Ffmpeg - fast but bad results, handbrake - slow but good results (lemmy.one)

Hi all,

I have been re-encoding using handbrake’s presets (Matroska hevc 480p/1080p) and results are good for the most part, some issues here and there. I started trying out ffmpeg with cuda and hevc_nvenc and p7 preset. Video quality looks way better but audio is very bad. I am using aac 128k and the audio is very compressed and quite frankly hurts my ears. I started looking into the handbrake options and there’s auto pass through and stereo downmixing, etc. I tried reading the ffmpeg documentation but there is a lot there and I’m not really sure what I’m doing.

tldr; Anyone have tips on getting good quality audio encoding (aac) from my bluray rips?

yes basically handbrake is an easy button but not as powerful as ffmpeg. ffmpeg has aac encoding options, sometimes you can get into easier syntaxes just to make it easier on the mortal mind by first demuxing your source file into individual streams, re-encoding those as needed, then remuxing together. i still have no idea how to get ffmpeg to use cuda/nvenc and also do other things as the syntax becomes arcane to me

Yea easy button means I’m not learning much about the process. I think I just need to take the plunge and learn all about ffmpeg.
