How it works
Canvas
The frame everything happens inside: its shape, what sits behind the cards, and the guides that keep your content out of the places a platform will cover.
Shape
6 presets — 3:4, 4:5, 9:16, 1:1, 4:3, 16:9 — plus an exact pixel size when none of them is the answer. The presets are built from a fixed longest edge, so switching shape reframes the scene rather than rescaling your work.
Some presets set the shape for you when you pick them. That is not the app being opinionated: those motions were authored against a specific frame, and their framing is measured against its half-height — at another ratio the sides show a different amount of the ring, which is a different composition.
Background
Three sources, and the third is the interesting one.
| Source | What it does |
|---|---|
| Colour | A solid, or a two-stop gradient when you turn gradient on. |
| Image | Your own file behind the cards, with a blur so it reads as a backdrop rather than competing with them. |
| Card | The featured card itself, reflected and blurred behind the scene. The background follows the motion — as the featured card changes, so does the wash behind it. |
A background you set explicitly is remembered as yours: the presets that would otherwise impose a white backdrop leave it alone once you have made a choice.
Safe-area guides
An overlay marking the edges a platform is likely to cover — the caption bar, the profile row, the buttons stacked down one side. They are drawn on the stage only: they never appear in the export, and turning them off changes nothing about the file.
Worth switching on before you finish rather than after, because the fix for something sitting under a caption bar is usually a different canvas shape, not a nudge.
Logo slot
A single image pinned to a corner, with a size, kept separate from the card list so it is not swept into the motion. It sits above the scene and stays put while everything else moves — a watermark, a wordmark, an end-card badge.
