One may also want to specify the conversion matrix, although the default "Rec601" (for SD, based on vertical resolution) is fine.

(P.S. I just noticed that your uploaded telecined sample (x264 encoded YV12) has been encoded as progressive. It should have been encoded as interlaced, I think.)
Yes, the x264 sample was inherently converted to yv12 by the encoder. Though the "interlaced" parameter seems to only affect the output of yv12. There is no chroma ghosting when I convert to YUV422 or YUV444
Code:
ConvertToYUV422(interlaced=false)
tfm()
TDecimate()
