Hi Chris,
This is Cody Redmer (director and designer of Becoming a Legend). Yes, Trapcode Form worked perfect, it is well worth the purchase, I used it, and some real cigar smoke, to create the text smoking in. The only other tip I would give you is to have motion blur on, and crank the shutter angle.
Also, check out Trapcode’s Form tutorials, they’re a good start!
Hope that helps.
Cody
