Another form of streaming is called downloadable streaming which is different than that of real-time streaming because the video files are placed on a regular web server. With downloadable streaming you can deliver the highest quality file because you can use encoding methods such as 2-pass VBR to vary the bit rate so that higher quality can be achieved over parts of the video that need it more. Since downloadable streaming videos are a file-based download where they don’t have to go through the user’s bandwidth pipe, the bit rate at various parts of the video can peak high. This is different than that of a CBR or a Constant Bit Rate encode. Downloadable streaming videos are great for short form content. With this type of streaming there is also an option to do a quality based encode where the compressionist can determine the quality that they want to achieve on a video file. It's important to note that when viewing a downloadable streaming video a copy does get placed on the viewer's computer but is one of the easiest ways to deliver streaming videos on the internet.
