Call me naive, but in my old video editing software (Video Explosion which I think got taken off of the market because of a legal conflict with Vegas- they are almost identical), I could simply insert voice over by plugging in my $19.95 microphone into my pink jack in the back of my computer, hit record and talk and it would record onto the track.
However, I can tell the sound is being picked up because the track meter moves, but it is not saving it or importing it. Any ideas?
