Ok i am gonna be doing some conferences so i need some software that will allow me to capture my screen, but it needs to be able to capture for extended lengths of time. I have found camtasia but it has a 2 gig limit. I need to be able to capture hours at a time. I will be using a camcorder also to film the speaker and once its said and done i want to do a picture in picture effect and run sound through the camcorder using clip on mics and a small board. Then just sync it up and burn it to disc. can you guys suggest anything for me?
