COLOR VIDEO SIGNAL REPRODUCING APPARATUS ABSTRACT OF THE DISCLOSURE A color video signal reproducing apparatus, such as a VTR, is capable of being operated in a normal speed reproduction mode, as well as in non-normal modes such as stop motion, slow motion, and fast motion. A rotary pick-up head on the apparatus is mounted, e.g., on a bi- morph leaf, for helical and transverse motion so as to scan recorded tracks accurately when the apparatus is in a non-normal mode. A first time base corrector processes the reproduced color video signal in composite form to provide a first corrected composite color video signal. A second time base corrector, formed of a Y/C separator for separating the composite video signal into its luminance and chrominance components, a luminance time base corrector unit for correcting time base errors in the separated luminance component, a chrominance time base comparator unit for correcting time base errors in the separated chrominance component and adjusting the phase of the color subcarrier thereof for standard color framing, and a combining circuit forms a second corrected composite color video signal. A speed detecting circuit, which can include a window comparator, detects whether the record medium is being transported at normal speed, and an electronic switch selects the first and second corrected composite color video signal depending upon whether the speed detecting circuit indicates a normal speed or a non-normal speed, respectively. -i-
