However, when I first compared AV1 encoding times with x264 and x265 in this article, I clocked x264 at 2:09 (min:sec), x265 at 2:18, and AV1 at 50:43.
Still working on the AV1 encoding comparison and have some interesting findings to report.īy way of background, when the Alliance for Open Media (AOM) released version 2.0 in May, Google Principle Engineer and Engineering Director Yaowu Xu published a post on LinkedIn that promised up to 430x speed improvements in AV1. So FFmpeg’s slow AV1 encoding performance on Windows appears to be a compiling issue that can and probably will be overcome, not a codec issue. Though FFmpeg took 50 minutes to produce a test file that both x264 and x265 encoded in about two minutes, the Alliance for Open Media’s aomenc encoder, running the same version of AV1 (version 2) produced the file in about 15 minutes. AV1 encoding is now only 2x slower than x265.
