Default generated AFD values
Default AFD values are generated when the three following conditions are met:
• The AFD output setting in the Configuration Manager is set to Always
• The clip does not have AFD in the data track, and
• The clip does not have AFD specified in its clip properties
Under these conditions, default AFD is generated and inserted, based on ARC performed and the
source material format. Default generated AFD settings are described in the table below.
