What to look for when buying a video enhancer/processor?
Before purchasing a video enhancer or processor, you should define the problems you want it to address. Sometimes, only moderate processing is needed, such as brightness and image definition control, which may be achieved inexpensively with a simple image enhancer. In other cases, a stronger tool is needed, such as for full color correction, black level control, contrast control and more. The format of operation should also been taken in account: Composite video, Y/C or Component video (analog or digital). Before purchasing a video processor, bear in mind your future needs as well, so the processor will not be made obsolete by your next purchase of equipment.
