NAME

       fieldcomb - combine two or more field frames for video animation

SYNOPSIS

       fieldcomb [ -e|-o ][ -r ] [ -f combined.hdr ] field0.hdr field1.hdr ..

DESCRIPTION

       Fieldcomb  combines  two  or  more  field  frames  into  half  as many final video frames for field-based
       animations.  Normally, the even scanlines in the output are given over to the first, third,  fifth,  etc.
       pictures  given  on  the  input,  and the odd scanlines are given over to the second, fourth, sixth, etc.
       pictures on the input.  This behavior corresponds to the -e option, which is set by default.  To  reverse
       this ordering, the -o option must be specified.

       Normally,  fieldcomb  will name output frames by dividing the numbers on the input field file names by 2,
       inserting a 'C' right before the number, adding leading zeroes  to  make  it  always  four  digits.   For
       example, the command:

         fieldcomb anim12.hdr anim13.hdr anim14.hdr anim15.hdr

       will produce two output pictures:

         animC0006.hdr & animC0007.hdr

       If  an odd number of input files is given on the command line, the last file is held over and used as the
       first file in the next invocation of fieldcomb in the same directory.  In this  way,  the  program  works
       well  with the "TRANSFER" facility of ranimate(1), which does not guarantee an even number of frames will
       be passed every time.

       If only two input files are given, the -f option may be used to specify a different output  name  of  the
       user's choosing.

       If the -r option is specified, then the input files will be removed once they have been combined.
