VirtualDub filters
VirtualDub filters can be loaded manually by clicking on the Load button that appears in the Add Filters dialog box.  They can also be automatically loaded at startup if you copy the .vdf file into aplugins subdirectory under the VirtualDub program directory.  It is possible, although unusual, for filters to conflict with each other, so if you have problems with a particular filter chain you might want to try testing each filter individually to narrow the scope of the problem.
Description: Applies Sub Station Alpha v2.x/4.x scripts to video.
Pretty self-explanatory; handles most of the common features in SSA scripts.  It has text antialiasing, so your subtitles look good at small sizes.
Description: Sharpens images by warping pixels toward edges.

Sharpens images through warping rather than convolution.  Most effective on cartoon-style animation.
Note: This filter won't work in Avisynth because it uses the BitBlt() function from VirtualDub -- Donald Graft has a version on his site which will work.

What is VirtualDub?
VirtualDub is a video capture/processing utility for 32-bit and 64-bit Windows platforms (98/ME/NT4/2000/XP/Vista/7), 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.
I basically started VirtualDub in college to do some quick capture-and-encoding that I wanted done; from there it's basically grown into a more general utility that can trim and clean up video before exporting to tape or processing with another program.  I released it on the web and others found it useful, so I've been tinkering around with its code ever since.
