Windows note: Windows shows a SmartScreen prompt for all independently distributed software. Click "More info", then "Run anyway". This is standard for apps outside the Microsoft Store.
Install in four steps
Download and run the installer for your platform above. It installs the standalone app and the NLE plugins together.
Open Grain & Grit Machine and activate with the licence key from your purchase email. The activation button is in the menu, top right of the editor.
In Premiere or After Effects, drag GGM onto your clips in the timeline.
Pick a stock, dial it in, apply to clip.
