I have a AT-compatible and am interesting in `grasping' video images from a VHS player (or camera) onto the computer's screen. I have been informed about a technique called Gen-Locking (sic.), but don't know of any peripherals available for my type of machine which utilize this technique. I have heard of such a device [dubbed: `Gen-Lock'] for the Amiga, but haven't run across one for AT-type machines. If anyone has any information on Gen-Lock devices or any other type of peripherals that performs the desired task, please leave me E-mail. Thanks in advance.... Steven J.

I think what you want is a frame grabber. Some sort of high speed A to D flash converter. -- ======================================================================= | ...sun!hoptoad!\ Tim Pozar | | >fidogate!pozar Fido: 1:125/406 | | ...lll-winken!/ PaBell: (415) 788-3904 | | USNail: KKSF 77 Maiden Lane San Francisco CA 94108 | =======================================================================

The genlock for the Amiga only affords you the ability to put the VCR image underneath the Amiga's normal image and possibly export this to another VCR. Sort of like a video-titler. To import the VCR's image and place it in computer memory you need either a frame grabber and supplementary software/ hardware to work with it, or you need some sort of a digitizer. Of course, for serious work, your VCR needs to the expensive single-frame stopping kind! Besides, for really serious video work, you probably need to get a quantity of one of this well-known system: an AMIGA {500,1000,2000}. All the peripherals for such video development are available for it and improvements to such systems are rapidly being worked out. ---> "Only AMIGA makes it possible." :-) <--- - Naseer Khan
