need to join video share site for soccer game videos

Any recommendations. I am using Sony play memories to create videos (Sony camera) but need a site where I can post them for the team to watch or get. (Share site) The damn games are 90 minutes so some videos are 11 mb or even 14 mb. I tried to convert them to mp4 but many are still 8-9 mb. Any help or recommendations appreciated.

Also, when i try to save them on thumb drive even my drive is 128 mb they are saying not enough space even though only 9 mb. Anyone know why?
