Hello there, Tnigz39, and welcome to Bricksinmotion.com! First off, I'd suggest you read the Bricks In Motion Beginners Guide and Rules.
Now, about your stop-motions. What camera and animation software do you use? If you don't already use one of these, I would suggest Monkeyjam or HeliumFrog as an animation software. I would also suggest raising your frames per second, or fps. (Here is a good explanation of what fps is).

Also you will want to find a good way to secure your camera down so it doesn't bump around during the video.

So there are a couple starting tips. Hope this helps!
