Hello corona community :)

About the video:

i am creating some history about my game, and i need to create some "mini" introduction of the my different worlds on my game and create a full game trailer, the mini introduction per each world is some like cut the rope, the first level on first box they have a "mini" video to make a introduction.
i need a 2d video and 2d full game trailer.

but i never created a trailer or mini introduction, i need some help to know, what i need to create it, programs and other things.

About the sound:
i need to start creat sound to the game, any can recommend some programs etc that i should use to make greats sounds?

Thanks very much
