16GB vs 32GB RAM for 4K video editing: 32GB is the actual floor for comfortable work

16GB works only with simple timelines, proxy files, and no heavy effects. The moment you add color grades, stabilization, or multiple 4K streams, you hit the swapfile and your timeline becomes a slideshow. 32GB is where DaVinci Resolve or Premiere Pro stop fighting you — it’s not overkill, it’s the point where exports don’t crash.
