AE CS5.5 and above(all).
This is auto-resizing text project. The box(square) is auto scaling while you typing, and fill all text. You can change even duration of text animation. You can easily change the box texture with premaded footages, or you can add your own. Also you can change box size, shadow effect, color.. etc. I Ultra HD 4K and Full HD resolutions are included. Very well optimized, thats why render time is minimum.
