You might ask: Why not just stream it in 4K? Because streaming compression is brutal. A 4K stream on Netflix often sits at 15-25 Mbps, but the audio is compressed, and dark scenes become "banding" nightmares.

This is the video codec. x265 is an open-source implementation of the HEVC (High Efficiency Video Coding) standard, which is the successor to the H.264 (or x264) standard. Compared to H.264, x265 can achieve the same visual quality at roughly half the bitrate or, alternatively, produce significantly better quality at the same file size. For a small 999MB file, using x265 is essential to achieving the "HQ" tag, as H.264 would likely produce too many artifacts at such a low bitrate. Margin.Call.2011.720p.BluRay.999MB.HQ.x265.10bi...
