After users find videos in your collection, you need to provide the content to them in some form. The best delivery format will depend on what the user needs and their circumstances. Some users, for example, will only want to view the video online. Others will want a broadcast-quality copy. Some users may have unreliable Internet and electricity, while others have high-speed broadband.
Video Sharing Formats
The archival concept of “generation” refers to the relationship between a copy of a video to its original. A single video can have multiple generations of copies, such as an original, a preservation master, a duplication master, a use copy, and a preview. Usually, a change in generation implies that the video has been transcoded into a different format (as opposed to being an exact copy of the original). Having multiple generations of a video therefore does not replace having backup copies of your original. Rather, its purpose is to allow you to use the video in different ways.
