A "flipbook" is one of those little books where each page is of consecutive frames, so when you flip throught them, they seem to move like a movie. This effect has worked quite well in various music video's. Here are two softwares that do that in their respective platforms.

For the PC: Flipbook Printer is a free software. There are even some links at the bottom of the page that direct you to other artists who use flipbooks for their work/ art.

For the Mac: Naked Software makes a program called Movie Flipper that can be found at the bottom of this page. On the same page, you will find some other quite interesting video software.

Both these softwares are donationware, so if you use them, please donate.
