I've got an ajax request that fetches an HTML string, like: 

<div class="video">...</div><div class="video">...</div>

and I want to count the number of "video" div's as soon as I retrieve the HTML from the server. Is there an easy way to do this?

I tried: 

.done(function(data) { 
        $(data).find('.video').length

but it returns 0.

Reset to default 13

According to what is returned, you have all .video elements in the root. So one way to get the number of .video elements is to use .filter method:

$(data).filter('.video').length;
