Layer mix

Choose a base image (sets output size) and overlay images. Each overlay gets its own random position (scatter avoids stacking in one spot; grid uses separate cells with random jitter). On the timeline, overlays appear one after another; earlier overlays stay on the base at their positions while the next is added. Optional MP4/WebM is for “video under base” when enabled. Play live preview or scrub the output timeline. Export WebM or MP4.

How it works

Use the controls on the right to load a base + overlays. Then open Tweak in the header to preview, scrub, and export.

Icon guide

Menu: site pages + theme.
Tweak: opens preview + scrub + export.
PiP: floats the preview in a draggable “Tweak” window.
Random: new random positions for each overlay (cumulative).
Export: WebM in-browser or MP4 via server transcode.

Load a base image and overlays to begin. Open Tweak for preview.
