@ -2723,6 +2723,21 @@ detc filter, and should be used with MEncoder but not with MPlayer.
As with detc, you must specify the correct output framerate (-ofps
23.976) when using MEncoder.
.TP
.B "pullup"
Third-generation pulldown reversal (inverse telecine) filter,
capable of handling mixed hard-telecine, 24 fps progressive, and 30
fps progressive content.
The pullup filter is designed to be much more robust than detc or
ivtc, but it is still under development.
No configuration options are available yet.
As the underlying pulldown reversal engine is designed to take
advantage of the new features in MPlayer G2, the current
implementation in G1 is meant to serve mainly as a testbed.
Note: presently pullup lacks any way to cap the output framerate, so
during 30 fps progressive sequences or stills, it will output more
than 24 fps, meaning you'll have trouble if you use it with mencoder
-ofps 23.976.
.TP
.B "softpulldown"
This filter works only correct with MEncoder and acts on the MPEG2 flags
used for soft 3:2 pulldown (soft telecine).
