| Metric | Observation | |--------|-------------| | | >95 % of the releases are remuxed from the original Blu‑ray source, meaning no generational loss. When re‑encoding is necessary, the default is x264 CRF 18 (or x265 CRF 20) which retains visual fidelity while cutting file size by ~30 %. | | Audio | Original 5.1 or 2.0 audio tracks are preserved (AAC, AC‑3, or DTS). In a handful of releases, a lossless FLAC track is included for audiophiles. | | Subtitles | Clean, well‑timed .ass files are the norm; the forum maintains a subtitle‑quality checklist (no overlapping lines, proper fonts). When community translations are used, they are labeled clearly. | | Container | MKV is the default, ensuring maximum compatibility (Matroska supports multiple audio/subtitle tracks, chapters, and attachments). | | File size | Because of the remux‑first approach, 1080p releases are typically 10‑15 GB per season (≈2 GB per episode), which is comparable to official releases but far lower than many “raw” torrent dumps. | | Checksum integrity | All torrents are shipped with an MD5/SHA‑256 hash. Community volunteers regularly verify these after upload. | hikaru nagi forum repack
