Problem
A workstation exhausts RAM and begins paging to the same SSD used for media cache, turning memory pressure into storage contention.
Solution
Root Cause / Diagnostic:
When complex timelines (loaded with high-resolution graphics, RAW video clips, and unrendered plugins) exceed physical system RAM, the operating system kernel allocates virtual memory paging files (swapfile). If the pagefile resides on the same SSD volume designated for active NLE media scratch/cache, intense random read/write thrashing saturates SSD IOPS and PCIe bandwidth, causing total system freezing.
Actionable Fix:
1. Dedicated OS & Scratch Drive Segregation: Separate system virtual memory and NLE scratch cache onto dedicated physical NVMe drives (e.g., Drive C for OS/pagefile, Drive D for NLE scratch/cache, Drive E for source footage).
2. RAM Capacity Expansion: Upgrade physical workstation RAM to a minimum of 64GB (for 4K editing) or 128GB+ (for 6K/8K RAW and multi-layer motion graphics workflows).
3. Memory Allocation Cap Configuration: In NLE preferences (e.g., Premiere Pro Memory preferences or DaVinci Resolve System Settings), reserve at least 16GB–20% of system RAM exclusively for the OS and background applications.
Pro Tip:
Never put your Windows pagefile and your video editing cache on the same SSD; when your PC runs out of RAM, your SSD gets hammered from both sides, freezing your editing timeline completely.
