MP3 is fine for distribution. The rub is usually if you're trying to play the file on a device, since those may be stricter about all this and not like it. Most AMVs are targetted for PC playback, so the issue is moot - pretty much everything is totally okay with MP3 audio in MP4 files these days (assuming that you would be using MP4 as the container and not MKV).
My underlying point is that FFmpeg's native AAC encoder (-c:a aac
) is not really that good, so you'd get better quality results by using MP3. If you're really worried about it, go ahead and use -c:a aac
instead of -c:a libmp3lame
, just give it a high enough bitrate.
Ooookay, so I need a different build of ffmpeg (not Mac version) under wine (which in my case means PlayOnMac), it should have been installed already with the amvpack? I tried finding it, but no such luck... If it is not installed, which build should I install to make sure it has avisynth support?
I don't know about it being installed with the amvpack, but you can get FFmpeg builds for Windows from here (grab the latest 'static' build from the 32-bit download column):
Virtually all Windows builds of FFmpeg have AviSynth support enabled. It's trickier/almost impossible to find non-Windows builds with it enabled (Debian-unstable and some AUR PKGBUILDS notwithstanding, but those are both Linux, not Mac), because many packagers are still under the false impression that the --enable-avisynth option only works on Windows - it used
to be a Windows-only option, but that changed in 2013. Or they look at AvxSynth, see that very very few plugins were ever ported to it, and use that as justification to not enable it.
So while Windows (and Wine users) will almost always have builds with AviSynth support enabled, OSX and Linux users that want a native build typically have to compile FFmpeg themselves to make sure that the build can talk to AvxSynth. I cover installing AvxSynth in the step-by-step guide in the Mac section
, for those that are feeling somewhat adventurous (I cover getting Homebrew installed in the first post in that thread).
