You have posted this in pretty much every thread you’ve started.
While we are very happy to help beginners, it is clear from the number of sites you are working on that you are not learning, or doing this as a hobby, but are working on sites for paying clients.
That being so, do you not think you should be putting more effort into understanding the code you are using? @SamA74 has explained why things are not working; you should now have the ability to go and solve it yourself - or at least to ask more specific questions.

I set the videos on my page at autoplay.
[/quote]I would recommend you don’t set them to autoplay at all. You have no way of knowing where somebody will be when they view your site. Suddenly having a video playing could be inconvenient/inappropriate. Leave your visitors to choose whether or not they want to watch.
Sorry, I don’t understand what you mean by that, but again, hiding controls from visitors is a very back policy. You should always allow visitors control over how they view your site. If you try to force me to watch a video, with no method to pause it, I’m likely to close the tab instead and leave your site altogether.
