Usage:
garmin_varia_transcode.sh [options]
Options:
-s, --source, --input DIR Source directory or single file (default: current directory)
-d, --destination, --output DIR Destination directory (default: current directory)
--mode MODE Encoding mode (default: hardware); see Encoding Modes below
--crf N CRF value for quality/compat modes (lower = better; default: 20/19)
--no-overwrite Skip files that already exist at destination (default: overwrite)
--dry-run Print actions without writing files
--no-recursive Process only the top-level source directory (default: recursive)
--extensions LIST Comma-separated video extensions (default: mp4,mov,avi,m4v)
--verbose Log each operation with timestamp; show ffmpeg/ffprobe output
--delete-source Delete source file only after strict post-encode validation
--keep-going Continue after source-file failures (default: stop)
--unattended Preset for long runs: --delete-source + --keep-going
--no-apple-repack-fallback Disable macOS avconvert fallback for unreadable MP4/MOV sources
--apple-repack-fallback Enable macOS avconvert fallback (default)
-h, --help Show this help
Encoding Modes:
hardware Uses hevc_videotoolbox (Apple Silicon / Intel Mac GPU). macOS only.
~4-5s per 30s clip, ~35W (measured on Apple Silicon MacBook Pro).
Best choice when running on battery or transcoding large libraries.
Output quality is good for dashcam/action footage.
Falls back to an error on Linux or if videotoolbox is absent.
auto Like hardware on macOS with videotoolbox, otherwise falls back to quality,
then compat. Safe cross-platform default when the machine is unknown.
quality Uses libx265 (software HEVC, CRF 20). Platform-independent.
~50s per 30s clip, ~80W (measured on Apple Silicon MacBook Pro).
Best compression ratio and quality for archival, high-resolution, or visually
complex sources (e.g. cinema, screen recordings).
Overkill for dashcam footage; prefer hardware or auto for those.
compat Uses libx264 (software H.264, CRF 19). Maximum player compatibility.
Use when the destination player cannot decode HEVC (older TVs, Android 4.x,
web browsers without HEVC support). Larger files than HEVC modes.
Behavior:
- Output is always .mp4 (H.264 or HEVC depending on mode, always Apple-compatible)
- HEVC outputs are tagged hvc1 for QuickTime / Apple Photos compatibility
- Metadata is restored from source to output with exiftool
- Garmin camera model is also mapped to standard Make/Model tags for compatibility
- Inferred lens metadata is written from Garmin's declared 140-degree FOV
- Transcoding encoder/mode is written in metadata (Software)
- Original directory structure is preserved under destination
- When --source points to a file, only that file is processed
- JSON sidecar files found in source are copied 1:1 to destination
- telemetry_manifest.json is created in destination as a placeholder contract
Examples:
./garmin_varia_transcode.sh -s SampleFootage -d /Volumes/Archive
./garmin_varia_transcode.sh -s SampleFootage -d encoded --mode auto
./garmin_varia_transcode.sh -s clip.mp4 -d encoded --dry-run --verbose
./garmin_varia_transcode.sh -s SampleFootage -d encoded --mode quality --crf 18
./garmin_varia_transcode.sh -s SampleFootage -d encoded --mode compat
./garmin_varia_transcode.sh -s SampleFootage -d encoded --delete-source
./garmin_varia_transcode.sh -s SampleFootage -d encoded --unattended
