For JPEG 2000 essence, the MXF input format module currently uses the value of byte 14 of the essence container UL to determine whether the J2K essence is clip- (byte 14 is 0x02) or frame-wrapped (byte 14 is 0x01). Otherwise it assumes an unknown wrapping. Additional wrappings are documented in SMPTE ST422:2019: 0x03: Interlaced Frame, 1 field/KLV 0x04: Interlaced Frame, 2 fields/KLV 0x05: Field-wrapped Picture Element 0x06: Frame-wrapped Picture Element And these should also be handled as frame wrapped content.
