This movie actually makes sense to me. It was a bit of a shock to learn that you can't use videos of your animations inside apps. You need to use a series of stills called sprites. So I make a little animation in Anime Studio pro, export it as a series of stills (.png files), making sure I check the box to export 1/2 the number of frames. Then these .pngs need to be imported into a software that will squeeze all the little images onto a single page called a sprite sheet because this way you use way less memory.
Phew! so much to learn - but it's fun once you get over the hump of knowing absolutely nothing. Patience with being in that frustrating period of initial ignorance and believing it will pass is the secret of learning.
This movie comes from the website for a software called Texture Packer.
