Hi Men, I have a dvd that has a lines in the edge of the bottom and the top and i want to remove them before making a kvcd, so i crop it but when i see the image, it has deformed, and my question:
How can i remove theses lines(noise) without deforming the image???

## Main section and static filters ###
DGDecode_Mpeg2Source("C:\DVD\Tenias.d2v")
Crop (0, 4, 720, 56
#
undot()
asharp(1, 4)
gripCrop(352, 288, overscan=2, source_anamorphic=false,dest_anamorphic=false)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(1.5))
MergeLuma(blur(0.1))

The problem is when cropping an image to a state out of orig mpeg2/1 specs GripFit wont recognis its Pixelaspect Ratio (PAR) anymore and assumes that the input is a PAR1:1 like Divx!

So do bring it to these specs again by adding just black borders

DGDecode_Mpeg2Source("C:\DVD\Tenias.d2v")
Crop (0, 4, 720, 56.Addborders(0,4,0,4)

Or EVEN more comfortable just use the letterbox command as its the SAME like the line above but only ONE command.

DGDecode_Mpeg2Source("C:\DVD\Tenias.d2v")
Letterbox(4,4,0,0)

This overlays just black areas to your noisy edges by keeping the output in 720x576 which will be right handled by GripFit.
