need help with deinterlacing

hello,
i have a BD (concert) which I copied to my HD with makeMKV.
Now I'd like to deinterlace it using for example avisynth.

The BD box cover says the video is 23.98 fps and the frame pattern is 4+2 (4 progressive followed by 2 interlaced).
What kind of command should I use to get it deinterlaced?

Thanks (if needed I will attach small sample)

edit:
ops, I think there is nothing to deinterlace and what I need is some kind of pull-down removal
