Checkmate

Spatial and temporal dot crawl reducer. Checkmate is most effective in static or low motion scenes.

Ported from AviSynth plugin

Usage

vszip.Checkmate(vnode clip[, int thr=12, int tmax=12, int tthr2=0])

• clip
  clip to process. Any format, 8 bit only.

• thr
  spatial threshold. Controls the spatial filter, higher values will blend more but cause artifacts if set too high. If set too low, lines in static scenes where dot crawl was reduced will become slightly more blurry. 12 by default.

• tmax
  controls the maximum amount by which a pixel's value may change. Higher values will increase the strength of the filtering but cause artifacts if set too high. 12 by default, any values between zero and 255 allowed.

• tthr2
  temporal threshold. Controls the temporal blending; higher values will blend more but cause artifacts if set too high. Setting this to 0 disables the temporal blending entirely. This may be helpful to reduce temporal artifacts in high motion scenes. 0 by default, must be non-negative.
