Compression Artifacts압축 아티팩트

Recreates JPEG block edges, ringing, and color bleed to give an image a visibly compressed look.

It looks like a normal screen briefly breaks up and recovers. Misaligned color bands and flipped fragments make the signal feel unstable.

`intensity` defaults to 0.5 and ranges from 0 to 1 to set glitch strength and frequency. `speed` defaults to 1 and ranges from 0.1 to 5, while `rgbShift` defaults to 5 and ranges from 0 to 20 to change pattern motion and color separation. `blockDensity` defaults to 10 and ranges from 2 to 50, and `scanlineIntensity` defaults to 0.2 and ranges from 0 to 1 to set band density and scanline visibility.

Place an image or video layer below it. It can pair with `CRTScreen` or `VHS`, but continuous strong distortion competes for attention, so it works best in short moments such as a title or transition.

When to use

Use it for music-video titles, brief transitions, and cyberpunk-inspired posters. Avoid it for long-form text or stable product screens.
