The film runs 3 hours 6 minutes (186 minutes). Uncompressed, that would exceed 500 GB. An x264 1080p rip might be 12–15 GB. With x265 and 10-bit, the same quality fits into 4–6 GB .
The trade-off: encoding time. A 4-core CPU might take 24 hours to encode Ghajini in x265 at slow preset. The Ci... suffix likely points to a release group (e.g., "CiNEPHiLIA" or similar), indicating institutional encoding knowledge: proper deinterlacing, cropping (removing the 2.35:1 black bars), and scene-detection for keyframes.

The technology (10bit, HEVC, 5.1) is magnificent. The end use (downloading -Ci... rips) is legally gray. But understanding the language is pure knowledge. The film runs 3 hours 6 minutes (186 minutes)
