It takes a lot of time to upload my video
Depending on the internet connection you have, it will take more or less time to upload your video. If it takes too much time, it will be safer to upload the video from a computer in any of the University's computer labs.
It is safer too, to upload the video when the youtube website is not performing any maintenance on the server (more or less between 10 p.m. and midnight every night -check that!).
