Re: 3d

Agree with post above.

Definitely get into apps like After effects first. That I would say is almost essential to know, least in my experience as a freelance editor.

I've wondered over time if I should need to know 3D. Short answer is no.
For any project that I've worked on and has required 3D then dedicated 3D artists are brought in.
Not so for motion graphics by after effects.
Its kinda expected that you can dive into that program and get gfx done. Like someone said, if you know that program you can pull off a lot of 3D looks if you know what your doing.

And a few little plug ins like Zaxwerks which can do some lovely simple 3D and your covered for most projects.
