The company I work for is going to be making some How-To videos for Adobe After Effects CS4, and right now we're just brainstorming some ideas together.

Do you guys have any ideas for How-to videos you'd like to see?

If it's the AE umbrella you're talking about, then perhaps getting more aquainted with Adobe Dynamic Link, and how to use AE seemlesly with other products.
And if there's limitations, then definately discuss them...

Good luck!!!
