A set of Vapoursynth plugins and script based on the 2007 paper "Reduction of Dot Crawl and Rainbow Artifacts in the NTSC Video" by Ji Won Lee et al., which outlines a technique for temporal and spatial filtering of these artifacts.

Motion estimation and compensation make use of vapoursynth-mvtools.

Compile dotdetect, rainbowdetect and dotblur separately, and process a clip with script.vpy to try it out.

This method introduces significant blocking and undesirable blending artifacts and is not recommended for regular use.

You can’t perform that action at this time.
