its probably too expensive, but i thought, its worth a try:
Muvee AutoProducer
Muvee uses some sort of space-age technology to look for interesting
parts of your videos and synchronize cuts to whatever music you
choose. The results are great, and it takes very little effort to
create short videos that are sure to satisfy the grandparents. Muvee
AutoProducer has a free trial, and you can purchase it for $130.
