Does 32GB of RAM help with timeline scrubbing in 4K video editing?

Yes, 32GB RAM helps with timeline scrubbing in 4K by giving the system enough breathing room to keep more frames ready, while 16GB will choke on 4K ProRes or h.264 footage. But RAM alone won’t fix a slow storage drive or a weak GPU—if your source footage lives on a spinning hard drive, scrubbing will stutter regardless. 32GB is a solid upgrade from 16GB for 4K editing, especially if you run multiple apps, but make sure your SSD and GPU can keep up.
