Abstract
A method of processing video signals for eliminating vertical picture fluctuations caused when a video tape recorder reproduces video signals at a tape speed different from that used for recording the video signals. The vertical picture fluctuations are eliminated by substituting distorted vertical synchronous signals for the original vertical synchronous signal, the distorted vertical synchronous signals generated by a processing apparatus having a correction circuit which corrects for the difference in frequency characteristics between the video signal path and the vertical synchronous signal path.
