A media editing system provides an editor with full visibility and editing capability for synchronous data that is adjunct to audio and video. The data tracks include one or more streams of data packets, each stream being of a particular data type. Synchronous data tracks are displayed on the timeline, facilitating data track editing independent of the associated media tracks. The UI also enables selective playback and export of the data tracks along with the corresponding video and audio. The system also enables data streams to be filtered and combined. Data from the data tracks can be extracted and imported into a media asset management system, enabling the data to be searched.
