All these plugins are for Avisynth 2.5+ version. The plugin zip file contains the dll, and documentation without images. Seperate zip files for images and source code are included wherever they exist. This scheme is used as images occupy much of storage. Some may not be interested in source code. However at this site all images are displayed. The dlls can be placed in plugins folder for autoloading. A LoadPlugin call will be needed if the plugin dll is put in any other folder. There are many functions in the ColorIt, TransAll and EffectsMany plugins and as Avisynth has a limit on number of plugins and or functions for autoloading, it may be preferable to keep these plugins in a different folder and invoke loadplugin.

Always the latest version of the filter will be availble at this site. The older versions will be deleted. Clicking under the Filter name column entry transfers to a page wherein a more detailed description of the filter, its usage and examples are depicted. Download is straight from this page by clicking under the download plugin or images or source code column of the table.
