While the
YouTube Help really points out that if you are a new User you have to ask them to be able to upload longer Videos it`s true that some of the older YouTube Accounts got that Option from the Beginning. YouTube had changed a few Times the Accounts Settings in the past and indeed I do remember that there was even once a Class that did allow you to upload longer Videos from Day One of YouTube.
As already stated - If you are a new YouTuber provide unique Content, gain enough Views and you should get that Option sooner then you probably will think.
