Bilinear or bicubic resize for VCD?

[joedotcom]

I noticed that AVI2SVCD defaults to bilinear resize (in avisynth setup) for VCD conversion as opposed to bicubic which it automatically selects when coverting to SVCD. Was wondering if I should change it to bicubic for VCD or is bilinear the best setting quality-wise for VCD?

I use, LanczosResize, as do a bunch of people.

I think it only matters when you increase the size,
Fortunately a VCD is so bad that it won't make any difference

Thanks, but the problem is in AVI2VCD you only have the three options (Simple Resize, Bicubic and Bilinear). I always use bicubic for SVCD conversions but don't know if that applies to VCD as well.

I write my own AVISynth scripts, so its not an issue. But yea its a VCD so it wont matter how you resize it, it'll look bad reguardess(IMO)

FOO - I am increasing the size: from 320x240 (NTSC) to 352x288 (PAL). Any thoughts?

No thoughts at all. My head is empty.

Bilinear uses the two nearest pixels and is faster,Bicubic uses 4 nearest and gives you a better picture(less blocks).

You use billinear when you are only resizing one way, horizontal or vertical, ie: 720x480->352x480.

You use bicubic when you are resizing both ways, ie: 720x480->352x240.

Also generally speaking, you want to use bicubic anytime you are increasing resolution.

As a byproduct of how bicubic works, you get sharper picture which is actually a bad thing with such low bitrates as VCD, but since your source seems to be pretty low quality to begin with, I assume its already very compressible.

I would use bicubic simply because you are increasing resolution.
