# if no file names are supplied a default set of inputs is used (see the

# One line is printed for each HB run. It has the input dimensions,
# output dimensions, crop, PAR, filename & options for the encode.
# Since PAR is only output for anamorphic encodes, an omitted PAR
# is indicated by "1:1" (to distinguish it from the explicit PAR "1/1").
