On one end of the spectrum, you have (often found on anime sites or private trackers) that crush file sizes down to tiny proportions (e.g., a 4K movie in 2GB). While efficient, these often suffer from "macroblocking," banding in dark scenes, and washed-out colors due to extreme bitstarving.
Unlike boutique encoding groups that use Constant Rate Factor (CRF) to prioritize visual consistency across scenes, RARBG frequently utilized Average Bitrate (ABR) or 2-pass encoding for their standard x265 encodes. This ensured predictable file sizes (e.g., exactly 1.4 GB or 2.0 GB). rarbg x265 encoding settings better
