NAME

       atisplit - conversion utility from the GATOS package.

SYNOPSIS

       atisplit

DESCRIPTION

       The  program  atisplit is a small utility to convert gatos capture file
       (gatos.yuv) into a series of yuv frames good for input  to  mpeg_encode
       program.

       mpeg_encode can be obtained on metalab (http://www.metalab.unc.edu/).

       note  that since mpeg_encode uses yuv files with only quarter of cb and
       cr fields the output files have less information than the input one. in
       particular  the total size of the output files should be just below 3/4
       of the size of the input file.

USAGE

       - Start the "TV in a Window" application:
              ./xatitv &
         and capture whatever you want,
              atisplit
         atisplit furiously prints out frames.

       - You must edit the default.lparam file (see below);

       - And,
              mpeg_encode default.lparam
         this produce output.mpg MPEG file.
