+@section estdif
+
+Deinterlace the input video ("estdif" stands for "Edge Slope
+Tracing Deinterlacing Filter").
+
+Spatial only filter that uses edge slope tracing algorithm
+to interpolate missing lines.
+It accepts the following parameters:
+
+@table @option
+@item mode
+The interlacing mode to adopt. It accepts one of the following values:
+
+@table @option
+@item frame
+Output one frame for each frame.
+@item field
+Output one frame for each field.
+@end table
+
+The default value is @code{field}.
+
+@item parity
+The picture field parity assumed for the input interlaced video. It accepts one
+of the following values:
+
+@table @option
+@item tff
+Assume the top field is first.
+@item bff
+Assume the bottom field is first.
+@item auto
+Enable automatic detection of field parity.
+@end table
+
+The default value is @code{auto}.
+If the interlacing is unknown or the decoder does not export this information,
+top field first will be assumed.
+
+@item deint
+Specify which frames to deinterlace. Accepts one of the following
+values:
+
+@table @option
+@item all
+Deinterlace all frames.
+@item interlaced
+Only deinterlace frames marked as interlaced.
+@end table
+
+The default value is @code{all}.
+
+@item rslope
+Specify the search radius for edge slope tracing. Default value is 1.
+Allowed range is from 1 to 15.
+
+@item redge
+Specify the search radius for best edge matching. Default value is 2.
+Allowed range is from 0 to 15.
+
+@item interp
+Specify the interpolation used. Default is 4-point interpolation. It accepts one
+of the following values:
+
+@table @option
+@item 2p
+Two-point interpolation.
+@item 4p
+Four-point interpolation.
+@item 6p
+Six-point interpolation.
+@end table
+@end table
+
+@subsection Commands
+This filter supports same @ref{commands} as options.
+
+@section exposure
+Adjust exposure of the video stream.
+
+The filter accepts the following options:
+
+@table @option
+@item exposure
+Set the exposure correction in EV. Allowed range is from -3.0 to 3.0 EV
+Default value is 0 EV.
+
+@item black
+Set the black level correction. Allowed range is from -1.0 to 1.0.
+Default value is 0.
