Thanks, but Observer isn't what we're looking for. We want the video background to stay the same.
The idea is:
- You have 3 steps,
- The section will be placed under a video background
- When you come to the section, step 1 will show, video plays from 0.0 to 0.4 then stop
- You scroll again, step 2 will show, video continue play from 0.4 to 0.8,
- You scroll 1 more time, step 3 will show, video continue play from 0.8 to end.
