Animating a straight line outwards from its center?

Apr 22, 2013 5:50 PM

Hi there,


I'm working on an animated logo for a trailer and want to create a straight line (between two lines of text) that begins invisibly in the middle then expands horizantally in both directions until the size of the line matches the text above and below.


The closest video example I can find would be in the trailer for The Thin Red Line (at 2:33) but I would like to find out how to do it in the fashion that I have described rather than the line simply coming in from one side


At present I've done a decent job by just keyframing the line's scale, though the downside of this is that the line doesn't become visible as soon as it starts expanding and can only start to be seen when it is about half size onwards


If anyone has any ideas on how I can accomplish this I'd really appreciate to know how it can be done!


Many thanks...

    Try a keyframed Crop effect for the reveal.

    Or try 2x Linear Wipes

    I like Jim's suggestion best. I have provided a quick tutorial on the subject.


    Is this what you had in mind?



    Yes, I know I should not have had to render it, but I was playing around with some text issues and changed over to software only, and forgot to change back until I saw the problem.

    Another quick red line all done within Premiere:


    Make a red color matte.

    Uncheck Uniform Scale.

    Set scale hight to a 1 or 2 (depending on the width you want)

    Animate scale width from 0 to say 75.

    Ann's way works too but it is hard to get the ends rounded off.
