App to collate videos recorded by multiple people

The premise is that you create a group that friends can join, record videos, and have all videos immediately available to splice together. The focus would be on simplicity and convenience. So for example if you and your friends go on a trip together, each person records their own video but it's all pooled in one spot so when someone wants to create a compilation, the "available media" folder is already filled with everyone's videos.
