Twinax video to coax

Hi all,

Bit of a pickle. I have a twinax connection giving video in format NTSC. I need to convert it to a coax plug or any other type of plug that is commonly found on capture cards. From what I gathered online, my approach will be to just connect one of the centre pins of twinax to the shield of the coax and then the other pin of the twinax to the centre pin of the coax. Is this a suitable approach? Is there any other way someone can think of?

Thank you

It depends upon how the twinax is driven.
if it's differentially driven you can't just ground one of the lines.
In general you either need a 75Ω video differential to single-ended transformer, or a 75Ω video differential to single-ended amplifier.

Fairly certain is balanced output
