    Description: `[Contains built-in filter] This plugin uses different CQ:V values (similar to crf but for nvenc) depending on resolution, 
     the CQ:V value is configurable per resolution.
     FFmpeg Preset can be configured, uses slow by default. 
     ALL OPTIONS MUST BE CONFIGURED UNLESS MARKED OPTIONAL!
     If files are not in hevc they will be transcoded. 
     The output container is mkv. \n\n`,
