1. Actually , no , we didn’t forget anything. The video tutorial contains the basics on how to use the template inside After Effects (otherwise , the template wouldn’t have been accepted to Videohive).

2. I sense a condescending tone in your comment. That’s not something you want to do , especially when you’re asking for help.

3. When you’re asking a question , please be as specific as you can. From your question , I can’t deduce to which style you’re referring and what you mean by “change the width of my box” ; do you want to make it bigger (you can’t without major modifications of the animation) or smaller ?

4. I’ll just assume your question is in regards to style 01 and you want less text (smaller width). Here is a step by step video on how to do that: youtube.com/watch?v=sLA4Zpnl2Kc

Hi,
What you want is not possible out of the box but here is a video on how to change the background colors of a specific line within a style :

This is the easyest method to extend the duration without messing with the animated keyframes and all :

If you like the template , please don’t forget to rate it on your downloads section.

The easiest would be to render the lower third (RGB+Alpha Channel) for each scene (with different text) and then import the resulting ”.mov” files in After Effects , Premiere Pro or any other software you’re familiar with and place them on top of your video.

Here is how to render RGB+Alpha Channel :

There’s not a predefined action/option for what you want in this template and I’m not aware of an expression that could help you in that way.

Probably you’re making the position changes inside the comp “style 04” . Here is how to move the style 04 lower third :

Thanks for your help. That works

Ok , The problem you’re experiencing is due to the fact that you installed your version of After Effects in german and the template is created in an english version . You can read more about this on ADOBE website . All you have to do is change the language from german to english .
See here , here or here how to do that .
Thanks for your purchase.
