Shetland is a BBC production (distributed by ITV Studios and BritBox internationally). While HEVC is a legitimate, open-standard codec, the distribution of copyrighted files via BitTorrent or Usenet using the tag "Shetland S07 HEVC" often falls into piracy. Always consider supporting the show officially via BBC iPlayer (with VPN) or BritBox to ensure Jimmy Perez’s final cases get the ratings they deserve.
The only downside to HEVC is computational power. Encoding Shetland Season 7 from a Blu-ray source to HEVC takes roughly 4x longer than H.264. However, for the end-user downloading or streaming the final product, the result is seamless. shetland s07 hevc
