SMPTE 407M – Television – Material Exchange Format (MXF) – Operational Patterns 3a and 3b

This standard defines operational patterns 3a and 3b as defined in SMPTE 377M section 7 for the exchangeof MXF files that represent the following levels of file complexity:

–OP3a: A material package that plays out an edit list from one or more file packages where only a singlefile package may be referenced at any given position on any material package timeline.

–OP3b: A material package that plays out an edit list from two or more file packages each of which maybe referenced and synchronized at any given position along the material package timeline.

In each case, a top-level file package is linked to an essence container where each essence container maycomprise either a single essence element or an interleave of multiple essence elements. Furthermore, in eachcase, one or more of the essence containers may be internal or external to the file.

This standard defines the operating restrictions, structural metadata objects, and individual attributes thatshall be applied to the MXF file format specification to achieve interoperability when exchanging an MXF filewith these operational patterns.

These operational patterns require the use of body partitions for internal essence containers. Subdivision ofeach essence container by using body partitions is optional.
