ABSTRACT OF THE DISCLOSURE An electronic editing system utilizes time code signals for detecting color frame phase of video signals reproduced by a playback-side video tape recorder and by a recording-side video tape recorder. In order to enable this operation, color subcarrier phases are identified by a frame data of the time code signal during test mode operation. In the editing operation, the color subcarrier phases of the video signals of the playback-side video tape recorder and the recording-side video tape recorders are derived on the basis of the time code signals at editing points. The utilizing the color subcarrier phases identified by locking a color framing pulses of the video signal with a reference synchronizing signal, based on which a reference color frame phase can be derived, detecting difference of phase between the time code signal and the color framing pulse, and detecting difference of phase between the color framing pulse and a color frame phase of the video signal on the video tape.
