Single plage site with more than one tab with embedded vimeo videos.

Description of your issue, suggested solution and other information

http://www.blackandwhiteandsex.com/
is a single-page wix.com site with vimeo videos embedded in iframes, under the "trailer" table and "the angies" tab. The iframe is inserted by some javascript. The videos are specified in json files like this:
https://static.wixstatic.com/sites/dbdeea_51ac6c3b06f8f100f3ba997173abde97_166.json.z?v=3

"videoId":"183444182","videoType":"VIMEO"

I don't know for sure if this is a generic wix.com thing but I suspect it is. I am curious if you guys will deem this feasible for youtube-dl to support.
