Suggestions for a set up to record video chats, and people in a room at the same time

Hello AppleVis,
I'm posting this forum, because I need some advice or suggestions on recording video calls along side people in a room.
I'm in a group that's pretty much been combined since the groups in the two areas are small. So the video calling will be pretty frequent during the meetings.
We're wanting to record our meetings to format into podcasts.
I'm unsure what specific video calling service will be used. Whether it be Skype, Facetime, Hangouts, or Messenger. However, I'd imagine that those would be the most common.
Any set up advice, software, or hardware advice or suggestions is greatly appreciated.
Chuck
