FIELDCOMB(1) General Commands Manual FIELDCOMB(1)
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 sec-
ond, 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 guar-
antee 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.
