Media Transcoding (FFmpeg)
Overview
Use FFmpeg presets to normalize video outputs for web streaming, mobile delivery, or archival quality. Your hf-videos repo already includes a simple bash script and a more advanced Python script with presets, backups, and logging.
Quick Start (hf-videos)
./ffmpeg_convert.sh check
./ffmpeg_convert.sh web_standard "My Video.mp4"
./ffmpeg_convert.sh batch_web_standard
Outputs are written to converted/ with backups in backup/ and logs in conversion.log.
Preset Summary (hf-videos)
- web_standard: 1080p max, CRF 23, 128k audio,
+faststart
- web_high: 1080p max, CRF 20, 192k audio
- mobile: 720p max, CRF 25, 96k audio
- ultra_compact: 480p max, CRF 28, 64k audio
- archive: original res, CRF 18, 256k audio
All presets use H.264 + AAC with +faststart for streaming-friendly MP4s.
Batch Workflow
- Run a single-file conversion first to validate output.
- Run batch conversion once the preset is confirmed.
- Verify output sizes and playback.
Batch commands:
./ffmpeg_convert.sh batch_web_standard
./ffmpeg_convert.sh batch_mobile
./ffmpeg_convert.sh batch_ultra_compact
Advanced Script (convert_video.py)
Use convert_video.py when you need:
- Progress monitoring
- Metadata inspection
- Overwrite control
- Preset listing and batch automation
python3 convert_video.py --list-presets
python3 convert_video.py --file "My Video.mp4" --preset web_standard
python3 convert_video.py --preset mobile --overwrite
Output Conventions
- Converted files use suffixes like
_web_standard.
- Backups preserve original filenames.
- Logs go to
conversion.log for audit and troubleshooting.
Troubleshooting
- FFmpeg missing:
brew install ffmpeg (macOS) or install from ffmpeg.org.
