If you are watching a heavily compressed version of SONE-012 downloaded from a torrent or streaming on an unofficial site, you will lose all of these features. The 4K is downscaled to 720p/1080p, the BTS is cut out, the chapter markers are stripped, and the audio is compressed to mono or low-quality stereo. To actually use the features listed above, the file must be the untouched original ISO (disc image) or a direct stream from FANZA.
Included on the disc or as a bonus digital download, S1 always includes a gallery of high-resolution photos taken during the shoot. SONE-012
