What I loved first about Xvid had to do with its amazing ability to compress HOURS of video without going over the dreaded 2-GB file size limit for the video portion of an AVI (a limitation imposed by the AVI specification) that CamStudio has to operate under, since it records using the AVI container format.

The Problem: I had been receiving requests for information for months by educators and lecturers to show how to make extended recordings of their presentations to share online with their classes, and had been stymied. The longest ones that CamStudio Lossless or Lagarith Lossless could get out at 1280X720 were just over 1/2 an hour.
