The original VirtualDub project (http://www.virtualdub.org/) is one of the longest running one man development shows that I'm aware of. Avery Lee, the author states he started it in college and kept updating it up to v1.10.4, released 2013-12-29. Personally, it was one of the first programs I ever used when first I dipped into video editing. All good things come to an end, eventually. Much respect and all the best to him.

[VirtualDub2 is] An enhanced version of the original VirtualDub with improved usability, and extended to work with new formats and plugins. A streamlined video editor with simple frame-by-frame timeline. Free, open-source, portable.
