Creating a very long text box and make it slide

[Steve Bentley]

While there is nothing wrong with using a null (just create the null and pickwhip the text object to the null and then animate the null around – the text becomes a child of the null), the text object has it’s own position parameter. You can just animate that.
Be careful though. Dragging text vertically (and to some extent horizontally) can create judders if not done at certain speeds – its all to do with the way video refreshes (and film fps rates). Using motion blur helps too.

ah! and what’s a way to avoid that? higher up the fps rate when exporting? when you say it depends by the speed, do you suggest having it faster or slower?
also, for some reason I can paste text only when is smaller than 12pt, if I make it bigger it disappears, any idea why?

There’s some clues in your post that makes me think you might not be approaching this correctly. The font size is determined by the text object parameters so copying the text from another document shouldn’t be affecting the outcome in AE. But there might be other formatting information that is coming in with the copied text (leading for instance) that might push the text “out of view” in a single line text object. Can you upload the project? (just drag it into the reply box here)

Thats a ton of text. if you parent to a null like Steve was saying you might want to use an expression like this on the x position of the null.
just right click on position and seperate the dimensions

temp = transform.xPosition
temp+time*-60

You can change the 60 at the end to set the speed which the text will scroll across the comp.
