Weboutput file size of H265 vs AV1 for CRF with presets Hello. According to x265 docs When you use slower presets, x265 tests more encoding options, using more computations to achieve the best quality at your selected bit rate (or in the case of –crf rate control, the lowest bit rate at the selected quality). WebJul 22, 2024 · Finally, in FFmpeg, and most encoding tools that deploy the x264 and x265 codecs, there are three switches that control the bitrate. These are: b:v – This sets the overall bitrate. maxrate – This sets the maximum bitrate. bufsize – This sets the size of the Video Buffer Verifier – see here. Let’s start with Constant Bitrate Encoding, or CBR.
