Question about Video-Hosting

I see that I can embed Vimeo/YouTube or Wistia Links as Videos. That is great. I also can add Custom HTML so that i can use other hosters like Adilo.

I am thinking about which to use. Thinking about that, i want to consider that maybe later there might be Statistics included or that Videos may be marked as watched automaticly as soon a video is watched.

I think that FluentCommunity needs a kind of information from the video hoster to create these statistics etc....

I am afraid that i chose a platform and later i have to move all my videos to another place to get every benefit here?

I know that i am looking in the future - but maybe someone knows that maybe in embedded custom HTML these things might be impossible?

Thx
