Pulldown Filter

Description

The Video Pulldown Filter is used to convert non-interlaced sources to interlaced
targets without interpolation.
The most commonly used pulldown is 3:2 pulldown, used for converting film footage
for playback on NTSC devices. DVD video is for example very often making use of
this method. When your source is 23.976 frames per second progressive and your
target is 29.97 frames per second interlaced, this filter will produce footage following
the 3:2 pulldown rule. However, pulldown might be usefull for more conversions
because it entirely avoids bluring caused by interpolation it will not modify the actual
image data of your source video but rather prepare it for playback on an interlaced
device. Occasionally, depending on your source and target frame rates, stuttering can
happen in the playback. In that case it is recommended to remove this filter and use
interpolated results which is automatically created during conversion.
