5 Things to Know About RAM for 4K Video Editing

Proxies do the heavy lifting Proxies convert 4K footage into easier-to-play files, so your CPU and GPU don’t struggle with decoding. This means RAM matters less for basic playback.

16GB is usually enough for proxy workflows RAM still handles cache, undo history, and background apps like a browser. But 16GB works fine for most short projects in DaVinci Resolve.

32GB helps with effects and long timelines If you use heavy effects, multiple video layers, or keep many Chrome tabs open, 32GB reduces slowdowns. Long timelines (30+ minutes with many cuts) also benefit from more RAM for caching.

Prioritize a faster GPU or more storage first A better GPU speeds up render times and timeline responsiveness more than extra RAM. Upgrade storage before RAM for bigger real-world gains.

Only buy 32GB if you push the system hard Heavy color grading, Fusion comps, or future-proofing justify 32GB. For typical proxy-based editing, you won’t see a night-and-day difference.
