@item multiple.tff
Cumulative number of frames detected as top field first using multiple-frame detection.
@item single.bff
Cumulative number of frames detected as bottom field first using single-frame detection.
@item multiple.bff
Cumulative number of frames detected as bottom field first using multiple-frame detection.
@item single.progressive
Cumulative number of frames detected as progressive using single-frame detection.
@item multiple.progressive
Cumulative number of frames detected as progressive using multiple-frame detection.
@item single.undetermined
Cumulative number of frames that could not be classified using single-frame detection.
@item multiple.undetermined
Cumulative number of frames that could not be classified using multiple-frame detection.
