"High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, designed as a successor to the widely used AVC (H.264 or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate."
https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding

10-bit color depth should ALWAYS be used when encoding HEVC (x265), because it saves bandwidth and results in higher quality per bitrate. Even if the source is only 8-bit, like regular BluRays are, 10-bit encoding should be used for the reasons stated. Regular BluRays are encoded in H264, not H265 (HEVC). There's a new disc format called "Ultra HD Blu-ray" ("4K Ultra HD"), which is encoded in H265, with 4K resolution. Unless the source of an encode is this new format, it's in 8-bit color depth.

"... encoding pictures using 10-bit processing always saves bandwidth compared to 8-bit processing, whatever the source pixel bit depth."
