dedot

Reduce cross-luminance (dot-crawl) and cross-color (rainbows) from video.

It accepts the following options:

m

Set mode of operation. Can be combination of dotcrawl for cross-luminance reduction and/or rainbows for cross-color reduction.

lt

Set spatial luma threshold. Lower values increases reduction of cross-luminance.

tl

Set tolerance for temporal luma. Higher values increases reduction of cross-luminance.

tc

Set tolerance for chroma temporal variation. Higher values increases reduction of cross-color.

ct

Set temporal chroma threshold. Lower values increases reduction of cross-color.
