In Quicktime Player X, when you want to start a screen recording, you can either record the whole screen or drag to select a region. In the latter case, if you want a specific size (e.g., 1280x720), the best you can do is guess as you are dragging the mouse.
Can I use AppleScript to tell Quicktime Player to select a specific region size? I'll be happy to drag it into its final location manually, but if I could at least automate the part of initially specifying the region size, I'd be happy.
Is this possible? Where do I start looking for documentation?
