You enable resizing (Crop/Resize->Base->Resize, set the base setting you want).
Then you overwrite the general resizer by enabling "Filtering->Avisynth->Resizer->Resizer".
Select the resizer (i.e. 'BicubicResize') and the resizer specific values (i.e. bluring and ringing) you want.

Which filter is hybrid's default？vapoursynth or avisynth？

[Selur]

By default Hybrid uses Vapoursynth. (whether to use Vapoursynth or Avisynth is controlled by Filtering->Support)

How to set (b= -0.5, c=0.25) in Vapoursynth?Avisyth isn't available in Windows 10.
Thanks

afaik: You can't.
The filters in Vapoursynth are not identical to Avisynth and thus do not have the same parameters.

How Vapoursynth deal with bicubic resize？use (b=0, c=0.75) as default？and how to exam a output video is bicubic use (b=0, c=0.75) or (b=-0.5, c=0.25)?

Just noticed that I missed half of the previous post since you set the font size to 1.
-> is your system broken in some way or why would you do that?

Avisyth isn't available in Windows 10.
Thanks

Avisynth is available on Windows only. So if you can't use it on Windows 10 you are doing something wrong.

and how to exam a output video is bicubic use (b=0, c=0.75) or (b=-0.5, c=0.25)?

Since we are talking Avisynth here: You look at the Avisynth Preview once with settings set to A and one with settings set to B.
If you can't tell the difference between your settings, it doesn't matter for you which settings you use.

It is, you just need to switch Support to Avisynth,... (Lower right corner)
