Chris, if you feel the need to be sarcastic on comments, please refrain from further commenting. If you hated it, dandy! I'm looking for feedback. You may simply not comment if you wish, sirrah.
Not being sarcastic, that was a genuine question. Some people only want to be reassured, some people want things picked apart.
So, to address your video.
First, the lack of the spoken script makes you lose a lot of effect.
Now, the trick really has no logic or motivation. Twenty seconds of shuffling and cutting. One shuffle is all it should take, don't over prove things. The selection is made and you're obviously getting ready to do something with the deck as you display it, due to the amount of fidgeting with the cards.
Then you put all the cards into the box, and ta-da! Is that supposed to be a joke? That may work if you're talking, but it just seems dumb in the video.
Then you obviously have a fair amount of trouble getting the cards back out of the box, a procedure that should be very easy. Makes it seem like you're doing something sneaky there.
Three missed finds. You said you were going to make the card appear in the box, but you just show some cards as if you're changing the trick without saying you're changing it? Need more script there.
Then you pick up the box and fidget with it. Were I watching this, I would assume you're moving something out of view.
Then you do the final reveal. Now, I do like that little move. The box lifting and falling is kind of neat. But why? What's the motivation for that? It's just a stunt, there's no reason for it to happen.
Basically, I think you've got a decent idea with that reveal, but this trick needs a ton of work. From the structure of the trick down to the performance of the sleights.
