This script tries to intelligently find the best video frame size that would
look good in the desired device (N770 or N800) while trying to keep the same
aspect ratio as the original clip, as well as trying to fit the aspect ratio of
the device.

It will try to change the framerate only to fit the capabilities of the device.
