding copyright infringement, maximum upload size, subtitles for accessibility compliance, and commercial use.
