Hi all!
May be will be useful make upsizing before IVTC for accurate field matching

source=AVISource("cap.avi")#720x576 YUY2
sourceu=source.LanczosResize(1440,576)
sourceu=sourceu.tfm()# or Telecide(guide=0)
sourceu.Spline36Resize(720,576)

Source pal 2:2 telecined.
yup.

:Edit: Sorry, had my brain inserted at right angles. Just ignore what I said.

@Yup, Think about it a bit more.

IanB!
That is means?
Please explain.
source=AVISource("cap.avi")#720x576 YUY2
sourceu=source.LanczosResize(2880,576)
sourceu=sourceu.tfm()# or Telecide(guide=0)
sourceu.Spline36Resize(720,576)
For this code I see small improvement, may be due te filtering.
yup.

why should an increase in pixel count improve matching?
just raise tfms detections parameters instead!

May be mode=4,PP=0,slow=2 or others?

just read the doc and try.

but upsampling the video for sure is not a good idea...
