I dump frames from a gnuplot script as jpg
then use ffmpeg

You need to get all the frame filenames in a
easily readable format.

jpg2frame
====
#!/bin/sh
#set -x
i=1

for j in `ls *jpg`
do
  i=`expr $i + 1`
  nfname=`printf "%06d.jpg" $i`
  echo $nfname
  ln -s $j $nfname
done

jpg2movie
===
#!/bin/bash

echo $#

if [ $# -lt 1 ]
then
  echo "usage: $0 movieFileName"
fi

# -r rate in HZ
# -b bandwidth which controls quality.

ffmpeg \
 -r 10 \
 -b 4000 \
 -i '%06d.jpg' \
 $1
