OMF & AAF File Interchange Flashcards
What are the differences between Media/Essence data and Metadata?
Media/Essence data are forms of multimedia data that are essential to a multimedia program, and that can be perceived directly by an audience i.e. audio, video, graphics, etc.
Metadata provides supplementary information about media data.
What is an MXF file?
MXF is a media file format containing actual video and audio media.
How are embedded OMF/AAF sequences different from externally referenced sequences?

Externally referenced sequences result in a single metadata file (.omf or .aaf) and all associated media stored as separate files (similar to the Pro Tools session structure).
