This sample requires inverse telecine correct? top field first?

TFM(order=1)
TDecimate()

Yes, the script is correct. But you don't usually need to specify the field order as most (including your sample) don't need it. In addition, decimation of anime is often helped by using Mode=1. From the TDecimate doc:

Mode 1 = Exactly like mode 0, except instead of decimating the M most similar
frames, frames are decimated from the longest remaining strings of
duplicates. The duplicate detection uses the dupThresh parameter. This
mode is the correct type of decimation for anime and other sources where
frames are repeated 2, 3 or 4 times in a row...

So, I'd do it like this:

TFM()
TDecimate(Mode=1)

But in almost all cases your script will work just fine.
