Video enhancements allow you to add video content to your app, be it from YouTube, Vimeo, or a private server.
The Tracking Name is an arbitrary name, not visible to end users, that you can use to track the performance of this particular link, as well as to auto-fill future instances of this same link.
For the Video URL, you can enter a URL from either YouTube or Vimeo, or simply a link to a hosted video (which must be in .mov, .mp4, .mv4, or .3gp format). Example: http://vimeo.com/55889231
No Repeat simply means that this video link will not repeat in the same place on future pages. If you would like it to, click it for a drop-down menu that allows you to select from the options "All Pages," "All Except," and "Every Other" (each taking effect from the current page forward, not in reverse).
Tap Trigger means that the video must be tapped to be activated. You can toggle this option to "Auto Trigger," which means the link will load automatically when the end user reaches this page.
Overlay refers to the size of the video as it appears on your end user's device. "Overlay" means it will appear in a compact form on top of your content; "Full Screen" means the video will open in its own full-screen viewer, and that your content will reappear once the end user taps out of the video.
Editorial means that the video is editorial-related; toggling to "Ad" means it is advertising-related. This distinction is not visible to end users and is simply for your private tracking purposes in MAZ Stats.
