Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.
Auto Framing is another new feature coming to both 4K and 8K video capture. It uses AI to lock onto subjects and automatically tighten framing to what you want to capture. Even during brief testing, I was intrigued and liked the dramatic punch-in effect as I recorded nearby people. It creates a faux-panning effect as it tracks moving subjects, something you might have experienced with Center Stage on Apple devices.
