    -h, --help       Show this help

Examples:
    mute.sh input.mp4 output.mp4         # Remove audio, copy video
    mute.sh input.mp4                    # Creates input-muted.mp4
    mute.sh -c input.mp4                 # Same as above (explicit copy)
    mute.sh -v libx264 input.mp4         # Re-encode with H.264
    mute.sh -y *.mp4                     # Batch mute, overwrite existing
