I'm doing captures of Fawlty Towers with a PVR-250 as NTSC 720x480. The quality is marginal and it is interlaced. Can the following AVS be enhanced? I am creating interlaced half DVD at CQ80 through TMPGEnc.

LoadPlugin("C:\video\Filters\kerneldeint.dll")
LoadPlugin("C:\video\Filters\RemoveGrain.dll")
LoadPlugin("C:\video\Filters\STMedianFilter.dll")
LoadPlugin("C:\video\Filters\Cnr2.dll")

Mpeg2Source("H:\ft\ft.d2v",idct=7)
bob(0,0.5)
RemoveGrain(mode=2)
Cnr2()
STMedianFilter(3, 3, 1, 1 )
assumebff()
separatefields().selectevery(4,1,2).weave()
KernelBob(order=1,sharp=true,threshold=7)
AssumeFrameBased()
LanczosResize(352,480,8,0,704,480)
AssumeBFF()
ConvertToRGB24() # For TMPGEnc or VFAPI
SeparateFields()
SelectEvery(4,1,2) # SelectEvery(4,0,3) for bottom field first video
Weave()
LetterBox(16, 16, 16, 16)

Why are you using bob and kernelbob?

I'm using something like this for my Hi8 captures:

Code:
AVISource("D:\capture.avi") 
LeakKernelBob(order=1,sharp=true,threshold=7)
LanczosResize(352,480,8,0,704,480)  
Undot() 
RemoveGrain() 
Cnr2() 
ConvertToYV12() 
Deen() 
Letterbox(16,16,16,16) 
AssumeBFF() 
SeparateFields() 
SelectEvery(4,1,2) 
Weave()

You should put your ConvertoToYV12() just after the Bob as all filters you use work in YV12 and this is 15% faster (or even more).

Thanks for the tip.

I'll use that next time, the script is very slow as it is, I just thought it was due to the field separating...

RemoveGrain is quite slow in YUY2 so you should get a good speedup.

This seems to work well for interlaced captures. I modified for PVR-250 capture:

Mpeg2Source("H:\ft\ft.d2v",idct=7)
LeakKernelBob(order=1,sharp=true,threshold=7)
LanczosResize(352,480,8,0,704,480)
Undot()
RemoveGrain()
Cnr2()
#ConvertToYV12()
Deen()
Letterbox(16,16,16,16)
AssumeBFF()
SeparateFields()
SelectEvery(4,1,2)
Weave()

For NON-interlaced captures, is this the equivalent (like with 24)?:

Mpeg2Source("H:\dog\dog.d2v",idct=7)

Telecide(order=1, guide=1, gthresh=10, post=2, vthresh=50, dthresh=7, blend=false, show=false)
Decimate(cycle=5, mode=0, threshold=0, threshold2=3, quality=2, show=false)
undot()
LanczosResize(352,480,8,0,704,480)
RemoveGrain()
Cnr2()
Deen()
Letterbox(16,16,16,16)
