  1. 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.

    I think the field order is wrong: encoded as TFF, flagged as BFF (or the reverse).

    Cheers,
    David.

  3. It's interlaced though isn't it? I thought it it's interlaced then you should use TFF which I did?

    Is there any way to find out if the source is TFF or BFF?

  4. Sure, use mediainfo -- but wouldn't it be just as quick to reencode a few seconds with the parameter switched and see how it looks?

    That's what you'll end up doing anyway.

    And no, not all interlace is TFF, DV for example.

  5. "AssumeTFF()" is probably wrong for that particular video.

    Been through this a few times earlier. Load this script and observe frames with motion in VirtualDub, one frame at a time:

    AssumeTFF().SeparateFields()

    If you see smooth motion, the field order is TFF. If motion is back and forth from field to field, then it's BFF().

  7. Thanks I tried BFF and it's working now.

    Methinks that whoever did this earlier deinterlace/reinterlace/encode screwed up a bit and gave you some jaggies on angular lines that you don't want. A fairly clean vid for a change, all I used was MCTemporalDenosie, Deblock_QED, and some light TemporalSoften. But your black levels, contrast and gamma are way off:

    Adding red was good, but you also need some blue. Everybody's orange without it.
