+@section mcdeint
+
+Apply motion-compensation deinterlacing.
+
+It needs one field per frame as input and must thus be used together
+with yadif=1/3 or equivalent.
+
+This filter accepts the following options:
+@table @option
+@item mode
+Set the deinterlacing mode.
+
+It accepts one of the following values:
+@table @samp
+@item fast
+@item medium
+@item slow
+use iterative motion estimation
+@item extra_slow
+like @samp{slow}, but use multiple reference frames.
+@end table
+Default value is @samp{fast}.
+
+@item parity
+Set the picture field parity assumed for the input video. It must be
+one of the following values:
+
+@table @samp
+@item 0, tff
+assume top field first
+@item 1, bff
+assume bottom field first
+@end table
+
+Default value is @samp{bff}.
+
+@item qp
+Set per-block quantization parameter (QP) used by the internal
+encoder.
+
+Higher values should result in a smoother motion vector field but less
+optimal individual vectors. Default value is 1.
+@end table
+
 @section mp
 
 Apply an MPlayer filter to the input video.
