I do understand the concern with crowding the screen. I gave this some more thought after my initial attempt to help and remembered that the source I'm vidding is actually what gave me the thought about simultaneously combining, so I've come back with a few more links:

The ending song for Galileo with karaoke work done by the subbing team for the first season: OST Galileo Kiss shite

In this you can see how the translation and original text of the song lyrics is placed on the top left, left edge, and bottom left of the screen, with animation of the text.

And a gif set about Tony Stark that elegantly shows how you can combine differing styles of fonts with subtle animation: futurist: i saw them all dead

This exercise is a challenge because it touches up against graphic design. I taught myself vidding and graphic design at the same time, so I hope you don't mind that I'm showing a bit of my passion about both in trying to help you! Some of these effects are a bit beyond what I can do myself with my software, so that's not to say that you should try to emulate it if it's too difficult. I'm fond of simple crossfade, myself. Besides, we all learn as we go, right?

I do hope it goes better for you and that your efforts yield something you like. Good luck!
