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?

Handbreak is just a GUI for FFmpeg, so the only thing it could be is your settings. Are you using the -c:a copy option with FFmpeg to copy the audio instead of transcoding it?

I’ll give copy a try instead of transcoding and see how that works. I wanted the video, audio, and container format to be the same across my library, so as long as it’s always using the same codec across my movies, that should be fine.
