Not very many questions tagged tracking at the moment, but they're basically split.
We've got tracking as a likely synonym for audio-recording.
And also tracking as in, "following the movement of" as it pertains to video editing software.
Perhaps tracking should be a synonym for audio-recording and [motion-tracking] or [tracking-motion]? The two video related questions both involve the after-effects tag as well. Is tracking only related to that adobe product? or is it just coincidence at this point?
