A practical jurisdiction hearing for one frame, one displaced duplicate, and every version of the subject insisting it controls Tuesday afternoon.

Ether-MOSH Self Blend compares every RGB pixel with a diagonally offset copy of the same current frame, takes the absolute difference, and mixes that result back over the source. Amount controls the mix; Spread controls the offset. Find it under Color Chaos. Start at Amount 0.34 and Spread 0.012 for readable colored contours without erasing the whole subject.
