It took me half-a-minute to figure out where it was you meant to click Nat, if you would have said "right click on the F" I would have figured it out a second quicker. (for anyone else who may not find it)

I don't embarass that easily...
But when you go to the pan/crop "F window", if you grab a small square in a corner and drag it all the way down to the smallest it can get, if you keep going, it flips it vertically.
(and I've known how to do that)
So anyway, never did it by right-clicking on the "F" though, so now I know.
Of course, if you really want to mirror, use the Vegas Mirror fX. Start with the "Reflect Left" preset. You get real mirror images. You can put a frame around the mirrored (reflected image) or not.
If you want to see a nifty use of this fX (he said with absolutely no modesty), then download this WMV of something I did three years ago, when I was still actually doing creative stuff. It's high school division 4 volleyball, but three of the girls went on to play at division 1 colleges. Lots of fun to put together the highlights, and I had to create my own media manager to help me sort, preview and access the highlight clips.
