The "x265" ("HEVC") (High Efficiency Video Coding) codec is central to the file’s design. Unlike older codecs like x264 (H.264), HEVC reduces file sizes by up to 50% for the same perceptual quality, making it ideal for streaming. x265, an open-source implementation of HEVC, optimizes compression efficiency while retaining detail—especially valuable for Thai media or content with intricate visual textures. This codec supports 4K resolutions, 10-bit color, and HDR (High Dynamic Range), future-proofing videos like Hunger 2023 for next-generation displays.
