Problem
A creator deletes render intermediates without determining whether they are actually unique source composites required for later finishing.
Solution
Root Cause / Diagnostic:
Editors frequently purge cache and render directories to reclaim storage space without distinguishing between disposable preview files and unique intermediate renders. If complex multi-layer composites (e.g., dynamic link comps, screen replacements, or noise-reduced plates) were rendered in-place without preserving source project links, deleting cache destroys the only high-quality composite.
Actionable Fix:
1. Explicit Pre-Render Export Workflow: Enforce a workflow where all complex visual effects or noise reduction plates are formally rendered to dedicated media files (Apple ProRes 4444) stored in an `/ASSETS/VFX_COMPOSITES/` directory.
2. Cache vs. Asset Segregation: Configure NLE scratch disks to keep disposable timeline render caches separate from project media and rendered intermediate assets.
3. Offline Asset Audit: Prior to deleting scratch and cache folders, run an offline media audit in the NLE to confirm that zero timeline clips point to temporary render cache paths.
Pro Tip:
Never put unique visual effects renders in your temporary cache folder; render your VFX shots as ProRes 4444 files into a permanent project assets folder so deleting cache doesn't destroy your hard work.
