Decomb Plugin

The Decomb package plugin functions for Avisynth provides the means for removing combing artifacts from telecined progressive streams, interlaced streams, and mixtures thereof. Functions can be combined to implement inverse telecine (IVTC) for both NTSC and PAL streams.

The term "combing" is used as a general term versus "interlacing" because interlacing is usually associated with nonprogressive streams. What look like interlacing artifacts can be seen on telecined progressive streams, so I use the term combing to refer to all such artifacts, regardless of the type of the stream.

The package automatically adapts to any telecine/capture patterns, e.g., 3:2 NTSC or 1:1 PAL, and mixtures thereof, although if you want to decimate the recovered progressive stream, you have to specify the desired decimation ratio. The recovery process is completely modeless (patternless) and does not rely on any fixed telecine patterns or phasing. None of the functions introduce a delay in the audio or video streams.
