![]() ![]() For 4k fps 60 resolution, I use a bitrate of 2mb/s, the quality seems correct but I can't really check because it takes 15s to decode a frame. ![]() For DVD resolution (720x576), I use a bitrate of 650kb/s.Instead, I compile FFmpeg from source: git clone -depth 1 Ĭommit ef14518388c0a41c1d3b992f75d5886c9da33832Ĭmake -G "Unix Makefiles" -DENABLE_TESTS=OFF -DENABLE_NASM=on. apt-get install ffmpeg libaom0 libaom-dev nasm yasm libx264-dev libx265-dev libnuma-dev libfdk-aac-dev libopus-dev libass-dev libdav1d-dev libmp3lame-dev libvorbis-dev libvpx-dev I installed FFmpeg and libaom from apt but I don't recommend doing this because it is better to use the latest AV1 encoders. I film with my iPhone in 4k 60 fps hevc and I don't have a computer that can play these videos so I also scale down the resolution. I encode my videos with libaom to get smaller files for a given quality because it takes a finite time to encode and I will store the videos forever. In pass 2, libaom uses 2 cores at 100% and svt1-av1 uses the 16 cores at 100%. I usually encode videos in 2 passes, libaom uses my 16 cores at 33% in pass 1 while svt-av1 uses the 16 cores at 100%. The svt-av1 encoder is optimized for speed and produces bigger files than libaom. Libaom is the reference codec, it produces smaller files than svt-av1 but it is slow. I don't encode many videos but I want to try the newest video and audio codecs:ĪV1 is implemented in libaom and svt-av1.
