Video Recording Hookups

This is from the Championship A-Z list:

Video Recording Hookups: Teams are welcome to record their matches. Please see the Field Supervisor for the location of the Multi AV boxes, which you can connect your audio and video recording devices to. There are a limited amount of Multi AV boxes available, so we ask that you kindly limit recording to the matches that your team is playing in.

Does anyone know what devices will work with this and what type of cables are required? Are there instructions for this anywhere? What video quality do you get?

This is fully speculation.

But, at SBPLI my livestream hookup (presumably the same thing) was through a Blackmagic Atem.

From there I could output it over HDMI, or SDI.

I have an Elgato capture card I will bring if anyone wants to borrow it. Just PM me.
