If I could ask one more thing. If I’ve taken, for example, a 5-minute video, got rid of the parts I don’t need, so I’m left with, say, 1 minute, why is it that when I then open the audio in Sound Forge the whole, original 5-minute audio track is there. It would seem to make editing/saving much quicker if only what was left was imported into SF, rather than the whole thing.
