Topic: Why does PAL to NTSC give blurry parts of the picture?

Can SVP convert 24fps videos to 48fps without giving picture glitches such as blurring?

If so, I was wondering why converting a 1080i PAL wrestling video from 25 fps to 720p 59.94 fps creates blurring in some parts of a video. Such as in a wide shot of the whole ring where you can see wrestlers running off the ropes. They look blurred. The majority of the video looks perfect, it's just those wide shots that's the issue - they don't look any better than using ConvertFPS(59.94).

This is the script I use:

Yadif(mode=1, order=1)
Spline36Resize(1280,720)
InterFrame(GPU=false, Tuning="Smooth", OverrideAlgo=13, Cores=1)

I ended up with that script as it doesn't give any artifacts. GPU true didn't look any better and caused artifacts to appear.
Default Tuning Smooth Algorithm is 23 for OverrideAlgo but gives more artifacts than 13 and isn't any smoother in the framerate.

It can be blur at the source.
Can you give short video clip or screenshot of blured and non blured wrestlers at the same frame?
