Telemundo about three or four years ago did an all iPhone/iPad newscast (save for the studio cameras) as a test case. Every story that day was shot and edited on iPhones and iPads. It was quite successful and there wasn’t much difference quality wise. I don’t think they used it to go live though.
I will add I have seen these MMJ kits or just the phone and headphones used in breaking news live shots on the network. I remember when steam pipes exploded in NYC few years back trucks couldn’t get close to safety but the reporters could and used LiveU for special reports.
Don’t let anyone treat you like you’re a VO/SOT when you’re a PKG.
