Blip.TV allows users to upload videos of various formats, sizes, and qualities. These options will allow the administrator to choose the default video formats to display. Blip.TV uses 'tags' to determine this, such as 'Web' for a standard web resolution, and 'HDTV' for a high definition. If you select a tag, then the video format provided by Blip.TV for that tag will be displayed. If you select 'Override tag', then you may specify that the first available video of the given format will be displayed instead, which may or may not have your desired resolution. If a tag or format is not available for a specific video, the module will display the Flash video format instead, which is always present.
