I've been using PrP 5.0 for 1 1/2 years now, but am new to AE. I do light documentary work and productions for small non-profits-- and am just beginning. My question relates to what AE adds to what is now a very robust NLE in PrP. I can see a few additions like Warp Stabilizer and Lens Blur. But overall there seems to me to be a great deal of overlap, especially since I don't do Green Screen, Illustrator-like work etc. I'm not trying to be argumentative here, just asking where, once I've begun working in Premier (and Auditon or Soundbooth), when would I likely gain a benefit by jumping over to AE? Are there more or better effects? Do I need to learn Expressions, etc? I'm asking so I can concentrate on what to study in AE. Or, is it possible that PrP has gotten so good, that AE has become less essential for the likes of work such as mine?
After Effects has much, much more to offer than Premiere Pro for motion graphics and compositing. If you're not doing much with those things, then you are probably fine in Premiere Pro. Also, After Effect has much, much more automation and extensibility (through scripts and expressions and a richer plug-in API).
As an example of the superior compositing, see these two videos, which show a couple of ways of selectively applying an effect to just a person's face:
That kind of control isn't possible (well, not feasible, anyway) in Premiere Pro.
I recommend working your way through the basic materials about After Effects to learn what it's capable of. Then, at least, you'll know what tools you have in that part of your toolbox.
Thanks Todd, I'm on it. In fact, it was that "Getting Started..." page by you that reignited my question. I've already started that, and will jump to your two URL suggestions in the next day. I appreciate your answering.
