AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave() is necessary?

Hi,
and I'm a ***

please consider this avisynth script:

Import("v:\automazioneclip\avisynth\plugins\IResize.avsi")

LoadPlugin("v:\automazioneclip\avisynth\plugins\LSMASHSource.dll")

LWLibavVideoSource("c:\HD420HQsistemline720_50P.mxf")

ConvertToYUY2(interlaced=false)

LanczosResize(1920,1080)

AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave()

where my source .mxf is 50P

50 frame per seconds

but I need to reduce it in my catrazor timeline so that it matches to a "standard" 25 fps

Because of that is "well" insert the line ---> AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave()


but in this way I get a interlaced output

I wonder: can I modify the script so that I get a 25 fps progressive output non-interlaced?

or

can I replace the the line: AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave()

with another thing that can render progressive ??

SelectEven() or SelectOdd() to go from 50p to 25p

25p will be jerky and flickery if you have high contrast and a lot of motion.
