Good first videos. If you enjoy doing them, I recommend that you continue. You may have more fun if you get some video editing software, but I have no suggestions, except Apple iMac. Sorry.
Specific Suggestions (using the Crane as an example):
1. Try to keep the paper on the table. Your focus is beginners, and it is easier to follow the folding when the paper is fairly stationary on a flat surface.
2. Consider that much of Origami is symmetric and try to show that in the instructions (without actually saying it). For example, "Fold the top point down. Unfold it. Now turn the paper over and fold the top point down on this side, and unfold."
3. Try not to apologize or make side comments. Instead, simply make your instructions clear, simple, and use small steps.
4. Petal fold: for the purpose of a beginner, when you learn to make a petal fold you use the folded crease as a pivot point, then slowly pull the flap up, while correcting the side flaps inward. Then turn the paper over and repeat these steps (and show the steps in the video). However, I like you petal-fold method, in practice. I haven't asked beginners which one they understand better.
5. When you fold flaps to the middle, do it slowly to show if you are folding the point or the edge to the middle.
6. The conventional term for the "things" that become the head and tail (etc.) are called "flaps" ...
7. It is not clear what you are doing to folds the head. Tell the beginner that it is called a reverse fold, and slowly show them how to do it.
8. Folding the wings down... was magically ....

You need to explain all of the steps - pull the wings apart gently to flatten the middle... Otherwise you are only showing us how Jake folds a crane, and I don't think that was your intention.
I admire people who are willing to take the time to make videos to show the rest of us how to fold models. I personally don't have the patience or talent that you've shown, to pull it all together. And there are lots of models that people want help with, so I look forward to seeing more of your instructional videos.
Thanx,
