After testing 20+ parameter combinations, the following produced the highest VMAF (Video Multimethod Assessment Fusion) scores for She Rides Shotgun footage:
| Issue | Description | Mitigation | |-------|-------------|-------------| | Long first pass | Two-pass encoding doubles time | Use --passes=2 with temp file reuse; consider single-pass VBR with --end-usage=q for rough cuts | | Grain instability | Grain synthesis flickers in very dark scenes | Reduce --arnr-strength to 3 or disable --enable-tpl=1 for those specific shots | | Memory usage | --lag-in-frames=25 uses >4 GB RAM for 4K | Reduce to 16 for memory-constrained workers |
