Enhanced capture, management and distribution of live presentations
Techniques are provided for converting live presentations into electronic media and managing captured media assets for distribution. An exemplary system includes capture devices that capture media assets of live presentations comprising a session, including image data of sequentially presented visual aids accompanying the live presentations and audio data. Each capture device has an interface for real-time image data marking of the image data for identification of individual images and session marking of the image data for demarcation of individual presentations of the session. A centralized device processes the captured media assets and automatically divides the captured media assets into discrete files associated with the individual presentations based on the session markings. An administrative tool manages the processed media assets to produce modified presentations and enables modification of the visual aid images identified by the image data markings. A production device formats the modified presentations for distribution on distribution media.
