VirtualDub
              For Microsoft Windows, Avery Lee created the free and open-source VirtualDub video capture and editing
              tool. Filtering and recompression are both part of its intended use when processing linear video streams. It is
              optimised for quick linear operations over video but lacks the editing power of a general-purpose editor like
              Adobe Premiere. It can be expanded with third-party video filters and offers batch processing capabilities for
              processing lots of files. VirtualDub is primarily designed to work with AVI files, but it can also read (but not
              write) MPEG-1 (MPEG stands for Moving Picture Experts Group) files and handle collections of BMP images.
              A VirtualDub snapshot is shown in Figure 1.2.
