Duplicate content question about videos? selfhost vs sponsor hosted
 

Nowadays are you much better off hosting your own promo videos if your sponsor allows it? Granted you save bandwidth and other things and of course programs want more analytics if they can get it.

But for SEO sake and other things, should you host all videos on your own servers if and when possible?

google dont crwal videos unless you give them video sitemaps.,
and for video sitemaps you dont have to host it.,

what google see is title , description are unique or not.

just write your own titles and descriptions for video and use hosted videos. you will be fine.
