I have some (silent) dvd's that are recordings of old Super 8 movies - I would like to view them and record audio commentary at the same time, so that in future, anyone can watch the footage with the audio commentary, as a single video&audio file. I have two macs -if necessary- to play back and record audio, but ideally the viewing and recording might be on one machine, so that when video playback is paused, the audio recording is paused too? Perhaps the audio is immediately 'attached' to the video file as it plays? Is this even possible? I'm familiar with Handbrake and reasonably competent on my mac, but I would love some pointers as to what might be the best way to go about this. Thanks!
