Webflow animations problem


I have a problem. My client needs an animation on his Webflow website.

The biggest problem is that I tried to add this animation(.mp4 format) via Lottie animation, but this support only SVG and Canvas.

Also, I tried to find a fix via this community, but nothing helped. I want is there any way to make this animation?

Here is an example of animation: Dropbox - 000-StHero - FULL (1).mp4 - Simplify your life. What he needs is that this show and start automatically when someone scrolls into some section, I tried some HTML Embed solutions but always need to start the video and there is a design like when you watching YT video… Also bad quality…
