Webpage objects extend beyond visibility
It isn’t browser’s fault, the video container has hardcoded width of 560px, that’s about 1960px on Nexus’s screen, which itself has width of 1440px. That’s webmaster’s fault, as it’s possible to make the container smaller on smaller screen.

As the browser simply does its job, there aren’t many solutions, but here’s what I can suggest:


rotate the screen (in landscape mode you have 2560px, that should be enough);
set “Request desktop site” in Chrome’s menu. Again, the website won’t be much more usable in portrait mode, but you’ll be able to see the whole video;
watch it fullscreen.
