Hi I am a freelance videographer and I have been asked to film a live event using 2 camera angles, make a multi camera edit and stream the result Live in a webcast.
I have filmed events for this cliant before but not live and I have no experience with streaming.
Could you help me to figure out what equipment I would need and what my set up should look like?
At the moment I have two Nikon d750 cameras which have built in wifi would it be possible to use a portable 4G router to stream HD footage from the two cameras into fcpx and make a live multi cam edit and broadcast it direct to youtube streaming ?
You can't use FCPX as a live switcher, if by "live" you mean in real time, as the event is unfolding. You would need a video switcher, either one purely hardware-based, like the Newtek Tricaster, (an all-in-one solution), or the crop of hybrid hardware/software switchers like the Black Magic ATEM, which borrows your editing computer and couples it to a hardware break-out or interface unit.
But if this is a one-off event, seriously, what a pro does is rent a switcher (an entire portable set-up for doing this is called a "fly-away package") and connect that to whatever device you desire for the streaming. You bill the client for the rental, plus a markup.
