OptiHero

Clone Hero chart optimizer. OptiHero converts common Clone Hero chart formats to more efficient ones and removes unnecessary files.

• Audio files are converted to Opus 96kbps/48kbps (Supported in version 1.0+)
• Image files are converted to JPG (Quality 70). Album cover is scaled to 500x500, background is scaled to 3840x2160.
• Video files are converted to WebM (libvpx crf=26 maxrate=2M, no audio, max 720p).
• song.ini, notes.chart and notes.mid are kept intact. All other files not used by the game are removed.
