Abbreviations:

Named arguments are written as "arg" and are always optional, non-named optional arguments are placed into [] brackets.
The types of the non-clip-arguments can be int (integer), float, string or bool.
[yuy2] etc. denotes the color formats the filter can deal with. See ConvertToRGB / ConvertToYUY2 / ConvertBackToYUY2 for more details.
[v 2.04] denotes the version of AviSynth (above 2.01) since the filter is available.
