WebM or OGG?
Keep WebM when
- The picture matters too. The OGG holds only the sound.
- The sound should stay as it is. WebM to OGG loses a little more.
Pick OGG when
- A game, an app or a website asks for OGG files.

Questions
Which quality should I pick?
The commands use quality 6, a common middle ground between size and sound. Change -q:a 6 to a lower number for a smaller file or a higher one for more detail, 0 to 10.
What does the copy line do?
It works when the WebM sound is Vorbis; ffprobe clip.webm shows the codec. The copy line moves the sound into an OGG as it is, so nothing is lost. For Opus sound it would write an Ogg Opus file, so use the first line.
Why does the Mac line use a different encoder?
Homebrew's FFmpeg has no libvorbis, so the Mac line uses FFmpeg's own Vorbis encoder; -strict -2 turns it on. It writes stereo only, so -ac 2 makes a mono file two channels. Windows uses libvorbis.
Do the title and artist stay?
With the FFmpeg lines, yes: FFmpeg carries tags such as the title across to the OGG.
