File transfer AFD priority
1 AFD from the MXF or GXF metadata is copied to the K2 clip properties.
2 If the MXF stream contains an ancillary data track with AFD ancillary data packets and
Active Format Descriptor attribute of the Generic Picture Essence descriptor in the MXF
header metadata is absent, then the AFD value for the K2 clip is derived from the AFD
ancillary data packet located around 2 seconds into the material. That AFD value is then
copied to the K2 clip properties.
