VSDC video editor: change speed of multiple layers

[pdxlion]

Hi all, I'm quite a noob, be gentle with me. I'm trying to stretch an edited video out by 10 seconds. I've got tons of small clips in it, in many layers, precisely placed in relation to each other, so it would be very time consuming to go into each small section and increase the speed a tiny percentage to fiddle with it, to get the timing exact. Is there a way that I can get it to include all layers and say, essentially, "make the whole thing take 3 minutes and 25 seconds instead of what it is now, 3 minutes and 15 seconds". Thanks in advance.

All you need to do is extend a few shots or titles by a second or two. That's the first thing I'd try.

Also, since shorter is generally better, do you really need the extra ten seconds?
