Not is really hard, well im not sure how she did, but i can make that.
*1. you need the part of video or some gif and tri to convert that in fraps, i have done with one really old program "Photoscape" that program have one tool called "Gif" you move your gif and you will move to that plase and you will see all the fraps. if is video maybe some video editor with what you can save fraps. (that is the most bored part x_x)
*2. go to Ps and plase your fraps with your size, look if have one good quality, and work like any animation, add your text, modify your lights, add some map gradient, whatever you want that is the easy part.
After all you will see is really easy, you no are make some animation with your picture, just adding text on your gif.
Im not really sure, and i did that with that way. sorry if some one know another way.
