Media Gallery limits


Hey! So I've been using XenForo for a while and it's simply the best forum software.

Now I want to try a new site that would be focused on video upload through the media gallery plugin.

Are there any limitations? How would the site behave with thousands and thousands of videos uploaded?
Thinking of the site being hosted in a "perfect case scenario", will things start to break down or get unstable?
Does anyone knows about any site running XFMG with a high volume of videos?
