Now with the that being being said: the animation will follow whatever your tag says. So as in my tagline: "making the world smile" all the words are rounded to represent the world and the word smile is curved in a toothy smile. I use that as part of my outro all my current videos.
Also, let's say you don't have a tagline or catchy phrase, and you don't want any flashy text. We what I will do is animate 30 seconds for you for $5. How do you determine the length? Either record it yourself, or estimate by the words on your script. Typically a page of script is a minute, so half a page would be thirty seconds.
