One of the most pending suggestions and improvement being requested by youtube users has been fulfilled, youtube has now increased the video duration allowed per video from 10 minutes to 15 minutes. So now any video you upload can be of 15 minutes maximum length.
In the meantime, you may wonder “why now?” — the upload limit for non-partners has been 10 minutes for years. Well, we’ve spent significant resources on creating and improving our state-of-the-art Content ID system and many other powerful tools for copyright owners. Now, all of the major U.S. movie studios, music labels and over 1,000 other global partners use Content ID to manage their content on YouTube. Because of the success of these ongoing technological efforts, we are able to increase the upload limit today. We will continue our strong commitment to provide advanced technology and tools to protect the rights of small and large copyright owners worldwide. We’ll also do everything we can to release incremental improvements like this one that benefit our video creators.
