- Fixed standard encoding path to apply all SVT-AV1 config variables (fast-decode, enable-overlays, aq-mode, enable-qm, qm-min, qm-max, tile-columns were previously ignored outside grain synthesis mode) - Fixed grain path to use $svt_aq_mode variable instead of hardcoded value - Removed scd=1 from both encode paths (no-op in SVT-AV1 3.x, generated warnings) - Updated bundled ffmpeg to N-123918-gf7ca6f7481 (April 2026 snapshot, SVT-AV1 3.1.2) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
