How to have a Video Start When you Scroll over it

I am hosting my videos on Vimeo because they start faster than when hosted on Squarespace.  When they were hosted on Squarespace they only started when I scrolled over them which I want. On Vimeo you can't do this as they all start immediately. Does anyone know how to make my videos that are hosted on Vimeo only begin to play when I scroll over them?

 Go to the Vimeo video click the "Show options" link, and check the corresponding boxes next to "Loop this video," "Autoplay this video," or both either on or off. 

I only am using Embed or Code blocks not Video Blocks because Video Blocks do not start at the video at the beginning instead it starts them a few frames after the beginning.

Thanks for your response, but since I am not using Video Blocks the "Show options" link is not offered.

Any other solutions?
