VirtualDub is great for this. You open the AVI with it and then select the "in" and "out" points using the time bar and/or buttons on the bottom. Use this to export the video as smaller chunks of data. Remember, AVIs are edited based on what's called a "keyframe" - one frame of film that the frames that come before and after are based on during in encoding. You can get VirtualDub here: http://www.virtualdub.org/ . I don't know if it will work on a Mac, but there's nothing on the downloads page that says it can't, so you might as well give it a shot. Hope it works out!





EDIT: VirtualDub can cut video up based on time, but not based on resultant file size, so you'll have to experiment with how much time = file size. VirtualDub can also re-encode the video in a smaller resolution or in a less-precise format, and this can help you save on file size, but the cutting-up method is easier to get the hang of if you're new to video editing. Also, here's the Wikipedia page on keyframes, which explains them better than I do. http://en.wikipedia.org/wiki/Keyframe
