FFF. Mask Module Recommendations

This module is used to specify the subtraction parameters. The number of items depends on the number of Subtractions to be encoded. Typically, in case of AVG_SUB, the number of items is at least the number of ranges of contrast frames to be subtracted from a different mask.
