DivX Pro 5.0 and resizing types

[JimmyBarnes]

Doom9's Guide to DivX5 ripping recommends to use neutral bicubic as the resizing type. I'm wondering how the resizing types in VDub, and GKnot/DVd2AVI equate:

VDub v1.4.10 has bilinear, bicubic, precise bilinear, precise bicubic (A=-0.75, -0.60, -1.00)

GKnot/DVD2AVI has bilinear, soft bicubic, neutral bicubic, sharp bicubic.

In particular, does GKnot/DVD2AVI's bilinear equate to VDub's bilinear or to precise bilinear?

thanx

In terms of compressibility not even bilinearresize() in avisynth compares to precise bilinear resize in VDub.
I tested it with DV homevideo, precise bilinear was substantially smaller at 100% quality encoding while it still preserves the sharpness quite well - I don't like the avisynth bilinearresize(), because it loses too much sharpness and it compresses not as good as precise bilinear.

I like the looks of the soft bicubic resize, though - there is no real equivalent to this in VDub. So, if a source video needs some little noise filtering, I decide from case to case which of those two filters looks better, precise bilinear or bicubicresize(xxx,xxx,b=0.333,c=0.333)

What bugs me is that VDub, AVIsynth and now the DivX Pro 5 codec itself all have versions of bilinear or bicubic resize. I wish there were some standardisation, though I realise this situation potentially offers more choice.

Anyway thanx for all the comments
