Forgive me if this is the wrong forum, but here's my situation; I'm going to be shooting backgrounds this weekend to be used later for model shoots. We'll shoot the models in front of green screen, but I was wondering if we can have our backgrounds up on a monitor (or computer screen) and composite our models over them before we take the pictures and video.
I'm shooting with a 5D Mark III. We'll be doing stills and video. I'm a total noob at this kinda thing but wanted to know if it can be done?
I know there are software packages that let you do this kind of thing ...the camera is connected by firewire or USB cable to a computer where you can see the composited effect live. Years and years ago there was one called Visual Communicator but I'd be very surprised if that oldy is still around. So I would look at software "switching" applications designed to allow you to connect multiple cameras and switch between them to produce a live feed. Often those had elements you could key such as lower thirds and backgrounds....also google virtual sets and see what you come up with.
Have you looked into Magic Lantern the nightly builds? With the 14-bit RAW and a fast (expensive) flash cards, you can record in amazing quality using 14-bit raw. I say this so that you record both your backgrounds and then your models using 14-bit RAW.. it will provide amazing green screen editing!
