Avid Systems provide twenty-four tracks for synchronized metadata, linking any digital investigative asset directly to the video evidence. Assets include word processing documents, spreadsheets, e-mail, digital photos or virtually any digital file that can be accessed on a computer. As the video exhibit is played, hotspots on the Avid timeline guide the analyst, investigator, or prosecutor to evidence relevant to that point in the video clip. With the click of a button, the digital asset is launched. The Avid MetaSync system can even link a video sequence to a live Web site, providing dynamic access to covert surveillance cameras.
