need help!

[Ingram]

I have recorded a tv show via SD tv. I have converted it to MPG and all that. I am currently trying to encode it with CCE and dvd2svcd, however I need to crop the image by 2 pixels all around the image, and because the file is interlaced (and I wish to keep it that way) I end up getting these flickering bars when I play it back in powerdvd with deinterlacing on.

I am using the Crop(x,x,x,x) command in the avisynth tab. I need help to know how to do this properly!. Video is pal 25fps interlaced.

thankyou.

Ok firstly, vertical resizing of interlaced footage does not work well. There are ways and means but best avoided if possible.

I suspect what you're doing is

Crop(2,2,2,2)
WhateverResize(720,576).

If the height of the source file is 576 the best way would be
Crop(2,2,2,2)
AddBorders(2,2,2,2)
WhateverResize(720,576)

and just replace the cropped stuff with black, thus avoiding the need for vertical resize.

If either the input resolution is not 576 pixels high, or the AddBorders approach is not acceptable for some reason, try a search on Interlaced resizing.

One other thing though: Are you definitely encoding it as interlaced.
In the deinterlace box (Conversion tab) there are two slightly confusing dettings.
"No Deinterlacing" will encode as PROGRESSIVE but not apply any deinterlace filters.
"Keep Interlaced" will encode as interlaced.
Use this latter one for your encode.

I believe it is already enough clear, but to be precise...

Crop(2,2,-2,-2)
AddBorders(2,2,2,2)
WhateverResize(720,576)

My mistake (again)
