Abstract

The H.265/HEVC is the state-of-the-art video compression standard, which allows the bitrate reduction up to 50% compared with its predecessor, H.264/AVC, maintaining equal perceptual video quality. The growth in coding efficiency was achieved by increasing the number of available intra- and inter-frame prediction features and improvements in existing ones, such as entropy encoding and filtering. Nevertheless, to achieve real-time performance of the encoder, simplifications in algorithm are inevitable. Some features and coding modes shall be skipped, to reduce time needed to evaluate modes forwarded to rate-distortion optimisation. Thus, the potential acceleration of the encoding process comes at the expense of coding efficiency. In this paper, a trade-off between video quality and encoding speed of various H.265/HEVC encoders is discussed.
