I would love this. My company just updated their public-facing website and it has a 28MB 1080p video playing in the page header. The site was outsourced, but I work as a web developer for some of our products and was asked by the marketing team to give the new site a look over.

The marketing team was surprised to learn how big the file was since the outsourced team "ensured" them that the new website would be lightweight. Oh well... Now the video has been reduced to a 16MB at 720p, which is still ludicrous to me, but they just really like having the video on the home page more than they want a truly lightweight page.

And to be fair, the video does not load when viewed on a mobile device, so at least there's that.
