What factors determine the amount that you must compress a video? The most important factor is the delivery method, because each method has file size limitations.

Take a look at the graphic below to see how each delivery method stacks up against each other. Video delivered over the web must be intensely compressed because of bandwidth limitations. The large amount of data found in a video takes a large amount of space within the data pipe of the Internet. As a result, video files must be as efficient as possible as they are being delivered over the web.
