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?
I am 90% sure handbrake is an ffmpeg front end. If you dig around in the config files or source repo you can probably find the exact settings used.
My understanding is that handbrake uses some of the ffmepg libraries but is not on top of the ffmpeg binary, so things do that translate directly. I’ll check out the source code and see what I can figure out about the preset to ffmpeg option mapping.
