I've always seen the option of adding a location to a video when uploading it (Under the advanced settings, if you've never seen it) but never understood it. I presume it must serve a purpose, does anyone know what that purpose is?

I think it's the same purpose as adding geo-tags to your photos, a feature that a lot of cameras have. Basically you can see the exact place where the photo was taken. I don't see the added value tho, certainly not for videos. At least not in my case![]()
