[edit] Description

This filter is designed to reverse the effects of bicubic upsampling. Parameters and sampling pattern try to mimic Avisynth's BicubicResize.

Note: Descale is recommended as a modern replacement for Debicubic.

[edit] Requirements


[edit] Limitations

  • Sampling at 1:1 resolution is known to be unstable.
  • This filter is not made for upsampling.
