It kind of baffles me. When I record a video with fraps, the raw file is usually 1-3gb. Using VDMod and xvid, I can compress it to 50-100mb with little loss in quality. When the file size is relatively small, however, it's not as effective. For a 10mb 1 minute video I can understand because it can't really get any smaller. But I compressed a 59mb video that I downloaded today and the result was 50mb. What's worse, I cut the video length almost in half, so it actually got larger in size after compression. The original video is in mp4 format like all the other videos I've downloaded, so I have no clue what's causing this problem.
