Computers can’t understand the analog waves that make up old VHS tapes and pre-DV camcorder videos. These curvy patterns contradict the binary world of “off” or “on,” so you need to digitize those sources before your Mac can “see” the picture. Pinnacle’s Video Capture for Mac is a fin-shaped box that handles this job—and little else. Plug in an analog video source, and the unit translates it into a 640-x-480-pixel MPEG-4 file your Mac can recognize. It works, but armchair archivists will immediately wish it had a few more features beyond its single trick.
