How to Deinterlace and improve picture quality ( cleanup & sharpen)

[Akuma786]

Hi, I have this vhs to DVD transferred movie. Can anyone suggest how to deinterlace it properly & improve picture quality ( clean up, sharpen ) using avisynth please. Maybe upscale to 720p, if picture not effected so much.

Script so far, is this the correct way:

a = LWlibavAudioSource("G:\STAL PROJECT FILES\Demux files\VTS_01_1 T80 2_0ch 192Kbps DELAY 0ms.ac3") # get audio (decompressed to PCM)
v = Mpeg2Source("G:\STAL PROJECT FILES\Demux files\VTS_01_1.d2v", Info=3) # get video
AudioDub(v,a) # join audio and video together
AssumeFPS(24.0, sync_audio=true)
Crop(0, 130, -4, -126, align=false)
AssumeTFF()
ColorMatrix(mode="rec.601->rec.709")
import("C:\Users\akuma\AviSynth+\plugins64+\RemoveDirtMC.avs")

QTGMC(preset="Fast", FPSDivisor=2)


RemoveDirtMC(15, false)

SMDegrain(tr=3, thSAD=400, RefineMotion=false, contrasharp=false, interlaced=false, plane=4, prefilter=0, chroma=true, lsb=false, lsb_in=false, lsb_out=false, Show=false)

nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1280, fheight=588)
aWarpSharp2(depth=3)
Sharpen(0.30)

AssumeFPS(24000, 1000, sync_audio=true) # audio sample rate reduced from 48000 to 46080 (lossless)
SSRC(48000) # convert audio to 48000 Hz samples

Prefetch(12)

As far as I can see, deinterlacing is not required because it's PSF (progressive segmented frame). If you Deinterlace to double rate, you'll see that both fields for each frame are the same. And of course there are no jaggies, despite lots of motion.

Oh okay, so no need to deinterlace then. Thanks

What can I do to improve picture and is there any filter which can stop the rare jumpy frames ?

Some of the jitter is pretty bad. There are a couple of scripts may alleviate some of it:
Stab() and Depansafe()

mpeg2source("C:\Users\davex\Desktop\avs_test\depan.d2v")
qtgmc(inputtype=2,preset="medium")
crop(0,124,-0,-122)
depansafe(dxmax=4,dymax=4)
crop(2,6,-4,-8)

Thank you davexnet. I'll try this.
