HEVC is particularly kind to films like Trainspotting , which feature a combination of heavy film grain (intentional, to give a gritty documentary feel) and high-contrast lighting. The algorithm preserves the grain structure without smearing it into "blocky" artifacts. For the collector, HEVC represents the perfect trade-off between storage space and fidelity. The cryptic tag -CM- is likely the release group signature. In the shadowy world of scene releases and P2P encoding, groups tag their work. While less famous than groups like D-Z0N3 or CtrlHD , CM (likely standing for "Conspiracy" or a personal encoder's initials) is recognized in certain archival circles for specific parameters.
Older encodes of Trainspotting used AVC (H.264). While AVC is excellent, HEVC is roughly twice as efficient. What does that mean for Trainspotting.1996.1080p.BluRay.HEVC -CM-.mkv ? It means that a file which would have required 12-15 gigabytes in AVC can now achieve visually lossless transparency at 5-8 gigabytes. Trainspotting.1996.1080p.BluRay.HEVC -CM-.mkv
