Av1ans scene detect is stupid fast and the process of chunking itself has basically no overhead. Then av1an splitted the source file and created 4 chunks in a temp directory (which is bad). With one instance I roughly archive 0. This is first release with all main functionality. It's going to produce more efficient encodes because it uses chunk-based encoding to reach the required VMAF for every single chunk, but this is also slower because every chunk will be re-encoded until the VMAF target is reached. Kind of annoying, but at the end of the day it’s not the only way to have Docker working on a machine, even on other platforms, and this is what we’ll talk about. 4, you can simply use the -crf 0 argument. n00mkrad commented Sep 30, 2021.
