Data Mosh

데이터 모싱

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

Changes apply to the demo above and to the code tabs. Descriptions come from the library registry (MIT).

NameValueDefaultRange / optionsDescription
intensityIntensity0.70 – 1 (step 0.01)How much of the image locks and smears — the fraction of corrupted macroblocks
blockSizeBlock Size4830 – 150 (step 1)Macroblock size — the granularity of the corruption
driftDrift0.350 – 1 (step 0.01)Motion vector strength — how fast corrupted areas drag their pixels away
churnChurn0.40 – 1 (step 0.01)How often each block re-rolls its fate — low values let corrupted regions melt for a long time before recovering
blendBlend10 – 1 (step 0.01)Blend between the live image and the moshed stream
speedSpeed10 – 4 (step 0.1)Simulation speed. 0 freezes the decay in place.
seedSeed00 – 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.
