I'm not sure which video ad it is but there are currently MAJOR issues with lag due to it - takes ages to scroll, massive CPU usage (and consequent battery hit) with >1.5GB of memory being allocated to Shockwave Flash when I checked in Chrome Task Manager. Killing the process immediately fixes things but it makes the website pretty much unusable on a desktop machine at present! There were also previous issues with sound from video ads playing without being requested, which was extremely annoying.
Any chance to just getting rid of video ads altogether please?!
