[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
- [x86]: AviSynth+ or AviSynth 2.5.8 or greater
- Supported color formats: RGB24, RGB32, YV12
- SSE2 capable CPU
[edit] Limitations
- Sampling at 1:1 resolution is known to be unstable.
- This filter is not made for upsampling.
[edit] Syntax and Parameters
- debicubic (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", bool "lsb_inout", float "b", float "c")
- debicubicY (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", bool "lsb_inout", float "b", float "c")
- clip =
- Input clip.
- clip =
- int target_width =
- int target_height =
- presumed 'native' resolution.
- int target_width =
- float src_left = 0
- float src_top = 0
- float src_width =
- float src_height =
- Optional crop rectangle in the input frame.
- float src_left = 0
- bool lsb_inout = false
- 16-bit input and output; uses DitherTools' Stack16 format.
- bool lsb_inout = false
- float b =
- float c =
- The parameters b and c can be used to adjust the properties of the cubic,
- they are sometimes referred to as "blurring" and "ringing" respectively.
- float b =
- debicubicY ignores chroma planes.
