[HELP] Video stuttering after processing

[Takaji]

Tried a new capture method using VirtualDub2, and used UtVideo YUV422 BT.601 VCM codec to get a lossless capture.

I then tried using QTGMC deinterlace with top field first (this despite Hybrid telling me it was bottom field first on analysis), and the result is a nice and smooth video.
