Hi freinds,

Im trying to encode a DVD of some old Classics into x264 MKV using MEGUI. I'm making anamorphic overcrop 16:9 method. everything is fine but the only problem remains is that i'm not getting rid of the interlacing lines completely.
Here is the Script

DGDecode_mpeg2source("C:\Documents and Settings\Administrator\Desktop\try\111.d2v",info=3)
ColorMatrix(hints=true)
edeintted = SeparateFields().SelectEven().EEDI2(field=-1)
tdeintted = TDeint(edeint=edeintted)
tfm(clip2=tdeintted).tdecimate(hybrid=3)
crop( 0, 68, -2, -72)

Lanczos4Resize(640,352) # Lanczo4 (Sharp)
Undot() # Minimal Noise


The source is 100% film 4:3 704x480 NTSC 23.976024 fps as reported by d2V & i used forced film method for the frame serve.

The int. lines are surely reduced but not eliminated completely. I'm not handy with Avisynth advanced usage so can someone please point me where to get the info to properly deinterlace.

I tried using DGBOB but it blurrs the image badly.
Any example script as a pointer will be of much help since im not much familiar with scripting & functions.
Thx

I wouldn't use the force film flag. Have DGindex honor pull down flags and then analyze again with MeGUI. see if that fixes it.

I used that method also but din't do the trick. Anyways a mate pointed out to use BOB() & just adding that line to the AVS completely removed the interlace line.

Though the picture quality is almost near to superb, I'd still really like to compensate the slight blurriness caused by bob. can u suggest me if there are any good parameters to it ?? or any other good sharpening filter that shall fill up the sharpness?

Thx
