The 'Movies' Menu of Fraps, in which the recording settings are set.

Fraps is a popular recording software used by LP'ers because it can record movies as well as take screenshots, which are saved to a folder of the users' choice. It displays a small yellow FPS counter in a corner of the game, which turns red when Fraps is recording. These numbers do not show up in the actual movie. However, Fraps is not free and it requires the user to pay for it via PayPal. Despite this requirement, it is one of the most popular softwares in the gaming community (most likely because it has been designed for gamers making game walkthroughs)
