Advance Vimeo video on scroll

Hi All!

I am a designer trying out developing a website for a project.

Which includes a video playing on scroll.

Found a codepen but I am not familiar with the code architecture that my attempts are not working.

The main challenge is to use Vimeo embedded video instead of mp4 from the tutorial.
If anyone can help me, I would greatly appreciate it.

Thank you.
