Is this script already as optimized as can be?

[shoopdabloop]

Or can it be optimized more with no visible difference?

Here's a 7z containing an unprocessed sample, a processed clip of the sample, and the script:
http://www.megaupload.com/?d=4OTM5OL0

the unprocessed sample isn't technically unprocessed; i loaded an AVS with a simple AviSource of the source and a KillAudio into VDM, took a sample of it, and re-encoded it with a dvsd codec (cedocida) very similar to the original (sony dv) because i wasn't sure how to get a sample otherwise. but the post-script output looks identical when operating on the original source compared to the provided sample. (the provided one is compressed with xvid, however)

and just in case you just want to look at the script, here it is:

#MT, removegrain, nnedi2, motionprotectedfps, mvtools2, fft3dfilter, gradfun2dbmod, warpsharp (2003), and depan
