Problem with resize ratio. Please help

[chiyoaiki]

I have been converting avi to dvd using CCE. I create AVISynth Scripts following Games-Realm's 'How to Convert AVI to DVD + AC3 with CCE and AC3Machine' guide. However the output is not full screen (there are black horizonal lines on top and bottom).

My avi file is 512x384.
AVISynth Script:
avisource("C:\filename.avi")
LanczosResize(720,540)
AddBorders(0,18,0,18)
ConvertToYUY2()
ResampleAudio(44100)

What calculation did I do wrong?

Thank you.

Forgot to mention that I did the calculation for 4:3 movie.

It's doing what you told it to do.

LanczosResize(720,540)

makes it 720x540 (which is 4:3 aspect ratio for an AVI source) and

AddBorders(0,18,0,1 )

makes it 720x576, which is a the correct PAL resolution.

So you added black borders to it to get the DAR(4:3) right for the difference between a 1:1 computer source and a TV. That's how it's supposed to look. If you want 'full screen' your going to have to cut some sides off before re-sizing. Quite a bit going to PAL as opposed to NTSC.

I have tried with

BicubicResize(720,576)
AddBorders(0,0,0,0)

but I got black screen throughout the movie.

So what is the correct way to calculate? Please explain.

Also what is the different between LanczosResize and 'BicubicResize?

Thank you.

PS Sorry there was a mis-typed in my first post. I originally used

AddBorders( 0,18,0,18 )
