Create a small movie with animals with Youtube scenes

Hi, I need to have a small movie (mp4).. you can create it from HD youtube scenes. In the movie there need to be small sessions...5-10 seconds each... of 12 different animals: 1: lion 2: elephant 3:crocodile 4:spider 5:tiger 6:leppard 7:fish 8:snake 9:giraffe 10:panther 11:gnoe 12: bird The jaws of the animal need to be going up and down... and close-up scenary... Because we will speak a voice-over behind your mp4... ok?
