Draw the areas to light on your projector and play videos and images inside every shape: up to 8 sources, pixel-exact, live. Lumask is a mask-based projector control app. The canvas is your projector's whole screen, in pixels: draw the areas you want to light and play a video or an image inside every shape. Everything outside the shapes stays black. DRAW ON LIGHT • Rectangle, square, ellipse and free shape with straight segments • Every shape moves, resizes, rotates and has its own edge feather in pixels • Magnet: sides, centres and corners snap to the other shapes and to the edges, with no gaps • Select several shapes, even from different sources: move and resize them together, group them, duplicate them or assign them to another source with a right-click • Undo and redo every change with ⌘Z UP TO 8 SOURCES • Every shape belongs to a source, A to H, with its own video or image • Files are used in their original format: nothing to crop beforehand • Independent position, X and Y scale and rotation for every source • "Linked to the shapes": move, resize or rotate a shape and its content follows LIVE • Fades: cut, 0.5, 1, 2 or 3 seconds • Full-screen output on the projector, one canvas pixel for one output pixel • Test grid to line up projector and surfaces on site • Show keys: B for black, G for the grid, 1–8 for the sources • Saved layouts: recall the masks of every stage with one click INCLUDED • Four 16:9 video loops to try it straight away • English, Italian, Spanish and Portuguese Formats: MP4, MOV, M4V, PNG, JPG, HEIC, TIFF. Requires a projector or external display connected to your Mac. Privacy: Lumask collects no data and never connects to the Internet. Your files stay on your Mac.
