Hi, I have 3 video clips. The first is of an actor, the second is one of the items from the link below and the third is a toy mouse. The idea is that the actor changes into the mouse. Is there any way for the "magic Particles" to be superimposed over the actor please? Many thanks Eric https://www.youtube.com/watch?v=d-ii4bBoJUk

I am trying to export the my video into powerpoint. Can you please tell me the best option (s) to use. When I view the completed exported video prior to inserting into powerpoint, it works perfectly. However, once I insert it into powerpoint it is very "jerky". Sometime last year i successfully inserted it into powerpoint with no problem, so I know it will work. Thanks Eric Berg
