Fraps is a video capture program that we can use to create movies from any website. Fraps cannot compress because there is not enough available time to record the video and codify at the same time. That is why many Fraps video files are too big, mainly if you record them with high resolution. Usually, the Fraps files are in AVI formats after recording a video. So it means the file will be big, to compress Fraps video, you can use a video converter to solve your size file problems.
