Panopto Browser Extension
Panopto is an online video platform that enables its users to watch lectures, take tests, and participate in discussion forums through an interactive lecture player. For many people, this is the only way they can study and get a good grade without attending lectures.
This app is a chrome extension that can be used on any page with Panopto.
So, if you want to watch a lecture and want to be able to use it when the original video speed is too fast, this is the best solution for you.
It will be useful for a lot of people and especially for those that have to study in the middle of the night.
It has two modes: slow and fast. In fast mode you can see the current video speed. In slow mode you can adjust the video speed without changing the original video.
