Datamosh
Last updated
Datamosh is a Distortion effect.
What it does
Section titled “What it does”Imitates what a compressed video does when reference frames go missing.
The blurring/melting follows motion in the footage. Moving objects will smear and static objects don’t change at all.

What each control does
Section titled “What each control does”- Intensity is how much of the prediction is laid over the current frame.
- Displacement is the number of frames used to warp across.
- Bloom affects the falloff of older frames being used in the datamosh.
- Reset interval is how often the melt restarts clean, imitating reference frames.
- Mix: how much of the result replaces the original.
- Matte and Invert drive the strength of the effect from another layer’s brightness; see Effects.
