I created a tool that allows users to collaborate and edit a shared video with a preexisting source. I was inspired by SoundCloud's commenting system in which users are able to comment at specific moments in a song. Sometimes videos are simply too long and you only want to see the good parts. This tool allows you to mark your favorite moments. After a moment is marked, it will play in the communal video for a short amount of time.
