mix 2 analog video sources in 1 video-out signal?


my problem is, I have to analog video cameras. one is positioned underwater in a pool and the second one is above the first one overwater. I would like to grap the upper half of the underwater video signal and the lower half of the overwater video signal and process it to one analog video signal.

Never used my arduino for video processing before. Would this some how be possible?

If not, you need something like this:
