More info in here: br arvutiturve.wordpress.com​2011​05​28​kuidas-eraldada-audio-ehk-heli-videost-et-alles-jaaks-ainult-video​ br br VirtualDub is a video captureprocessing utility for 32-bit and 64-bit Windows platforms (98MENT42000XPVista7), licensed under the GNU General Public License (GPL). It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.
