A method of converting a field of a regenerative signal in a VTR is provided wherein when image is reproduced at a nonstandard play speed, field data of a predetermined field number is formed using an inter-field signal with respect to a still part, and field data of a predetermined number is formed using only an inter-line signal with respect to a moving part; with respect to a carrier chrominance signal of a different field which will be interlaced, a signal processing is performed in such a way that when composite video signals are inputted in a normal direction, a phase is inverted, while when the composite video signals are inputted in a reverse direction, the phase is not inverted; and when abnormality occurs in an input state of the composite video signals, field data of a predetermined field number is formed using only the inter-line signal.
