Video advice

[nobody]

I'm going to start shooting a new music video soon and I could use some advice. One of the things I would like to do is have my character change clothing/appearance while moving. I may also morph characters from one to another. In both cases, I'm assuming simple video transitions are probably not the "coolest" way to do this. I could get my costumes ready and change into them while repeating scenes, but what do I do to make it smooth and fluid? When it comes to faces/closeups, what's the best way to morph?
