I have minimal video experience and wanted to consult the video Gods for a small project I have. Here's what I have in mind. I am hosting a small event between 100-500 people. My budget is about $3,000 and I still have about four months till the event. I want to have two stationary and one roving camera feeding live footage into livid union. Then up to two video projectors. As you may have noticed I probably have a lot of gaps in between equipment. Thats where I need help. Right now the only equipment I have is a canon xha1 camera and a mac g5 dual 1.8. I am planning on purchasing livid union with the midi controller on a later date(possibly an edirol four channel video mixer)(?). I am planning on renting everything else to keep within my budget. I would want all cameras to be wireless so what type of interface(s) would I need.
