ace from bottom to top in one shuffle

for the initial part. 0:18, when he takes the top part of the deck, it seems like you see too much white, like he's placing a card underneath and 0:20 when he draws the card, looks like it might not have been from the drop of the deck. how he got the ace to the third space, i can only assume he palmed the shit out of that ace to the point you can only do this trick a couple of times before getting a new deck or this deck is meant for tricks with the ace of spades
