The preset parameter governs the efficiency/speed I'm reading though the FFmpeg guide on encoding AV1 and under the CRF section for SVT-AV1 it states: "For source files of 1080p and 720p av1 otimization is not optimal, most of the time is better to go with the H265 for better vmaf/size ratio. Jul 24, 2023 · The choice between X264, X265, and AV1 should be made based on specific requirements, including file size, encoding speed, and the trade-offs between compression efficiency and visual quality, rather than relying on broad generalizations. 265 = 5 pixles compression Something like that which is how it manages to make the file size smaller, but if you turn up the quality you can match the X. If we put this context with our compression ratio, this would mean that AV1 can offer higher compression ratio at similar visual quality as H. Av1 does voodoo (professional term The crf parameter governs what the file size will be. 1 percent better compression compared to H. " I have a bunch of H. AV1 is superior to HEVC in terms of file size, offering better compressibility by 34%.
