VirtualDub is a video capture / processing utility for 32-bit Windows platforms, 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. It is mainly geared toward processing AVI files, although it can read MPEG-1 and also handle sets of BMP images.

Features:

• Fractional frame rates. Don't settle for 29 or 30 when you want 29.97.
• Optimized disk access for more consistent hard disk usage.
• Create AVI2 (OpenDML) files to break the AVI 2GB barrier and multiple files to break the FAT32 4GB limit.
• Integrated volume meter and histogram for input level monitoring.
• Real-time downsizing, noise reduction, and field swapping.
• Verbose monitoring, including compression levels, CPU usage, and free disk space.
• Access hidden video formats your capture card may support but not have a setting for, such as 352x480.
• Keyboard and mouse shortcuts for faster operation. To capture, just hit F6.
• Clean interface layout: caption, menu bar, info panel, status bar.
• Reads and writes AVI2 (OpenDML) and multi-segment AVI clips.
• Integrated MPEG-1 and Motion-JPEG decoders.
• Remove and replace audio tracks without touching the video.
• Extensive video filter set, including blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace, and threshold.
• Bilinear and bicubic resampling -- no blocky resizes or rotates here.
• Decompress and recompress both audio and video.
• Remove segments of a video clip and save the rest, without recompressing.
• Adjust frame rate, decimate frames, and 3:2 pulldown removal.
• Preview the results, with live audio.
• Open video file (Ctrl-O).
• Save AVI (F7).
