Original MPEG2 sample

H264 Sample after re-encoding with the below script

Code:

setmtmode(5,9)
Mpeg2Source("E:\Video.d2v", CPU=6)
setmtmode(2)

McTemporalDenoise(settings="medium", interlaced=true) # Sharpening strength is 150

AssumeTFF() # or AssumeBFF() depending on the source
QTGMC(Preset="Super Fast") # Removes interlacing artefacts. Strangely this is faster than Ultra Fast
Vinverse() RemoveSpots() AddGrainC(var=1.0,uvar=1.0) SeparateFields() SelectEvery(4,0,3) Weave()

Tweak(Bright=0, Sat=1.0, Cont=1.0, Hue=10.0, Coring=False)

Crop(8,0,-12,-8)
AddBorders(10,4,10,4, $000000)

I've used this script hundreds of times without problems so I don't understand what's causing the judder. You can see the judder in Windows Media Player or on your TV.
