Key ideas

A little vocabulary makes everything else in the app easier to follow.

Projects

A project is everything you’ve built: all your grids, masks, warp paint and settings. You save and reopen projects by name.

Grids

A grid is one layer of projected art. Each grid shows one video, image or shader, and has its own:

• four-corner alignment
• position, size and rotation
• color settings
• background key
• audio level
• playback speed and position

Grids stack on top of each other. You can add as many as you need, reorder them, duplicate them and remove them. Changing one grid never changes another.

Note

You can swap the art on a grid without losing its alignment, masks or color settings. Use CHANGE ART.

What is per grid, and what is shared

Feature	Applies to
Corner pins, position, size, rotation	One grid at a time
Color, Background Key, Audio, Speed	One grid, or all grids with Modify All Grids
Shader settings	One grid
Warp Paint	Shared by every grid in the project
Masks	Belong to the project; each mask is switched on for the grids you choose

Three kinds of “grid buttons”

You’ll see rows of numbered grid buttons in a few places. They do different things:

1. Step 1 (Align): the active grid you are aligning.
2. Tool panels (Color, Background Key, Audio…): which grid the tool edits, or all grids with Modify All Grids on.
3. Mask tool, “MASK GRID”: which grids the selected mask applies to. This is not the active grid.

The two steps

Step 1: Align  →  Step 2: Refine

Step 1 is choosing your art and fitting it to the surface. Step 2 is everything else: masks, warp, color, playback and saving. You can go back to Step 1 from Step 2 with GRID SETUP. See the Quickstart and the warning there about unsaved changes.
