This filter converts interlaced content that was originally telecine'd from 24 fps (or similar) progressive content. It works approximately like videorate, but with awareness of interlacing. It merges neighboring fields in the input interlaced stream with the goal of minimizing combing artifacts, while keeping the output framerate constant. If it cannot avoid combing artifacts, it will reconstruct the image from a single field. Note that this filter does not autodetect the framerate, but will automatically fixate at 24 fps.
