There was a warning that because of Ubuntu 12.04 only an older version of ffmpeg could be added by the ppa (I forgot to copy it) $ sudo apt-get update & sudo apt-get upgrade $ sudo add-apt-repository ppa:jon-severinsson/ffmpeg That is why I tried to install the version from the ppas: See Who can tell me the difference and relation between ffmpeg, libav, and avconv (). I tried you command but got the following error message: One series of tests () shows that the native FFmpeg aac encoder provides better quality than libvo_aacenc.įfmpeg -i input.avi -vcodec libx264 -crf 24 -preset slow -filter:v hqdn3d=4.0:3.0:6.0:4.5 -acodec aac -strict experimental -ab 192k output.mp4 See the FFmpeg and x264 Encoding Guide () for more info. For two-passes, the first pass does not need to encode the audio, and you don't even need to output to a file. In most other cases you should do a single pass with -crf. It does not mean "same quality" () and has been removed upstream.Įncoding with two-passes is generally used if you are targeting a specific output file size. If that is the case, then you can compile ffmpeg (), use a PPA (), or an already compiled static build ().ĭo not use -sameq. I'm unsure if the so-called "ffmpeg" from the repository has this filter. You should use the hqdn3d () filter for noise reduction. I doubt -nr requires two passes to work properly, but I've never used it.
