In addition to what @Oh.N8 asked for, please include a screen shot of the whole browser window (including you avatar in the upper right corner) with the error or problem showing. If you were using reference images or keyframes, please upload those as well.
It is best to be specific on what you want to see. When you say "add movement", that is kind of ambiguous. Try being more specific. Say you want the background to be solid blue (or whatever). Also, the model does not understand the concept of a word being negated by the word in front of it. So using "not [X]", "no [X]", "exclude [X]", "with no [X]", and "without [X]" does not work. It ignores the negation word and adds to the image the thing you are trying to avoid.
That said, it is a beta and unexpected things will happen. Please thumbs down any poor quality creations and indicate what is wrong with it. You have to hover your mouse in the lower left corner of the image to see the thumbs.
