Use an item just as "inspiration"

Hello,

i have the following question regarding licensing:
I want to buy an item (video) to use it in an app as an animated background (e.g. moving particles). Now i realized that playing a video is poorly performant. I found out coding this background (e.g. with a particle engine) is much more performant. But i really want the background to look the same way.
So, is it allowed to reproduce (almost) the movement of the particles according to the video´s motions?

Thank you in advance!
Regards

I think you could contact the original author of the video to avoid any issues.
