I now use lots of BNC cables, and things there are a bit weird. Some cables have moulded on ends that are mechanically terrible and a sideways yank just snaps them off! We have crimped, clamped and moulded to cope with. The pins are different sizes on 75 and 50 Ohm versions but kind of fit. The Chinese ones that have crimped ends seem pretty decent. Cables are very different though. Stiff vs flexible, thin vs thick and frequency response/cable cables are a pain. I get some made up by Canford Audio - UK broadcast supplier, so I I want 40m of 12G capable cable, there is no way I can afford the tooling required to put the connectors on, so I pay them to make them up. 30m, another common length for me is from them too, but 12G will cope with my normal 20m cheaper cables. It makes all the people who wimp on about how audio cables sound better or worse than others look pretty silly. Squirt 12G video down a cable with high attenuation, questionable impedance and a poor frequency response and your kit looks at it and decides to not let you even try! I'm happy with dirt cheap XLRs, but grumble at spending huge amounts of money on a working and tough video one!
 
12G? Yes, on demand. The cameras and switchers can run in HD mode through to HD - or you can do both - for the live switching and streaming, you can set the cameras to send out 1080 HD, and then I also record that format to SD cards. The alternative is to record to SSD hotswappble drives in 12G. The data rate though is crippling. CFast 2 cards and SD cards, but you format a disk and see something like 17 mins in the display, so two cards give half an hour - and the cards are crazy priced. In honesty, three clients asked for Ultra HD this year. The rest didn't actually ask at all. Worse is that if you cut cameras live, you will make mistakes, so my usual system is to record on 3 cameras, and the switched video to SD card. If I mess up, you can then bring in the camera isolated media and repair it. I split this from coolcats Neutrik connector topic
