A video tape editing apparatus for use with first and second video playback devices and a video recording device allows effective editing of homemade video tapes which produces clean, professional transitions of the edit-points. The editing apparatus includes a fade control circuit having a fade selector switch for generating a fade-out control signal to shunt the composite video signal components in a video amplifier when the fade switch is in a first position and for generating a fade-in control signal to remove the shunting of the composite video signal components in the video amplifier when the fade switch is in a second position.

DETAILED DESCRIPTION Accordingly, it is a general object of the present invention to provide an improved video tape editing apparatus which is relatively simple and economical to manufacture and assemble, but has been traditionally unavailable.
It is an object of the present invention to provide an improved video tape editing apparatus which allows effective editing of homemade video tapes without the complication and expense of the usual professional editing equipment.
It is another object of the present invention to provide a video tape editing apparatus for use with first and second video playback devices and a video recording device to produce clean, professional transitions at edit-points.
It is still another object of the present invention to provide an improved video tape editing apparatus which includes a fade control circuit for causing automatically video and audio fade out and fade in edits upon depression of an auto-fade button.
It is yet still another object of the present invention to provide an improved video tape editing apparatus which includes a fade control circuit having a fade selector switch for generating a fade-out control signal when the fade switch is in a first position and for generating a fade-in control signal when the fade switch is in a second position.
In accordance with these aims and objectives, the present invention is concerned with the provision of a video tape editing apparatus for use with first and second video playback devices and a video recording device to produce clean, professional transitions at edit-points which includes a first input connectible to the first video playback device for receiving a first source of composite video signal components and audio signal components, a second input connectible to the second video playback device for receiving a second source of composite video signal components and audio signal components, and a selector switch for selectively switching between the first input and the second input.
A first video amplifier is coupled to the selector switch and is responsive to the composite video signal components for generating a first amplified video signal
