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.
