Animation for Website Hero Image

I am looking to replace the existing element animation on the hero image of our Samplify site - https://samplifyg8a.com/account/login (you'll just need to create an account to view).

I found the 3 adobe stock videos below that I'm hoping you can reference or use to create the new video.

1) Rainbow & Green - I'd like a much more subtle version using blacks, greys and pink (#FF008E).
- it would live behind the text so would have to be light on the left side and bottom so the text and logos are still visible.

2) Pink/Black - this animation would be on a transparent background with pink detail.
- I want it only to live on the right side so it doesn't interfere with content.
