Hi-
It's field-blended from an NTSC source. You'll have to unblend it and return it to film speed. One such script might go:
LoadPlugin("C:\Path\To\DGDecode.dll")
LoadPlugin("C:\Path\To\MT_MaskTools.dll")
LoadCPlugin("C:\Path\To\Yadif.dll")
LoadPlugin("C:\Path\To\TIVTC.dll")
LoadPlugin("C:\Path\To\Average.dll")
LoadPlugin("C:\Path\To\RemoveGrain.dll")
MPEG2Source("C:\Path\To\Test.d2v")
Import("C:\Path\To\SRestore.avs")
Yadif(Mode=1,Order=1)#or your favorite bobber
SRestore(FRate=24)
Adjust the script for your names and paths. Get and read up on SRestore here (it's part of the R_Pack you'll download):
