Ron is driving an RV around Europe. He wants to be able to upload all his 4K videos to the cloud. Leo says that he can upload them to YouTube or Vimeo. Both support 4K, but he won't have sufficient bandwidth to do that. Leo recommends saving them to an external drive and then shipping them home. Or he can just send thumbdrives, which he can get as large as 256GB now. Shipping them would be the most efficient way to back them up. Uploading, even at an internet cafe, would take forever.
Leo also says that uploading in 4K is rather impractical as most of the video is highly compressed anyway and nobody is really seeing it. 1080p is plenty.
