How could I make a map zoom in effect? I'm the only one that knows how to use a computer in the family and so I've been asked to produce a video for a wedding. One of the main requirements for the video is that a map location must be zoomed on. Something similar to this:


                
            

I guessed Google Earth would be the best tool for this, however it wasn't as simple as I first thought as the app takes a while to download map data and sometimes the camera location jumps when zooming in. I tried using the built in video tool within the mac Google Earth app to achieve the effect, but then discovered that you have to pay to export the video. Unfortunately the price is too steep for this one project...

How can I overcome this problem? Or are there any other methods I could try to achieve this effect? Would screen recording Google Earth be the right thing to do (potential copyright issues)? 

Thanks in advance.
There's a good tutorial of how to do this at videocopilot, called earth zoom.  The tutorial uses after effects, but the technique will be the same for whatever software you use.  I'm making this answer a community wiki in case anyone wants to elaborate.
