@anchor{setparams}
@section setparams

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.

@table @option
@item field_mode
Available values are:

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

@item bff
Mark the frame as bottom-field-first.

@item tff
Mark the frame as top-field-first.

@item prog
Mark the frame as progressive.
@end table

@item range
Available values are:

@table @samp
@item auto
Keep the same color range property (default).

@item unspecified, unknown
Mark the frame as unspecified color range.

@item limited, tv, mpeg
Mark the frame as limited range.

@item full, pc, jpeg
Mark the frame as full range.
@end table
@end table

@section showinfo

Show a line containing various information for each input video frame.
