I've been offered a job to shoot a ceremony that requires me to record the event as well as display what I'm shooting simultaneously on a big screen. What do I need to do this? I have an A1-XH and also have experience shooting events, but am not sure what kinds of cables/connections I need to hook up my camera to the screen. Is it possible to record and output my camera at the same time? Do I need to be shooting in 4:3 or does it depend on the screen?
