The user might be referring to an adult content file available on a torrent or hosting site. The mention of 720p and HDRi might be part of the file's metadata to indicate its resolution and quality. The HDRi part is a bit confusing here because HDRi is typically more related to 3D rendering or photo-realistic materials in 3D modeling, not something commonly used in standard video files. Unless it's a high dynamic range video, which is different but not usually denoted as HDRi. Maybe it's a typo or a misnomer.
