Option to auto remove all periods of silence

[jgt1942]

How about an option to remove video and audio if the silence is greater than xxx seconds? I need an automatic method to remove portions of the recording where the audio and video are silent. I will determine how long the silence is. I do this for my audio recordings using Goldwave but I don't have a solution for video files. Often this reduces the audio recording by 1/3 and I'd like to do the same for a video file.
