Edgar Dubrovskiy Posted October 30, 2010 Share Posted October 30, 2010 Hi guys! Was assisting today on a promo, shot on old-skuuul 1970's cameras, recording onto DV clamshells. And at some point we ran into a very unusual problem - every time you point a camera at a bright light (eg. shining down the lens, silhouetting artist) the monitoring would just shut off - as if there is no signal coming down the BNC, whereas the picture on the electronic viewfinder was ok. So it seemed as if BNC was overloading and just shutting itself. It only happened for like 1-3 seconds - basically as long as the light was really shining down the lens. Tried different clamshells - the problem persisted. Any ideas of what was the technical cause of this? Called the rental house - guys told me that they have never ever encountered a problem like this. Wasn't a big deal - I'm asking more out of curiosity. Thanks!

Premium Member Chris Keth Posted November 3, 2010 Premium Member Share Posted November 3, 2010 Perhaps the ohm rating of your cable is too low and it can't handle a completely overloaded signal? Link to comment Share on other sites More sharing options...
Edgar Dubrovskiy Posted November 3, 2010 Author Share Posted November 3, 2010 Thanks! What would be a normal ohm rating for a bnc? Link to comment Share on other sites More sharing options...
Edgar Dubrovskiy Posted November 4, 2010 Author Share Posted November 4, 2010 (edited) Found it - 50 and 75. 75 for video. BBC uses 50 though... Edited November 4, 2010 by Edgar Dubrovskiy Link to comment Share on other sites More sharing options...
