In a video recording apparatus, a frequency folding information inserting circuit comprises an E/O field detector for detecting whether the present video signal is of an even number or odd number field, a frequency folding information generator for generating frequency folding information representing the state of frequency folding according to the detected result of the E/O field detector, an adder for adding the folded video signal to the frequency folding information, and a position setter connected between the adder and the frequency folding information generator for supplying the generated frequency folding information to the adder at any arbitrary time. In a video reproducing apparatus, a frequency folding information separating circuit comprises a position detector for detecting the position where frequency folding information is inserted in the reproduced video signal, and a frequency folding information separator for separating the frequency folding information included in the reproduced video signal according to the detected result of the position detector.
