Flipbook

Rows and cells

A flipbook is a frame whose tracks are rows and whose clips are cells — each cell holds one drawing. Add as many rows as you need. Each cell is drawn using the same brush and vector tools covered in Drawing & brush.

Onion skinning shows adjacent frames faintly while you draw the current one, so motion stays consistent from cell to cell.

Placing, swapping & reordering

Drag a cell onto an empty slot and it moves there. Drag it directly onto another cell and the two swap places. If a drag would land ambiguously across two cells at once, it’s refused rather than guessing.

Reordering is a distinct gesture from placing — drag-to-sort by sequence position, on a single cell or a multi-cell selection at once. The row repacks with no gaps in the new order.

Duplicating a cell makes a real copy with its own fresh drawing surface, never a shared reference. Duplicates remember which cells they came from, so you can select matching layers across all duplicates even after the fact. Copy, cut, and paste cells — including across different rows — preserve whatever internal gaps the selection had.

Gaps, holds & cleanup

Deleting a cell leaves an empty slot — nothing ripples to close the gap automatically. Gaps are first-class, not errors: insert a new cell into a specific empty slot whenever you’re ready.

Drag a cell’s edge to resize its hold— how many frames it’s shown for. Only the cells actually touching that edge move; gaps elsewhere in the row are left untouched. A cell’s start can also be trimmed independently.

When you’re ready to clean up, repack an entire row to close every gap, or close gaps only between the cells currently selected, leaving the rest of the row exactly as it was.

A flipbook frame behaves like any other clip on the timeline — trim it, loop it, or nest it inside a larger composition.
