x265 Encoder

x265 HEVC Encoder is a professional-grade and complex piece of software created to provide users with the means of converting their videos to High Efficiency Video Coding files, through Command Prompt.
Since the utility functions through a command line interface, this may deter many users from trying it, due to the more complicated methods of processing files and the experience required to properly handle such programs. However, advanced individuals will most likely have little to no trouble with it, its usage resembling that of most codecs.
Nonetheless, x265 HEVC Encoder offers users extensive documentation, requiring them only to type the ‘-h’ (help) command in order to exemplify its proper syntax, as well as the input and output options, available quality reporting metrics, threading, performance and presets.
Moreover, it shows users the arguments corresponding to various analyses and coding tools that they can work with, UUI and bitstream options, loop filters, rate control and adaptive quantization.
x265 HEVC Encoder is able to work with YUV or Y4M source files, while subsequent to the conversion operation, it outputs them as raw HEVC bitstream videos. The maximum supported resolution reaches goes as high as 8192 x 4320. At the same time, it aims to obtain compression ratios as high as 1000 to 1.
While the codec may be based on x264, it brings a set of new options and functions that are meant to improve the way users encode their videos, as it preservers a high level of video quality, but manages to double the compression ratio of its predecessor, a feature which is bound to make increase its appeal as time goes on.
