Thanks Gavino.
I was trying to avoid sounding like a total avisynth noob but, gulp here goes..
Code:
LoadPlugin("C:\...DGDecode.dll")
vid=mpeg2source("F:\....d2v")
#As is no doubt obvious I'm not sure of the syntax for this. It needs a vid and more
ScriptClip("""
x = current_frame #variable
a = 2.9017E-08 #constants
b = 2.41882E-03
c = -2.47594795
pdown = a*x^2+b*x+c #number of pixels to crop from the top of the 1080 frame
pd=Round(pdown) #whole number of pixels to crop from the top of the 1080 frame
pup = 360-pd #whole number of pixels to crop from the bottom of the 1080 frame
Crop(320, pd, -320, -pup)
""")
I'm posting this not because I think it's anywhere near right but to try and clarify what I'm trying to do. Any pointers gratefully received.
