Getting started
Motion tracks
One preset is one motion. A track is how you get several in the same clip — a ticker along the bottom while a carousel runs above it, say.
What a track holds
A track is a self-contained mini-clip. It carries its own template, its own control values, its own easing curve, its own slice of the image list, a blend mode, and a window on the timeline. The renderer draws one container per track, in order, so tracks composite over each other the way layers do.
There is still only one clock
Tracks never keep their own time. Each one is handed the length of its window as its total frame count, so it loops seamlessly inside that window rather than against the whole clip. A single track spanning the whole clip behaves exactly like having no tracks at all — that is a property the project holds itself to, not a coincidence.
Where values live
The track is the source of truth for values and easing. Nothing writes those into the scene directly — which matters if you are reading the code: reach for the track, not the scene, when you want to know what a layer is doing.
Reusing a small image set across many cards
Some families place hundreds of cards — a woven gallery wall, a scatter field. Those cycle a small image set across the whole field instead of demanding one file per cell, so six photos can fill a wall.
