I've installed Camtasia 3 on my MacBook Pro. I'm running a VM from Virtual Box with a resolution of 1280x720. 

When I'm starting the recorder and wan't to do a selection of 1280x720 i get a much smaller (maybe 25%) selection.

I can't figure it out.

Found the solution:

720p is in fact that small on a retina screen.  720p is 1280x720 pixels.  Your retina display is 2880x1800 pixels.  The 1440x900 refers to "points" not pixels.  On a retina screen, a single point is actually 4 pixels.  On a retina display, 4 times as many pixels are used to display the same sized image as on a regular display.  This is why everything looks sharper.  There are more pixels available to create more detail.
The problem is that video sizes are always measured in pixels, not points.  If you record your entire screen, you are going to get a video that is 2880x1800 pixels, and that is how big every video player in the world will think your video is, because that is how many pixels it contains.  If you open up QuickTime Player, and use it to record your screen, and then check the size of the resulting video, it will say 2880x1800.
