If this is motivated by a business need: Buy a subscription to Wistia for the next ~13 years, and/or Wistia plus your choice of blogging service.

If this is primarily not about video hosting but instead about getting you programming practice, this would be an exceptionally difficult first coding project due to the video and UX angles. A better first project would be building a basic blog, on which you could e.g. embed Wistia to do the heavy lifting on the video end of things.
