Automatically capturing stills from video presentation?

Question

I have a video training course supplied as AVI files. Most of the screens are shown as slides with a pointer moving around on them.I'd like to capture a screenshot of the slide automatically when the screen changes (ignoring when the image changes a small amount due to the pointer moving around.)I want to do this so I can paste the images into a word or html document that I can add notes to as I learn as at the moment I'm taking screenshots but it's very slow and tedious and the course is very long (around 24 hours play time).Can anyone suggest how to go about doing this?

The feature you're looking for is called 'scene detection.' Some video editing software like Premiere and Resolve have this feature included. There's even a command line tool if you're a techie.
