-" mode.\n"\
-"\n"\
-" For CBR 320kbps (highest quality possible from the preset switches):\n"\
-"\n"\
-" \"preset=insane\" This preset will usually be overkill for most\n"\

-" regard to filesize, this is the way to go.\n"\
-"\n"\
-" For ABR modes (high quality per given bitrate but not as high as VBR):\n"\
-"\n"\
-" \"preset=<kbps>\" Using this preset will usually give you good\n"\
-" quality at a specified bitrate. Depending on the\n"\
-" bitrate entered, this preset will determine the\n"\
-" optimal settings for that particular situation.\n"\
-" While this approach works, it is not nearly as\n"\

-" Warning: with the current version fast presets might result in too\n"\
