Elevated, and from behind, an additional spot was directed at her hair and shoulders.
Then a couple of spots were placed high, and in front of her, to give it that ‘stage lighting’ look.
To ‘further’ the ‘live performance’ illusion, the camera was placed low to the floor and at a distance. Then she was given ‘objects’ to look at when she spoke, which helped keep her head pointed slightly downward (as it would be if she really were on stage).
Lastly, add a little music, crowd noise, and an animated introduction . . . and you got a pretty convincing ‘live’ presentation.
