Topic: Input Resize, Bicubic or Spline?

When resizing the input, it uses the Bicubic algorithm. Doesn't spline give a better output without costing much more on performance?

Ideally the best would be the equivalent of madVR's Spline 4-taps with Anti-Ringing filter, but I might have to search a little bit online if Anti-Ringing is supported with AviSynth Spline.

Bicubic was selected as one of low cost (not very slow) and good looking downsize picture scaling algorithm.

Re: Input Resize, Bicubic or Spline?

It should be mentioned that, when it comes to downsizing, even the highest quality of algorithms will not look noticably different from your typical lanczos or bicubic.

It is in upscaling where the difference in quality can be notable.
