ABSTRACT OF THE DISCLOSURE A video signal recording apparatus for recording, a video signal on a magnetic tape includes an oscillator which generates an oscillation signal; a variable frequency divider for frequency dividing the oscillation signal; a control cir- cuit for controlling the frequency-dividing ratio of the varia- ble frequency divider in accordance with the speed of advance- ment of the magnetic tape during the recording operatior; a fre- quency divider for generating a plurality of synchronizing sig- nals in response to the output of the variable frequency divider; a camera including an image transducer from which the video sig- nal is obtained in correspondence to incident light from an ob- ject image projected on the image transducer, and a transmission device for transmitting the signal from the image transducer at a rate determined by the synchronizing signals; and a recording section including a processing circuit for separately processing the luminance and chrominance components of the transmitted video signal, and at least one transducer for recording the processed video signal on the magnetic tape in response to the synchronizing signals, wherein the video signal is always recorded on the mag- netic tape in the same format regardless of the speed of advance- ment of the magnetic tape during the recording operation.
