Jitter in 720p video with frame repeats.

[WattoDaToydarian]

I got a video with frame repeats that has a jitter after I process it with Decimate.
I go from a 720p mpeg2 ts @59.97fps (Finding Nemo sample source 20MB) (http://watto.gotdns.org/FindingNemosample.mpg) then process it with avisynth>virtualdub-mod @ 23.98fps using xvid and ac3 (FindingNemosample 7.86MB) (http://watto.gotdns.org/FindingNemosample.avi)
This is the script I use:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\Decomb.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\NicAudio.dll")
MPEG2Source("FindingNemosample.d2v")
Decimate(2)
video=Decimate()
audio=NicAC3Source("FindingNemosample T01 3_2ch 384Kbps DELAY 0ms.ac3")
AudioDub(video,audio)
Neuron2 has already told me that it has blended fields and hates them (I don't blame him).
Does anyone have a solution to the jittery without removing the Decimate command?

Actually, as it is 720P, it has blended frames.

I won't touch stuff like that with a 10-foot pole. :)

Are you saying that all 720P stuff has blended frames?
I used to use this same script to process 720P movies and it would work fine with no jitter.
This just seemed to start when the frame repeats came along.

This just seemed to start when the frame repeats came along. It's a coincidence. You can disable the rendering of the repeats by setting Ignore Pulldown Flags and you will still see blended frames in the video.
