Thank you for the feedback Lauro, and this on a Sunday evening.
Regarding the 1) https://www.socialita.nl/portfolio/video-background-header/. The video plays now full width, but the title and subtitle fo full width too while I want them to be aligned with the inner container. Please see screen shot.
Then regarding 2) https://www.socialita.nl/portfolio/hosted-video-full-width/. The video does not play automatically, nor there is a play button appearing. Then there are some disturbed video player commands out of line. Please see screen shot as well.
Thank you.
