Create frame_updater.lua
- set up a folder with overlay frames - name them like this: `frame_3x2`season`.png` (winter, spring, summer, autumn) - setup your game capture source to have a filter that resizes your source to either 1440x960 (3:2) or 1280x960 (4:3) - set up `pad to frame` filter if you need to have padding - enjoy your frames/overlays auto-switching
