MediaTagger is best applied for analysis of events where visual information is important, or where a textual representation of the event by itself is inadequate for mental reconstruction.
Tags can contain free text or a fixed code from a user designed classification system.
This labeling can be done on any number of levels, and levels can be totally independent . The Viewer contains several control options for video play back. Transciption text tags are shown as subtitles, multiple levels of transcription are represented as multiple independent subtitles. Any subset of transcription levels can be enabled to play back as subtitle. Simultaneous occurance of transcription subtitles implies simultaneous occurance of the coded event.
