Wow lots of videos templates lol
I try to make an original but lots of nice graphic from video template as you can find on many many websites.
So rule is
"Content must be original and not copied from someone else" So let's be clear Is video template allowed?
This animation video looks good, I prefer this one to be the winner I haven't seen other video though, my internet connection is having a trouble playing video because of lack of reception from signal, will try to watch others soon.
Let's me introduce Bobby to you.
