I just recently discovered AutoIt and have my first script below. It uses the program Image Grabber to extract images from all the .avi files in a directory. Below are two images that should help visualize the process. http://i27.tinypic.com/opr7cx.png http://i26.tinypic.com/288m3qc.png All seems to be okay except that the strings seem to change cases occasionally as shown below. I'm not touching the keyboard during the process at all if that rules out anything. http://i27.tinypic.com/dwbep
