Guide about the VirtualDub video editing software

TIP: VirtualDub video software

There is plenty of programs for editing of video files. Yet none of them can match the efficiency combined with simplicity of VirtualDub, a popular software used by many users for more than 15 years already. Our overview will show your how to easily edit, repair, split or merge your video files with this application.

About VirtualDub

The program was originally created by Avery Lee, who wanted to comfortably edit his favorite series. Because of its simplicity and because of all functions are accessible through menus in main toolbar, it started to quickly spread between common users, who didn't have time to learn how to use professional programs.

You can download the program through its main page, which links you to its Sourceforge location, where you can choose between a 32bit or 64bit version and download it for free. The program itself doesn't require installation and you can use it just after the extraction from the downloaded archive. But you should probably put it in its own folder, where you can easily find and access it.
