By using x265 with slow presets ( slow , slower , or veryslow ), RMTeam produces files that are often indistinguishable from much larger x264 files to the average viewer.

: x265 can achieve the same visual quality as x264 at roughly 50% of the bitrate ( Ant Media ).

| Feature | x264 (H.264) | x265 (H.265 / HEVC) | | :--- | :--- | :--- | | | Good | ~50% better at the same quality | | File Size | Larger | Much smaller (e.g., 2GB vs 4GB) | | Encoding Speed | Fast | 4-10x slower | | Playback Hardware | Works on almost any device (old phones, smart TVs, PCs) | Requires newer hardware (post-2016) or a powerful CPU/GPU |
