VirtualDub
What VirtualDub is
VirtualDub is a free Windows utility for video capture and processing, intended as a fast linear pre- or post-processing companion to a general-purpose editor rather than an editor itself. Capture requires a Video for Windows-compatible device and driver, and supports fractional frame rates, optimised disk access, AVI2 and multisegment capture, input-level monitoring, plus real-time downsizing, noise reduction and field swapping. Processing handles AVI2 and multi-segment AVI, MPEG-1 and Motion-JPEG decoding, audio-track removal or replacement, video filters, frame-rate changes and preview with live audio. Batch processing handles large groups of files. The utility mainly targets AVI; it reads but does not write MPEG-1 and can work with BMP image sets. Third-party DLLs add filters and input drivers for more formats. The maker releases source code under the GNU General Public License. The site lists version 1.10.4 as stable. Email reports are accepted, although responses are not guaranteed; incoming messages are limited to 40K raw size.
