Deinterlace the input video ("w3fdif" stands for "Weston 3 Field Deinterlacing Filter").

Based on the process described by Martin Weston for BBC R&D, and implemented based on the de-interlace algorithm written by Jim Easterbrook for BBC R&D, the Weston 3 field deinterlacing filter uses filter coefficients calculated by BBC R&D.

There are two sets of filter coefficients, so called "simple": and "complex". Which set of filter coefficients is used can be set by passing an optional parameter:

filter

Set the interlacing filter coefficients. Accepts one of the following values:

simple

Simple filter coefficient set.

complex

More-complex filter coefficient set.

Default value is complex.

deint

Specify which frames to deinterlace. Accept one of the following values:

all

Deinterlace all frames,

interlaced

Only deinterlace frames marked as interlaced.

Default value is all.
