New Hampshire Swimming hole location help.

I'm hoping someone here can help...

At 1:26 of this video shows a swimming hole with a small ledge to jump off of. The description of the vid says it was filmed either Arruthusa Falls of Franconia Falls. I've been to both of these places and can't recall seeing this...but I want to go there.

So if anyone recognizes this place could you let me know. Thanks!
