Because the show cuts rapidly between these timelines to build tension, artifacting or poor color reproduction from sub-par video files can ruin the carefully crafted atmospheric immersion. The Power of x265 (HEVC) Encoding

Unlike a "WEB-DL" (direct download untouched), this WEBRip has been re-encoded. While purists prefer WEB-DLs, ION265’s filtering process often reduces the "banding" (visible color stripes in dark scenes) present in the original Kocowa or Viki streams. For a show with time-travel transitions and dream sequences, this results in a cleaner viewing experience on large TVs.

: Refers to the open-source library used to encode the video into the High Efficiency Video Coding (HEVC/H.265) format.

As indicated by the "KOREAN" tag, the primary audio track embedded in this release is the original Korean dialogue, typically encoded in high-quality AAC or AC3 stereo/surround sound.

The "WEBRip" component is the first critical specification. It indicates the of the video file.
