ABSTRACT:
In order to attain such editing that the fade in/fade out effect is obtained at a joint between scenes, an editing circuit for magnetic recording and reproducing apparatus includes memory for storing therein the last field (or one frame) of a video signal of a first scene recorded on magnetic tape, and operation processing circuit for adding an output signal obtained by repetitively reading out signals from the memory to a video signal of a second scene supplied from outside with proportions sucessively changed. The output signal of the operation processing circuit is supplied to the magnetic tape as a recording signal.
