A script to use gmic to displace adjacent images in a folder and output into a second folder - should work on Linux and Windows ( using git-bash and downloading gmic cli and placing it in the C:\Program Files\Git\usr\bin directory) . Copy script into notepad ++ and save as file with .sh extension. It also handily resizes all images to the same size before operating the gmic function.
#! /bin/bash
#make directory to hold output
h=$(pwd)
echo $h
#make folder to store originals
mkdir $h/originals
mkdir $h/frames
p=$(date +%Y-%m-%d_%H%M%S)
mkdir $p
echo -n "Source image format ? : "
read f
#copy originals to $h/originals
cp *.$f $h/originals/
#randomise
echo -n "Randomise ? (y/n) : "
read rn
if [ $rn == "y" ] || [ $rn == "null" ]
then
find . -maxdepth 1 -name '*.'$f''|while read filename; do echo ${filename}; mv ${filename} ${RANDOM}.$f; done
