Depth of Options
Pretty much everything you need to make a classy video is all right here. Premiere's titling feature is great for dropping in titles or scrolling credits throughout your video, and enables you to add several layers and different fonts to one "clip" of text. Also, as mentioned before, the new "Ultra Key" eliminates the need for going outside the program to key your badly lit green screen.
Premiere's built in titling tool does everything you need!
Just about every codec you can imagine is supported. Soon after getting CS5, a client requested a file in the Avid codec (have they heard about CS5 yet?!), and after downloading the free Avid codecs from their site, they popped up in Premiere's Media Encoder with no problems!
Export clips easily to a variety of formats, or put them in your queue and go back to work while Media Encoder exports.
The only third-party plug-in I immediately went out and added to the existing effects here was the Magic Bullet Looks, which I love, and it seems as though many of the third party developers like Red Giant have already begun made their products 64 bit compatible specifically for this CS5 release.
