Shrinking X265 _hot_ -

and Intel QuickSync are faster than CPU x265, but they produce 20–40% larger files for the same visual quality. For shrinking, GPU encoding is the enemy.

In the world of digital video, few codecs have inspired as much devotion and frustration as x265 (the open-source implementation of H.265/HEVC). Praised for its ability to halve bitrates compared to H.264 while maintaining similar quality, it is the gold standard for archiving 4K, HDR, and high-bitrate Blu-ray rips. shrinking x265

If you are achieving smaller than that without denoising, your eyes are missing artifacts. Shrinking x265 is a legitimate skill—one that preserves your hard drive space and bandwidth. But it demands respect. The difference between a "transparent" encode (looks identical to source) and a "trash" encode (blocky, waxy, banded) is just a few CRF points or a single misconfigured psy-rd flag. and Intel QuickSync are faster than CPU x265,
