Roto & paint
Shapes with real feather, strokes that stay where you drew them, and an eraser that erases paint rather than plate.
Roto
Roto holds shapes: bezier points with per-point feather, a blend mode per shape, and animation on every control. The rasterizer is coverage-based, so a soft shape has a soft edge rather than a stepped one.
- Draw with the roto tool in the viewer; click to place points, drag to shape tangents.
- Set feather per point where the edge needs it, not globally.
- Key the shape's transform rather than every point when the whole thing moves — it is fewer keys and it survives a re-time.
Paint
Paint stores strokes, not pixels: each stroke keeps its own size, softness, opacity and mode forever, so an old stroke can be re-judged at any time. Four modes:
| Mode | What it lays down |
|---|---|
paint | The brush colour |
clone | The input sampled from a parked source (<kbd>Ctrl</kbd>+click to park) |
erase | The input again — it takes back the paint above it and leaves the plate |
reveal | A second input wired into reveal — a cleanplate, an earlier version |
