So I tried: ffmpeg -hwaccel nvdec -y -hide_banner -i input.mp4 -vf scale=-2:480 -movflags faststart -pix_fmt yuv420p -c:v h264_nvenc -b:v 200k -maxrate 2M -bufsize 1M -rc-lookahead:v 30 -rc:v vbr_hq -preset slow -profile:v high -level 5.1 -an h264_nvenc.mp4īut this gives me an output with worse overall quality, and in complex parts, things gets worse: This output quality is acceptable for my needs:īut I would like to enjoy hardware acceleration, it is way much faster. 5.I'm compressing some videos for archiving, and I came to this configuration which gives me a nice overall quality on a small size: ffmpeg -threads 4 -y -hide_banner -i input.mp4 -vf scale=-2:480 -c:v libx264 -b:v 200k -preset slow -tune animation -movflags faststart -pix_fmt yuv420p -an -f mp4 -pass 1 NULįfmpeg -threads 4 -y -hide_banner -i input.mp4 -vf scale=-2:480 -c:v libx264 -b:v 200k -preset slow -tune animation -movflags faststart -pix_fmt yuv420p -pass 2 2-pass-x264.mp4 hevc_nvenc NVIDIA NVENC hevc encoder (codec hevc)ĭEBUG 01:45:09.807 configuration: -prefix=/root/ffmpeg_build -pkg-config-flags=-static -extra-cflags=-I/root/ffmpeg_build/include -extra-ldflags=-L/root/ffmpeg_build/lib -extra-libs='-lpthread -lm' -bindir=/root/bin -enable-gpl -enable-libaom -enable-libass -enable-libfdk-aac -enable-libfreetype -enable-libmp3lame -enable-libopus -enable-libvorbis -enable-libvpx -enable-libx264 -enable-libx265 -enable-version3 -enable-static -disable-debug -enable-libwebp -enable-libspeex -enable-fontconfig -enable-libxvid -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libtheora -enable-libvo-amrwbenc -enable-gray -enable-libopenjpeg -enable-libvidstab -enable-libsoxr -enable-frei0r -enable-libfribidi -disable-indev=sndio -disable-outdev=sndio -enable-libzimg -enable-librtmp -enable-libmfx -enable-nonfreeĭEBUG 01:45:09.807 libavutil 56.
