    thanks for sharing this tip! I bought a pyxis this week and never used SDI before, can you tell me what SDI cable should I buy??

      I would buy a cable from an established brand in terms of the cinema world. Like shape, wooden camera, arri etc. Rather spend an extra dollar or two on quality that will last long. And if you find one that is shielded, that’s even better in terms of safety :)

      Yeah, 100%. Not everyone thinks like that unfortunately and cheap out on cables etc :p

    Will all SDI isolator cables work with the PYXIS

      Hi, thanks for the comment. In theory yes. But I was reading up on those cables and solutions and found that those products doesn’t really give you a 100% coverage anyway. But yeah. :)

      @@ghospod well, an extra layer of protection is never wrong, I see no harm in it, with that said tho, good routines and well looked after equipment does it for me. I’m not using the extra protection:)

    I saw one RUclipsr mention that you have to follow the same protocol when using USB-C to HDMI Cables. That can't be correct is it?

    • @AlexReinholdsson
      @AlexReinholdsson  Месяц назад

      Never heard of that to be honest, it’s always good either way routines of course but I never heard of a fried usb c. With that said tho, there is always a possibility but I wouldn’t worry about that personally:)

      The randomness of the problem can be explained by understanding how it happens. The center pin of the cable makes contact with the connector before the ground (outer jacket), then you have a significant chance of frying the SDI. You cannot fry the SDI if your ground circuit is always completed first. With connectors like HDMI and USBC the outer casing of the actual connector is grounded and if you have ever noticed you have to insert these cables a significant distance into the connector before the remaining contacts make a connection. Long story short it's almost impossible to have the powered pins contact the connector before it makes a ground thus preventing the ground fault.
      I would clarify one point that I don't see on all the videos. You do NOT need to disconnect both ends of the BNC cable to protect yourself. There is a concept know as "air gapping". As long as one side of the cable is not connected it's impossible to fry your SDI. That could be important and in our case it's very difficult to disconnect the SDI on the camera side because of the rigging. There is no need though, we simply disconnect the monitor side.

      @ comprehensive comment and I see where you’re coming from. Great one, this video is just a worst case scenario and people really do need to know their protocol, if not to protect the camera but also be efficient on set and to know it if someone says to perform it by the protocol way.
      But yeah, I don’t disconnect the monitor, only the camera, but that’s also due to rigging :)
