How to make a responsive landing page with video scrolling ( like Apple does ) ?
What are the options?
I know about ScrollMagic, I studied it. But there are problems with adaptability. The video does not adjust to the screen resolution, since the library itself sets its width.

Answer 1

Option one - google video api
Option twos - There you scrolled not video, but rendering pictures

Option three - it all depends on the circumstances. If something is not complicated, then at least js, svg or css is enough
