Hi guys, I have really strange problem, that had me really stressed.
I'll be thankful for any advises, cause I run out of ideas what's wrong.
First - our basic setup includes ATEM Television Studio HD, 4 CANON XF205 cameras and other stuff. Cameras are connected to the switcher by 100 meter SDI cables - Belden 1855A. The setup works really well, even in tough conditions and didn't have any problem so far.
Now comes the funny part - we also have ATEM 1 M/E PS 4K. It always stays in the studio and is working really fine. I decided to install it in our mobile system, cause it has more useful options that we need.
After installing I run few tests in the studio and everything went well, although I didn't use the long cables.
Then we went to broadcast some event and 2 of my cameras started blinking constantly. I tried to change all cables, cameras, inputs, settings...I also checked for internet routers nearby that could cause that. And I found that only inputs 1,3,5 are blinking. The other inputs seemed to work fine. I checked the inputs with the same source and cables. So I thought there is problem with the inputs. But these inputs were working fine with much shorter cables in the studio. Yep, I tries connecting something with short cable and all the inputs were working fine again. Also, I tried connecting one of the cameras to one of the problem inputs using optical cable and two SDI-FIBER converters. There was no problem. So, you could say, the problem is with my cables or their length. But then, why do they work with the other inputs and with the ATEM TVS HD ?
Weird...
p.s. So I had to finish the event using channels 2,4,6,8. They worked fine...but two of them tried to blink for a really short time once or twice. But I can't believe all my cables are bad (since they worked fine week ago). Maybe after all the 1M/E is more sensitive to cable length that the TVS HD?
