I'm using Movie Studio Platinum. Is it possible to invert the direction of the fades at both ends of an envelope? So instead of going from silent to X decibels, and then back to silent, it goes from full volume to X decibels, and then back to full volume. Splitting the envelope into three, and then fading the envelopes at each end, won't allow me to have a smooth transition if the middle envelope is quieter, but not silent (shown below).
Hope that's clear. Please ask me to explain again if it isn't.
