Genlock and semi professional cameras	Can't Post

I find myself before the impossible task of finding a semi professional digital videocamera with genlock possibility, during recording. someone mentioned there are devices you can put inbetween cameras to synchronize.
I asked Sony and Canon about Genlock possibilities of their respective cameras VX2000 and DM-XL1, but they could not give me a straight answer.
Would you know if anything like this is possible, eventually with a genlock device inbetween?
The purpose is to be able to monitor very fast movements (inkdrops from a dedicated inkjet system) for which the exact frame time can be pulsed externally.
I know there are cameras (without recorder) that do this, but I have to invest in a general purpose, 3CCD digital camera with firewire in/out)
if you do not know, could you give me any links where to look for an answer?

Re: Genlock and semi professional cameras	Can't Post

My knowledge of genlock is that the video synchronization of the camera can be locked to external synchronizing pulses. This is usually only found in industrial and broadcast equipment. The external device you may be thinking of is called a digital frame synchronizer. The video from the camera is fed into it, digitized and stored--usually up to a frame and a half or so of video. The stored digital information is then converted back to a video signal and outputted. The output can be genlocked to an external synchronizing pulse. Broadcasting companies use them all the time to genlock remote sources such as satellite feeds. A version of that is also used to convert from one video standard to another. While the prices have gone down recently, the good quality frame synchronizers can be rather pricey.
