Zusammenfassung:	PURPOSE:To automatically correct a relative delay time difference between a brightness signal and a chrominance signal in a reproduction system by record ing a low frequency conversion chrominance signal regulating a phase of the low frequency conversion chrominance carrier with respect to a video synchroniz ing signal in a recording system. CONSTITUTION:The device is provided with a frequency conversion circuit 6 converting a chrominance signal of an input video signal into a low frequency conversion chrominance signal of a low frequency conversion chrominance carrier having a prescribed phase relation with respect to a synchronizing signal of the input video signal, a mixer 13 mixing a brightness signal of the input video signal with a low frequency conversion chrominance signal from a chrominance signal low frequency conversion means, and a magnetic head 15 recording a recording signal mixing the brightness signal and the low frequency conversion chrominance signal by the mixer 13 onto a magnetic tape 14.
