Automatic Prediction

21st Century Playing Card Prediction. The performer caught without props, grabs a piece of paper and writes down a prediction, which is entrusted to an audience member for safekeeping. He explains that he anticipated such a situation, recounting how he shuffled a deck of cards weeks ago, then dealt them one by one on a table while being filmed. He proceeds to play the recorded video, demonstrating how it can be paused and resumed. He holds his cellphone with the screen facing down. A participant pauses the video at any point, flips the phone over to reveal a playing card on the screen. The prediction is revealed to perfectly match the chosen card.
