Package managersĬargo: cargo install av1an Manual installation There are also pre-built Docker images which include all dependencies and are frequently updated.įor Windows users, prebuilt binaries are also included in every release, and a nightly build of the current master branch is also available. InstallationĪv1an can be installed from package managers, cargo.io, or compliled manually. vpxenc, SvtAv1EncApp) from the list above. If you use a package manager to install encoders, check that the installation includes an executable encoder (e.g. Note that Av1an requires the executable encoder. Needless to say, it always massively outperformed h264_nvenc in terms of quality for a given bitrate, while also being slightly faster.Av1an -i input.vpy -v '-cpu-used=3 -end-usage=q -cq-level=30 -threads=8 ' -w 10 -target-quality 95 -a '-c:a libopus -ac 2 -b:a 192k ' -l my_log -o output.mkv Supported encodersĪt least one encoder is required to use Av1an. Using the ‘slow’ preset, av1_nvenc outperformed hevc_nvenc in terms of encoding speed by 75% to 100% while performing above tests. At higher bitrates I had a hard time finding differences between the two encoders in terms of subjective visual quality. It produces fewer artifacts and the ones it does produce are less jarring to my perception. In terms of quality at low bitrate cbr settings, it seems to outperform it even. The encoder seems to be trading blows with hevc_nvenc. AMD is also expected to support Intel’s AV1, which has been gaining popularity month after month since its release.

The relationship between AMD and OBS was disclosed last Friday during the AMD RDNA 3 unveiling. In order to compete with NVIDIA and their GeForce RTX 40 series GPUs, OBS Studio, one of the top free streaming software programmes, just added AMD to its Diamond Tier sponsors list. Early reviews talked about the performance benefits of lower bit rates, but the surprise revelation is that it performs up to 100% better than the conventional HEVC encoding (H.265).įor users of OBS, this revelation is fantastic news. The NVENC AV1 video encoder from NVIDIA is now supported by FFmpeg, a commonly used command tool for video processing.
