How can I add text, graphic or animation to video ? For example,
I want to add "Happy Birthday to David" flashing graphic/text to
the video when kid is cutting his birthday cake and a "Yummy"
graphic text box on top of his younger sister next to him, to
enhance the picture. I'm using Premier Element 4 to do the
editing but can't find such add on function. If PE4 can't do
that, what consumer level software can help ?  Where can I
download those animated video graphic ? or I have to DIY ?  For
trimming video (like cropping picture), is PE 4 able to do that
?
