The mp4 extension refers to the MPEG-4 Part 14 container. When a release claims "extra quality" but stays within the MP4 format, it tells you specific things about the file’s compatibility and structure.
While many releases cap out at 720p, the extra quality iteration is almost exclusively native or an untouched 1080p Blu-ray remux . This ensures that every frame retains the original grain and texture intended by the director, rather than a heavily smoothed digital mess.
The user is not searching for a generic video. They are searching for a specific, rare title from a niche label focused on a specific fetish (paizuri/breasts).
