Abstract
- This paper deals with the impact of constant rate factor value on the objective video quality assessment using PSNR and SSIM metrics. Compression efficiency of H.264 and H.265 codecs defined by different Constant rate factor (CRF) values was tested. The assessment was done for eight types of video sequences depending on content for High Definition (HD), Full HD (FHD) and Ultra HD (UHD) resolution. Finally, performance of both mentioned codecs with emphasis on compression ratio and efficiency of coding was compared.
