so i am doing video recording for a small church. i found a software(thanks to the people that posted to my other message) that will allow me to have 4 video sources. so now i am trying to find out how can i connect the cameras to my macbook to be able to assign them the right number. i have two HD 120gighd sony camcorders. and one HD mini dv sony camcorder. these are the ones that i need to connect. is there a hardware component that i need to buy? thanks a lot for all the help.
