Problem
A creator keeps a downloaded platform copy as the new master, so repeated repurposing gradually reduces detail even though each individual export looks acceptable.
Solution
Root Cause / Diagnostic:
Replacing original archive footage with downloaded social proxy files creates progressive generational degradation over subsequent editorial cycles. Each social platform's ingest pipeline applies chromatic sub-sampling (4:2:0), temporal compression, and high-frequency filtering. Successive passes compound color banding, edge halos, and shadow posterization, ruining visual fidelity over time.
Actionable Fix:
1. Implement a non-destructive production storage protocol where raw camera media and initial NLE master exports (.mov/.mp4 mezzanine) are permanently tagged and write-protected.
2. Establish a clear naming taxonomy appending `_MASTER_MEZZ` to original renders and `_PLATFORM_PROXY` to downloaded social assets.
3. Verify file metadata and codec integrity (confirming source bitrate >25 Mbps and 4:2:2 or high-bitrate 4:2:0 profile) before importing archival clips into new timelines.
Pro Tip:
Store a 1080p ProRes 422 or Avid DNxHR master of every completed project on cold storage; storage is cheap, but repairing compounded compression damage from degraded proxy masters is impossible.
