No, it’s not complicated if you use and take care of the audio/motion plugin. But at least it’s very nice.
It’s something like this (that I have made in at least 10 minutes) but in a better way and with more time. Use Motion to do some artistic design plenty of music and video effects are easy.
So the most important to do some graphics motion it’s to have an idea and take care of music. Then only you must have in your mind what do you want to do and let the imagination work. Or, as many I know, use the template telling us that you have do it.
Templates are nice, but please… work it more.
