PLEASE UPDATE!!!???

I love this app so much but its just really hard making music videos. I have the audio but it takes forever to crop. Whenever I add pictures to the audio you always crop the audio to the picture, why!!!??? When I turn of ken burns and try to extend the picture to the audio I have to do it from the wrong end. WHY MAKE THIS SO HARD FOR ME!!!??? Plz fix?
