An apparatus for processing a video signal to be recorded having a pre-emphasis circuit for pre-emphasizing a signal component with a first predetermined frequency band in the video signal to produce a pre-emphasized video signal, a modulating circuit for frequency modulating a carrier with the pre-emphasized video signal to be recorded, an extracting circuit for extracting a signal component with a second frequency band within the first predetermined frequency band and having a level higher than a threshold level from the video signal, a multiplier for multiplying the outputs of the modulating circuit and the extracting circuit, whereby the amplitude of the frequency modulated signal from the modulating circuit at the portion when the extracted signal is obtained is higher than at the rest of the portion, and a recording amplifier for amplifying the output of the multiplier. Accordingly, the level of the frequency modulated video signal is changed in response to the level of the extracted output signal in the second frequency band, thereby to minimize the deteriorations of frequency characteristic and waveform characteristic of the video signal and to avoid the occurrence of an inversion phenomenon.
