When I "stretch" a clip it goes slower. If I "squeeze" a clip it gets faster.

Now, you can "squeeze" a clip to make it go faster and STILL retain the pitch of the singer/speaker/Voice over. So when you say chipmunk do you mean "pitch" or actual speed of the audio? I'm asking 'cos something DOES have to give when "squeezing" or adding a velocity Envelope: EITHER the audio has to increase in pitch OR speed OR both, to "fit" with the Video portion. However, and I did read 4 times your post, you speak of "adding" audio AFTER the video is in place? How did you do that? And why? And then you ask how to slow down the Audio but also speeding up the Video?

I am really confused.
