You can use
AVISynth (preferably version 2.5.7) in conjunction with
AVSP to help simplify the process of creating a custom video processing script. The resulting .avs file can be opened up in just about any video editing software as an .avi file.
If you want, I can even create a script for your editing purposes. You'll need AVISynth installed on the system that you want to process the video on.
