It's not entirely hopeless...I tried the following and it appears to work...
I created 4 .jpg files named 1.jpg through 4.jpg, containing the equivalent number. I then executed the following commands in sequence: touch num.mpeg convert -delay 0 num.mpeg 1.jpg num.mpeg convert -delay 0 num.mpeg 2.jpg num.mpeg convert -delay 0 num.mpeg 3.jpg num.mpeg convert -delay 0 num.mpeg 4.jpg num.mpeg convert -delay 0 num.mpeg 1.jpg num.mpeg convert -delay 0 num.mpeg 2.jpg num.mpeg convert -delay 0 num.mpeg 3.jpg num.mpeg convert -delay 0 num.mpeg 4.jpg num.mpeg convert -delay 20 num.mpeg num.mpeg You can see the files at http://trilug.org/~william/convert basically I think this can be made to work as I indicated below...see revised code: #!/usr/bin/perl #----- use strict; my $convert = `which convert`; chomp($convert); # change to suit your needs my $input_dir = "/home/william/convert"; my $output_dir = "/home/william/public_html/convert"; my $frame_delay = 20; my $output_file = "output.mpeg"; my @input_files = map { chomp($_); $_; } `/bin/ls $input_dir`; foreach my $file (@input_files) { `mv $input_dir/$file $output_dir`; `$convert -delay 0 $output_dir/$output_file $output_dir/$file \ $output_dir/$output_file`; unlink("$output_dir/$file"); } `$convert -delay $frame_delay $output_dir/$output_file \ $output_dir/$output_file`; #----- to join multiple mpeg files, I think you should be able to do the following: convert -delay 0 *.mpeg out.mpeg HTH!
