If click on a picture it gives me the ability to add tags, but if I click on a video I am missing that ability. The same can be said when I view the "details" tab after I go into the properties window.

Whats going on? I got over 100 000 pictures, there no way id ever tag them... Id have to quit my job... yet videos (which potentially need to be tag because they can contain way more info) seems to be missing this critical tag aspect?
