FFmpeg noise reduction for video and audio. PROACTIVELY activate for: (1) video denoising (nlmeans, hqdn3d, atadenoise), (2) GPU denoising (nlmeans_opencl, nlmeans_vulkan), (3) audio noise reduction (afftdn, anlmdn), (4) film grain removal, (5) low-light cleanup, (6) compression artifact cleanup. Provide concise commands, stronger-by-default settings, and quick tuning guidance.

Remove silent sections from video files using the elegant Remsi approach.
Based on Remsi - uses ffmpeg's silencedetect filter combined with select/aselect filters for clean, efficient processing.
python /a0/usr/skills/remove-video-silences/scripts/remove_silences.py INPUT OUTPUT [OPTIONS]
-n, --noise: Silence threshold in dB (default: -50)-d, --duration: Minimum silence duration in seconds (default: 0.9)--dry-run: Show ffmpeg command without executing# Default settings (-50dB threshold, 0.9s minimum silence - conservative)
python scripts/remove_silences.py video.mp4 video_trimmed.mp4
# More aggressive silence detection
python scripts/remove_silences.py video.mp4 video_trimmed.mp4 -n -25 -d 0.3
# Preview command without executing

Default settings are conservative to avoid cutting voice. Adjust based on your needs:
| Content Type | Recommended Threshold | Min Duration |
|---|---|---|
| Clean studio audio | -50 dB | 0.9s |
| Normalized speech | -45 dB | 0.7s |
| Noisy recording | -40 dB | 0.5s |
| Aggressive cutting | -30 dB | 0.3s |
