+Force frame parameter for the output video frame.
+
+The @code{setparams} filter marks interlace and color range for the
+output frames. It does not change the input frame, but only sets the
+corresponding property, which affects how the frame is treated by
+filters/encoders.

+@item auto
+Keep the same field property (default).
