Thanks for your feedback. We felt that it's hard to get the concept across without showing both clients. But thanks again for the input, we'll show the real interactions more prominently.
My initial reaction was, “no, there was no video on that page,” so I went back to look.
A lot of browsers disable audio on auto play videos. The fact that the controls are also hidden and the background color being the same as the website, it just looks like an animation, not a video. So some icons move but the meat of the video doesn’t start until after people will have disengaged.
