Need software for titles and credits of my work

Im a starting CG animator, and i need a program that will allow me to create great "headers" and credits for my work.

i mean really professional looking stuff. (must have the ability to add pics in the credits, or even video in a little view box. like when they show bloopers on certain films during the credits.

i would like the program to be free, but even if it had a 30-day trial or so, that would be great as well.

thanks in advance!
