Locks parts of the image into blocks that drag into pixel trails, like video whose keyframes have failed.

Range / options
Description
intensityIntensity
0.7
0 – 1 (step 0.01)
How much of the image locks and smears — the fraction of corrupted macroblocks
blockSizeBlock Size
48
30 – 150 (step 1)
Macroblock size — the granularity of the corruption
driftDrift
0.35
0 – 1 (step 0.01)
Motion vector strength — how fast corrupted areas drag their pixels away
churnChurn
0.4
0 – 1 (step 0.01)
How often each block re-rolls its fate — low values let corrupted regions melt for a long time before recovering
blendBlend
1
0 – 1 (step 0.01)
Blend between the live image and the moshed stream
speedSpeed
1
0 – 4 (step 0.1)
Simulation speed. 0 freezes the decay in place.
seedSeed
0
0 – 100 (step 1)
Random seed for the corruption layout
Every component also takes blendMode · opacity · visible · maskSource/maskType · boundingBox · id
It feels as though parts of a video frame stay in place and get dragged by the next movement. Like wet paint pulled across the screen, blocks and colors stretch into trails.
`intensity` defaults to 0.7 and ranges from 0 to 1 to change how much of the frame is corrupted. `blockSize` defaults to 48 and ranges from 30 to 150, while `drift` defaults to 0.35 and ranges from 0 to 1 to set block size and how far pixels are dragged. `churn` defaults to 0.4 and ranges from 0 to 1 to set how often blocks change, and `speed` defaults to 1 and ranges from 0 to 4 to control simulation speed.
It needs an image or video beneath it to leave visible trails. Pair it with `VHS` or `Glitch` for damaged-broadcast styling, but keep the motion restrained when small text, logos, or precise outlines matter.
When to use
Use it for a brief, strong impression in music videos, transitions, or animated cover art. Avoid it where captions or logos need to remain readable for long.
