That video sounds like Fan-ta to me. The same as Santa as in Santa Claus. Jus remove the F and put an S. That is how I always knew it and say it.
Fawn-ta, seems to me like it would sound like 'porn' 'corn' dawn' etc, and I don't hear that in that video.
That's weird. You hear it pronounced the other way too, right? Like, if that's fan-ta, pronounced like "father," then some people pronounce it, like... super midwest. Like "fan-ta," like "fanny."
