I know the feeling of wanting to do as much as possible for your spectators, and the feeling of wanting to get through the trick quickly as to minimize the chance for messing up, however, limited time for the video should not equal going through the trick and moving as quickly as humanly possible, it should mean doing less, but with better presentation.
Several things that might help you for the future:
I watched your first trick a few times, and my biggest advice is to just relax, slow down, and let them enjoy the moment. You were leading the spectator way too much. Even the simple thing of how he should put his hand out directly above the table, you seemed very very forceful. Just simply say, "could you please hold out your hand?" However, ultimately, if in the end, you are just going to have him cover the card with his hand on the table, there is no need for him to just hold his hand out there and wait. If you were to rest the card on top of his hand, ok, but after showing him the "7d", you can put it face down on the table in front of him and then just simply, "please cover that with your hand so I wont be tempted to try and steal it from you," etc...
Also, I would suggest that you do not use a joker. Most people know a standard deck of cards come with two jokers and should be suspicious of your choice. (even though they look different).
You look really comfortable with a deck of cards. You are very smooth with your cuts, in the hands shuffles, etc... which shows that you put in your time to polish your technique. That is very important. However, do not let it overshadow your performance. Although I am speaking from a magician's point of view... the card handling took the majority of the my attention away from the actual trick itself and it left me wanting a lot more out of your basic "performance ability."
Perhaps you do things differently when not shooting for a school video, but from what I have seen, try to experiment with the following:
1: slowing down while executing your sleights. You execute your sleights very quickly and do not allow any downtime before proceeding through the trick. I used to do this because I felt that if I just waited there, someone would notice that I did something fishy. Your technique is good, have confidence in it, and just play it off slowly.
2: build up to the moment of the "magic" and let them absorb it before moving on. Your routines/ tricks all had the same "quick pace" with very small pauses, and most of the time, I felt the pauses were at the wrong time.
Here is just one simple idea that can make your ultimate transpo a bit better.
After placing "their card" into their hands, and you show your favorite card on top of the deck. After turning it back over, take it into your hand, put the deck down completely, and mimic exactly what you had the spectator do. For example, if hey are holding the card between their hands, you should do the exactly same thing mirroring them. Then, add a simple subtlety by saying, "now switching these two cards would be impossible, but that's what magic is all about," then take a small peak at the card you are holding and say something like, "hmm, still need a few seconds for this to work I guess," then, slowly reveal that their card is now in your hands, and ask them to slowly peak at the card left in their own hand.
The sleights have already been done, and you are way ahead of schedule, so milk the safety of the situation, and put 100% into your performance. Do anything you can to make the "reveal" part of the trick as memorable as possible. After all, they are not in a position that can be in awe of your technical skill. I as a magician can praise your technical skill and your ability in your sleight of hand. As a spectator however, that is all behind the scenes, so if you do not do everything in your power to make the part of the presentation a spectator does get to witness/ enjoy/ understand, then you are selling yourself short of the applause you deserve.
Just my two cents.
