I just got Camtasia 9 from the humble bundle and am trying it out with one of my tutorial videos for youtube. Everything seemed fine and I have a pretty good understanding how to use it, so I recorded a 5 hour video with it, and unfortunately, I didnt realize how ridiculously loud my system audio was when I was recording. The sound effects from the computer are like 10 times louder than my microphone. The problem I am having hree is there is only one audio track, for both the microphone and system audio, and adjusting it seems to have no effect on the system audio in the recordings. Is this a common problem? Does anyone know how I can fix this?
