Flash / Animations for Slide Show

I'm putting together a photo slide show for a friend's wedding reception and need animations created to introduce the 3 parts of the video. Each animation to be approximately 15-20 seconds in length. If created in Flash it will also need to be converted into a format I can add to a video. I attached some examples of what I am aiming at. Of course elements can be added to create a better overall appearance. I may have a 4th animation, but I need to have these created first. In the first animation I would like a pink butterfly to fly across the screen and land on the bride's name that has gradually faded into focus. (perhaps the butterfly will have a shadow if it looks ok) Second animation I was thinking about a baseball rolling across bumping into the end and bouncing back a bit as the groom's name appears. The third animation will just be the pink butterfly standing on the baseball flapping it's wings as the words "Our Life Together" appears to be written on the screen.
