I'll be concise:
while I can get to motion tracking I don't have the same menus I see on specific tutorials that seem to be running 2.8. odd.
I can Ctrl+A and place markers all over.
I cannot get them to track and show tracers when scrubbing left or right, regardless of which track button I'm using (command T, or Shift command T).
Everyone seems to have a menu next to "help" that shows motion tracking as an option. I've got nothing but tabs up there (layout, modeling, sculpting, UV editing, etc).
