5 Things to Know About 32GB RAM and 4K Timeline Scrubbing

32GB RAM helps keep timeline scrubbing smooth in 4K It gives the system enough breathing room to keep more preview frames cached, so jumping around a timeline with 4K ProRes or h.264 footage works better than with 16GB.

RAM alone won’t fix a slow storage drive If your source footage lives on a spinning hard drive, scrubbing will stutter regardless of how much RAM you have. An SSD is essential.

A weak GPU is often the real bottleneck The video card matters more than RAM for real-time playback. Upgrading to 32GB is pointless if your GPU can’t keep up.

Proxies make even 16GB sufficient for 4K editing If you use proxy files (which you should), the RAM requirement drops significantly. 32GB is overkill for proxy workflows.

32GB is a solid upgrade if you run multiple apps It helps when you have many browser tabs or other programs open alongside your editor. But ensure your SSD and GPU can match the RAM upgrade.
