I have installed Advanced Scene Switcher and I want to automatically stop recording when there is no volume for 60 seconds. Also, if it is possible, pause the recording after say 20 seconds and if the volume is still below this level for more than 60 seconds, stop the recording. I'm recording home movies and I don't know how long they are or I would use the timer. I don't want to have to sit here and monitor them for HOURS. Thank you in advance.
