IVTC: Issue with TFM as oppesed to Telecide

[6ari8]

Hello,

I'm trying to edit an Anime DVD I have.
DGIndex analysis says that it's 81.36% VIDEO and while I was indexing the VOB, the Video Type keeps switching from Interlaced to progressive. As I understand, it seems to be a hyprid of FILM and pure interlaced. MeGUI source detection says that the source is hybrid: Mostly film.

I tried to ivtc and deinterlace this with TIVTC with this:

TFM(slow=2, pp=5, clip2=TDeint(mode=2, type=3))
TDecimate(Mode=1, hybrid=1)

But, I get an issue of a jumpy/jerky at the beginning of a pan in some sections where the source is still for a couple of seconds then goes through a vertical pan.

I tried that with Decomb with this:

Telecide(guide=1)
Decimate(mode=3,threshold=2.0)

And the issue is not there and I find the pans are very smooth. However, I perceive a bit of quality degradation as opposed to the first method.

I tried switching the Decimation filter in each of the two methods but I notice no change from the initial observation so I concluded that TFM is somehow causing this jerky pan.

Am I doing something wrong with the parameters of TFM? Why do I get a smooth result with Telecide but can't in TFM?

Thank you.

Try to find the sections that are different, and treat them separately?

Am I doing something wrong with the parameters of TFM?
Who knows? Please provide a sample, one that might show the problem you're having. 10 seconds with steady motion direct from the DVD will be plenty.
