VIRTUALDUB

VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), 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.

There are lots of programs that let you "edit" video.  And yet, they're frustratingly complex for some of the simplest tasks.  VirtualDub isn't an editor application; it's a pre- and post-processor that works as a valuable companion to one:

  -  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.

You can take a captured clip, trim the ends, clean up some of the noise, convert it to the proper frame size, and write out a better one.  Don't see a video filter you want?  Write your own, with the filter SDK.
