Youtube summarized has a wonderful abilty to bring out the data from an hour long video; it is just amazing, it is usally a hassle when i need to carry out some research for a project and if the data is avaiable in some video, then i have to spend almost an hour!! making sense of the information and still there is a very good possibility that even after spending a hour the info i may recive is irrelevant to my project, youtube summarized totally eliminates the wasteage of time

Minimal intervention and mostly accurate results.
