The Picture Element may contain either individual VC-3 Compressed Frames using frame-wrapping or a sequence of VC-3 Compressed Frames using clip-wrapping. The MXF Generic Container (GC) is described in SMPTE ST 379-1. VC-3 Coding Units and Compressed Frames are described in SMPTE ST 2019-1. — This standard specifies the Key, the Length and the Value fields of the VC-3 Picture Element. This standard also defines the Essence Container and Compression Label values and the Essence Descriptor.",
