Encore was created to scale, and abstract the transcoding power of FFmpeg, and to offer a simple solution for Transcoding - Transcoding-as-a-Service. Based on Google's VP9, [39] AV1 incorporates additional techniques that mainly give encoders more coding options to enable better adaptation to different types of input. This encoder offers three orders of compute scalability (that's more than 1,000 times speed difference from the slowest to the fastest presets) with the most beneficial tradeoff between compute and bitrate efficiency among all open software AV1 re-encoding using ffmpeg, svt-av1 & vmaf. libaom is slow because it's fundamentally a research product - the folks hacking on it are mostly concerned with the workload of encoding a basket of twenty short clips and demonstrating a tradeoff between Bjontegaard scores and increased encode time, and much less on holistically making a usable encoder. MKV is the default container and recommended for most use cases, as it can be easily remuxed into a more compatible format.
