Datamosh

Datamosh deliberately corrupts video data to create surreal glitch effects. Originally done by hex-editing video file bytes. This browser tool gets you the same look with pixel sorting, frame blending, and block displacement, no technical knowledge needed.

How to use Datamosh

Upload a video (MP4, WebM, or MOV). High-motion footage gets the most dramatic datamosh look.
Choose a glitch mode: I-Frame Drop (classic melting), Pixel Sort (color streaks), or Block Displacement (chunky shifts).
Set intensity. Low values (0.2–0.3) give a subtle effect; higher values produce extreme corruption.
Pick color channel targeting if desired — isolating red or blue gives separation unlike a full-channel sort.
Optionally keyframe intensity to animate the corruption over time, then Export as MP4 at up to 4K.

Tips

I-Frame Drop at low intensity (0.2-0.3) gives a subtle, controlled glitch look.
Pixel Sort on the red or blue channel alone creates more color separation than sorting all channels.
Keyframe intensity from 0 to 1 over a few seconds for a "corruption spreading" effect.
High-motion footage works best. Talking heads and static shots produce less visible results.
