Deinterlace the input video ("yadif" means "yet another deinterlacing
filter").
-It accepts the optional parameters: @var{mode}:@var{parity}:@var{auto}.
+This filter accepts the following options:
+
+@table @option
-@var{mode} specifies the interlacing mode to adopt, accepts one of the
-following values:
+@item mode
+The interlacing mode to adopt, accepts one of the following values:
@table @option
@item 0
Default value is 0.
-@var{parity} specifies the picture field parity assumed for the input
-interlaced video, accepts one of the following values:
+@item parity
+The picture field parity assumed for the input interlaced video, accepts one of
+the following values:
@table @option
@item 0
If interlacing is unknown or decoder does not export this information,
top field first will be assumed.
-@var{auto} specifies if deinterlacer should trust the interlaced flag
-and only deinterlace frames marked as interlaced
+@item auto
+Whether deinterlacer should trust the interlaced flag and only deinterlace
+frames marked as interlaced
@table @option
@item 0
Default value is 0.
