There is no black background in the composition. You just need to render the video with Alpha, so that it looks transparent when you want to use it elsewhere.

To render a video with Alpha make sure to select “RGB + Alpha” in the Video Output option.

Here’s a short tutorial that explains just this: https://youtu.be/JFLBJH2aMpU

Thank you!

Thank you!

For as long as you want. You will just need to extend the duration of the composition and push to the end of the comp the “Matte” layer that fades out the scrolling text.
Thanks!

Yes of course, the project is fully customizable. You can hide or completely remove every element you want. That includes the small squares. If you’ll purchase you’ll find them easily inside the pre-comped scenes, where you can simply hide them by pressing the “eye” icon, or just select the layers and hit delete on your keyboard.
Thank you!

To modify my question. How do I get rid of the light “RampLight” and “RampLight AL on the project “opener”?

Hello viverae,
Just select them and hit delete. Or you can hide them by pressing the “eye” toggle on the far left of the layers name.
Thank you!

I would use the video wall background form the Promo, or the first scene of the Opener (scale the logo down a bit push it to the side so you will have your presenter in one side and the Logo on the other). But you could use both and alternate. For example, use the video wall for a Top 10 or other type of charts, and the other for more generic presentations.
Thanks!

Thank you, I will give it a try and come back with some screenshot for advice on what works better. Also, do you have any other color schemes for the package that would work? My aim is to have 10 in total. Thx

Please use the Universal Controls on the Final Comp to change the colors. Otherwise if you want to change them individually, you need to disable the Expression on the Fill Effect of the Layer you are trying to change.
