Overall, it's a good trick with some nice ideas, but it could do with tightening up.
In the first minute of the video all that happened was that a card was selected. All the shuffles and cuts that surrounded this selection didn't really add anything, perhaps even detracting from the effect, as they were handled so precisely that they didn't give any feeling of random mixing, which was surely the point. Also, I think many astute members of a lay audience would spot that your strip cuts were false. Given that, they may well conclude that the rest of the shuffling and cutting procedure must also be false. One or two casual riffles and a straight cut would probably seem more convincing as a way of "losing" the selection in this context.
I'd like to see the trick with patter as I don't think it really has much magical impact with captions on the screen. To my mind, the key to this effect, presentationally speaking, is that it's a moment of surprise when the supposed ace is turned over to reveal it's actually the selection. In your presentation, that moment was telegraphed long before it arrived. Then once that first climax fails, the other two reveals lose their impact. I think your routine could work, but I'd need to see it with a more focused presentation to critique it properly.
