fieldmerge(6D)

NAME
     fieldmerge - merge two field images into one frame

SYNOPSIS
     fieldmerge inimage0 inimage1 outimage

DESCRIPTION
     Standard NTSC Video displays 30 frames per second.  Each frame is
     composed of two fields that are interlaced.  When recording video
     animations it is sometimes good to record 60 fields per second, but to do
     this two fields must be merged together into a single frame by
     interleaving scanlines from two images. fieldmerge interleaves two images
     in this way.

NOTE
     This program requires that all the source images on the command line have
     the same x/y size.
