"You Tube" is a very popular free video hosting and video sharing site where you can find and watch thousands of streaming videos, as well as upload videos in almost any video format to tag and share with others (videos can be made public or private). Videos can be categorized, rated, tagged, and commented. Registered members can upload an unlimited number of videos to YouTube.com, but there is an upload limit of 2 GB and 10 minutes in length per video file, so you can upload Full HD videos (1920x1280p). You can upload video file formats from most digital cameras, camcorders, and cell phones in the .AVI, .MOV, and .MPG file formats. For high quality vidoes, YouTube recommends uploading videos in the MPEG4 (Divx, Xvid) format resized to 320x240 resolution with MP3 audio. Video files uploaded to the service are converted to Flash 8 format for online video streaming. At the bottom of the page for every hosted video there is HTML source code to embed the video in a webpage, which you can use to make your embedded videos autoplay. YouTube supports mobile video uploads (upload videos from your phone or PDA). You can choose to broadcast your uploaded videos publicly, or share them privately with selected friends and family. Hosted videos remain on their servers until the users who uploaded them choose to remove them.
