Video Tape Copy Problems and Solution
High Resolution Tape Copy
       with Minimal Loss

Video tapes lose resolution and intensity when copied.  The images become blurry, with a  milky like overlay film.  If copies are made from copies the loss becomes more extreme and courtroom unacceptable.  In order to minimize the loss of information content, resolution and intensity, the video signal must pass through a full frame time base correction unit (a 525 line TBC) with both color and gray scale intensity adjustments.  Furthermore, the signal path used for the copy process should be the SVHS pathway.  The SVHS pathway is wider bandwidth than the VHS pathway and introduces less signal loss.  Only high quality new video tapes should be used in the copy process. The resulting copy will be stable, bright, with good contrast, playable in ordinary VCR units.
