A database focused media conversion utility that converts video files to the HEVC video codec with a focus on reducing disk usage in media libraries. This  
script attempts to be as safe as possible, however encoding to HEVC is a lossy operation. though it should be unnoticeable it is recommended to test first.  
Backups are encouraged.  

optional arguments:
-h, --help            show this help message and exit  
--crf int             CRF parameter to be passed through to ffmpeg, determines quality and speed with lower values being slower but higher quality (not  
                        for NVENC)  
--errors, -e          list errors  
--database DATABASE   name of database to be used  
--focus PATH, -f PATH  
                        immediately begin conversion on target directory  
--list-paths, -lp     list tracked paths  
--list-blacklist-paths, -lbp  
                        list blacklisted paths  
--low-profile         for weaker devices, convert to 4-bit HEVC including downgrading 10-bit hevc  
--number NUMBER, -n NUMBER  
                        transcode from tracked paths limit number of files to be converted  
--nvenc               transcode using NVENC compatible GPU  
--height HEIGHT       Height of the output resolution to be used for conversion  
--preset PRESET       string for ffmpeg paramater, accepts ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow and placebo,  
                        slower speeds have a higher filesize and better quality  
--track PATH, -t PATH  
                        add a new path to be tracked  
--blacklist PATH, -b PATH  
                        add a blacklist path to be excluded from scans  
--saved-space         display HDD space saved by transcoding into x265  
--scan, -s            scan tracked directories for new files  
--quiet, -q           only produce minimal output  
--verbose, -v         produce as much output as possible  
--vbr VBR             Set the Variable Bitrate for the encoding pass, this will adjust NVENC quality  
--minrate MINRATE     Set the minimum rate for Variable Bitrate mode  
--maxrate MAXRATE     Set the maximum rate for Variable Bitrate mode  
--rate-threshold RATE_THRESHOLD  
                        Set the minimum kbps files must have in order to add to processing list during scan  
--rate-ceiling RATE_CEILING  
                        Set the maximum kbps files can have in order to add to processing list during scan  
--height-threshold HEIGHT_THRESHOLD  
                        Set the minimum height files must have in order to add to processing list during scan  
--height-ceiling HEIGHT_CEILING  
                        Set the maximum height files can have in order to add to processing list during scan  
--force-encode        force HEVC re-encode  
--clear-all           clear the library of all files  
--clear-skipped       clear the library of skipped files  
--clear-incomplete    clear the library of incomplete files  
--clear-complete      clear the library of complete files  
--clear-failed        clear the library of failed files
