Custom AAC profile with VBR
Posted: Fri Mar 29, 2019 3:21 pm
Greetings, all. I'm fairly new to MakeMKV and just discovered custom profiles. I've been using MeGUI for audio conversion, but if I can set up a profile the way I want, it will make my life a whole lot easier. What I want is a conversion of all audio tracks using FDK-AAC LC with VBR quality=4. No downmixing, resampling, or other funny business. Whatever it is, it is. Just in AAC.
I've had a look at aac-st.mmcp to use as a template, and frankly I can't make heads or tails of it. It looks like it's using fdk-aac as the default, although I do see some ffmpeg blocks as well, which I don't want. I also see some blocks for HE-AAC and HE-AACv2, and I don't want those either. I want to stick to AAC-LC for higher bitrate encoding. Is it safe to delete those blocks I don't want?
Lastly, I don't see any <extraArgs> examples for setting quality or mode. I assume it's using the FDK default of CBR 64k, but I can't really tell. If I were doing it on a command line, I would want the --bitrate-mode=4 argument. Is that what I would add to the <extraArgs> section, or would the syntax be different? Would I add it to an existing line after profile=LC, or would I make a new line for it like Afterburner is?
