Do you need quick capture and encoding capabilities for video on your desktop? VirtualDub is a free, Open Source solution specifically designed for that purpose. VirtualDub might lack the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video in return. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters.
