HorizontalReduceBy2() vs other Resizers?

[Piper]

I'm wondering what the general opinion is for optimal resizing of a 704x480 (captured & cropped 720x480) Huffyuv source to Half D1 (352x480)? What I'm after is a method which yields the sharpest results without introducing ringing. I'd also like to avoid using sharpen filters.

My current script looks something like (from memory).

AVISource("d:\capture.avi")

KernelDeint(order=1,threshold=4,sharp="true")
Convolution3D(preset="movieHQ")
GuavaComb(Mode="NTSC",Recall = 75,MaxVariation=25,Activation=30)
Crop(8,0,-8,0)
HorizontalReduceBy2()


I've looked for comparisons of the HorizontalReduceBy2() and other common resizers but I haven't found anything tangible.

Any thoughts on this script, resizing etc?

Reduce is very similar to BilinearResize. There has been written a lot on different resizers. But in general the sharper a resizer you use the more aliasing you will get, but I prefer a sharp resizer (lanczos) to a sharpening filter. But if you are doing VCD you might stick to bicubic, since lanczos is hard to compress.

Thanks sh0dan. That is what I was looking for.

I'll most likely stick with Lanczos for DVD encodes and Reduce or Bilinear for DivX (against same source).
