Keep the texts layers one frame for the most variety of texts flying all over.The texts must not extend past the original size of the comp containing them. Either way they will fly by so fast no one will notice they are cut off.
And lastly, Im not sure which part your talking about. Jump up and float away. If you are referencing the video. The word industry at 39 seconds. If thats what your asking. You just copy your text into a new comp, animate it jumping. then put the text particles comp above or below your jumping text comp, edit the timing so that it flows together. See how the text just pops on screen. It does not need a transition, just a hard cut.
