CraigsList Video Ads

Hi,

I’d be curious to find out how to post video ads for my clients in CraigsList or BackPage.

I discovered a video ad here which I want to learn how to replicate:
http://sf.backpage.com/CleaningServices/affordable-house-cleaning-san-jose-call-909-246-0960/11210724

Within the ad html, it references this Gif file:

So, my question is how can you embed an autoplay video within a gif like that?

Thanks
