How to best record a video over a backing track

[twelfth_hour]

Hi there,

I am starting a new YouTube channel, in which I make educational / comedy raps over the top of a rap backing track.

I have zero experience of making videos. I'm just wondering if I should:

(a) Record all audio separately perhaps in a recording studio and then mime over the top of that when recording the video,

OR

(b) Just play the backing track in the room and then recording the rap live over the top while filming at the same time.

Obviously either of those could work, but I was wondering what would produce the most professional sounding / looking result.

Thank you in advance.
