On the other hand, low values will also result in high bitrate producing high-quality videos at the expense of file size.Ĭonsider a file big_buck_bunny.y4m with a file size of 7 GB. The higher the value, the higher the compression, although this may lead to quality loss. The Constant Rate factor (CRF) is the default quality setting for x264 and x265 encoding. Using the CRF of values between 0 and 51 should provide the best compatibility for x265 codecs.
