A video recording apparatus of one-inch helical scan type including rotary and stationary drums arranged coaxially, reproducing, recording and erasing magnetic heads arranged equidistantly around the rotary drum in this order viewed in a rotational direction of the rotary drum, and a magnetic tape feeding mechanism for feeding a magnetic tape around the drums along a helical path. By means of the recording head a video signal is recorded on the magnetic tape in such a manner that a video signal of one field is recorded as a single inclined track. The reproducing head is shifted in an axial direction of the drums with respect to the recording head by such an amount that the reproducing and recording heads scan adjacent tracks simultaneously. The apparatus further includes a delay circuit for delaying a video signal reproduced by the reproducing head by 2/3 field period and a mixing amplifier for selectively supplying a delayed video signal to the recording head. Thus, when the delayed video signal is recorded by the recording head, it is recorded on the magnetic tape at the same position where the relevant video signal has been reproduced by the reproducing head. A video signal generated from another VTR, TV camera or character generator is supplied to the recording head via the mixing amplifier and is recorded on the video tape to effect the video editing.
