Predefined Quality Profiles in Different Versions of HEVC Encoder - Influence of PC Architecture of Processor

Abstract

This paper describes a coding efficiency of the High Efficiency Video Coding (HEVC) encoder with different predefined quality profiles. To increase the encoding speed of the video at the same bitrate we can use either other implementation of the encoder or we can set different predefined quality profiles. The x265 is the implementation of the coding standard HEVC. This article complements of our previous exploration of predefined x265 profiles. There is explored the influence of processor architecture and version of x265 implementation on the speed of encoding and on the performance of video quality.
