Hum?

‘interl’
    Set the interlacing mode. It accepts the following values:
    ‘1’        Force interlaced aware scaling.
    ‘0’        Do not apply interlaced scaling.
    ‘-1’        Select interlaced aware scaling depending on whether
the source frames are flagged as interlaced or not.
    Default value is ‘0’.

Maybe the default value should be -1.
