Built-in flashes

Common parameters

Most flashes open a param modal with:

Preview panel

Hover any flash button to preview the effect in the always-visible preview panel on the right. Mouse-leave resets to placeholder.

User Flashes

Save your own custom flash by building it on a solid layer, then capturing it as a preset. Saved flashes preserve the solid color and every effect on the source layer, so you can rebuild complex looks reliably.

Saved flashes live in {USER_DATA}/MotionLab/saved-flashes.json.

Reversed layers
Flashes anchor to the visible start of the selected layer regardless of stretch direction — a flash applied to a reversed clip still lands at the beginning of the clip on the timeline.
