So a final script from me before I move onto other newer concepts. This script is optimised for i7s at any of the two HD resolutions for the maximum smoothness. Artifact suppression is a secondary objective but the script still does very well in terms of quality. Smoothness particularly in 1080p is improved.

Edit: Remember to change num= to whatever you want your output framerate to be
