hey guys just made a popping song on logic, but i dont know how to record the video?

i want it in this style

so basicaly i need to be able to sync the video and song, and also have different instruments in the corners, is this possible on imovie? or is there another software i have to download? (free) thanks guys
You need something more like Sony Vegas to do that...the best you can do it iMovie (to my knowledge cause I want to do this as well) is have a tile in the original video playing another one.
